Avisoft-SASLab Pro, version 5.2.13 (03 December 2018) The Derived element based parameters functionality of theWill-lessParameter Measurements tool has been extended. It now supports moreover multiplications and user-defined unvarying values. Avisoft-RECORDER, version 4.2.28 (11 October 2018) The BMU Project offline WEA wringer functionality has been updated. Avisoft-SASLab Pro, version 5.2.12 (16 October 2017) Two spare element separation (segmentation) options have been widow to theWill-lessParameter measurements tool: "automatic (spectral entropy)" and "automatic (spectral bandwidth)". These new methods represent volitional ways (besides the "whistle tracking" tool) for detecting tonal vocalizations in noisy recordings. Avisoft-SASLab Pro, version 5.2.11 (04 September 2017) A newWill-lessParameter Measurements tool option for measuring the elapsing of unvarying frequency (CF) sections of bat calls has been added. It can be accessed through the more... sawed-off in the Temporal parameters section. Avisoft-RECORDER, version 4.2.27 (21 July 2017) The new option "Monitoring" > "Enable monitoring watchdog" will automatically resume the monitoring mode without recovering from a recording hardware failure, such as an interrupted USB connection. The RECORDER USGH software now rejects disabled in-between channels from multichannel .wav files. Until recently it was necessary to use the channels 1...n (always starting with waterworks #1) - now it is moreover possible to select for instance the channels 2...n. The welding range on the Playback Volume tool has been increased from -40...+20 dB to -96...+24 dB. Avisoft-SASLab Pro, version 5.2.10 (17 January 2017) A phase scrambling option has been widow to the writ "Edit"/"Filter"/"Frequency Domain Transformation..." The sample rate of 384 kHz has been widow to the recording tool (selectable on "File"/"Sound Card Settings..."). The touch panel renaming tool now moreover shows the text modules that have been specified in the external text file and the new "Delete" sawed-off allows removing any existing prefix from the current .wav file. The File > Rename writ can now moreover add suffixes rather than only prefixes. The metabase and geolocation tools add export options for suffixes. In order to modernize the compatibility with third-party software, all sound files will now be saved with the lowercase .wav extension (rather than uppercase .WAV). The newly widow phenology tool (Metadata >Pinpointand create virtual Metatadatabase… > Virtual Metabase setup > Phenology) exports phenology histograms (number of .wav files on a day versus time of day table). See the transmission at page 131 for details. The Pulse TrainWringeroption "Add filename" has been extended by the two related options "to each row" and "with path". Avisoft-RECORDER, version 4.2.24 (11 November 2016) The default "trigger level (threshold)"on the Trigger LevelScaledialog box has reverted from 50 to 37 dB SPL in order to match the most recent recommendations of the RENEBAT II research project report. The USG Player 416H now moreover accepts 2-channel .wav files (channel 1 is routed to the outputs 1 and 3 and waterworks 2 to outputs 2 and 4). The software now supports measuring wool dB SPL values by inward full-scale values or by scale using a known reference signal source (drop-down menu item "Monitoring" > "Trigger level scale / Full-scale SPL range...). In order to modernize the compatibility with third-party software, all sound files will now be saved with the lowercase .wav extension (rather than uppercase .WAV). Introducing UltraSoundGate 116Un/116Unb (29 April 2016) The new UltraSoundGate models 116Un and 116Hnb are class-compliant USB audio devices (USB microphones) that can be used with both the full-featured Avisoft-RECORDER USG/USGH Windows software and other third-party (or custom) recording software on Windows, Linux, Android, iOS and OS X. Despite of their low power requirements (100 mA drawn from the USB port), the USG 116Un/Unb wiring units can still be combined with all UltraSoundGate traps such as the 1/4" Mic Power Module or the Charge Amplifier. Avisoft Bioacoustics introduced the first generation of class-compliant USB audio devices for recording ultrasound when in 2001 (see for instance the now discontinued USG 116). Avisoft-RECORDER, version 4.2.23 (27 February 2016) Adds the logfile stage format options MM/DD/YYYY and DD.MM.YYYY UltraSoundgate Player 416H suburbanite and interface implemented The newly widow "level meter mode" listbox on the "Spectrogram Settings" dialog box allows choosing between the default "peak level" and the "rms level" method in order to facilitate level measurements. The (broad-band) signal level is now moreover stuff displayed numerically in dBFS. Introducing Avisoft-UltraSoundGate Player 416H (25 January 2016) The new UltraSoundGate Player 416H provides four waterworks ultrasound playback at a sample rate of 500 kHz. Avisoft-SASLab Pro, version 5.2.09 (14 January 2016) The main window writ "Edit"/"Change Volume..." > "constant" now allows to enter attenuations directly in dB (through the newly widow option "dB"). The spectrogram window writ "Tools"/"Scan frequency silhouette and width envelope..." now moreover supports the option "Reject if peak ampl. < xxx dB" when the whistle tracking element separation method has been selected. The batch function "TemplateNavigateCorrelation on short files" has been improved (the template files can now be longer than the files to be correlated). TheWill-lessParameter Measurements tool got two new options ("each row", "with path")in order to streamline the "add filename" functionality. The new option "File/"Rename by text module"/"Show text modules on touch panel" allows to use the (text module) renaming functionality on tablet PC's. See moreover (Automatically) Classifying (Bat) Sound Recordings at page 11. The "File"/"FileUnshutSettings..." dialog box has been expanded by the option "change volume", which can be useful for analyzing sound files that have been recorded at low proceeds settings, such as those created by the UltraSoundGate 116Hnbm. The new spectrogram window menu option "Display"/"Show the Spectrogram parameters of this spectrogram..." displays the spectrogram parameters that were used to create the current spectrogram (including spectrograms loaded from .son files). The main window writ "Tools"/"Labels"/"(Re-)Number labels..." now allows inward an offset. The software now accepts DDE commands for opening sound files, loading .ini configuration files, batch processing and latter the application, which facilitates the integration with custom data management software. Sample commands can be found at SASLab_DDE.zip. The writ "File"/"Specials"/"Shred into numbered files..." has got the two new options "keep the original filename" and "add time offset to filename rather than file number". The software can now read the .wav file time stamps created by the Song Meter recorders of Wildlife Acoustics, Inc. (select the "TimeTurningFormat" list box option "Song Meter time stamp"). The batch writ option "Save one-dimensional transformations into single ASCII file" has been extended in such a way that the Spectral Characteristics measurement data sets can be saved instead of the raw power spectra. The new lines window commands "Data Export"/"Save as .at file..." and "Save as .flf file..." simplify the synthesis of broad-band signals based on the width envelope and/or the spectrum of natural vocalizations. The the real-time processing tool (Tools/Real-time processing...) option "Classify short .wav or .son files..." can now execute user-defined batch (.bat) files, which can be used for conducting feedback experiments or notification purposes. See the transmission at page 121 for details. The synthesizers have been improved by issuing aliasing warnings that pup up when the sample rate has been set too low. TheWill-lessParameter Measurement tool (Element separation: two or three thresholds) has got the new option "monotonic decreasing" that can help rejecting echoes in bat calls. Avisoft-RECORDER, version 4.2.22 (12 October 2015) The BatUndeniabilityTrigger Filter can now be combined with the "entropy threshold", which can modernize its efficiency in rejecting unwanted broad-band noise. The new writ "Monitoring"/"Email Error Report settings..." allows to automatically send an email when an USB (USG) or storage (HDD) error occurs. The NMEA 0183 GPS software interface has been extended in order to interpret GNSS (mixed GPS), GLONASS, Galileo and BeiDou sentences. The new DDE commands playlist_start and playlist_stop indulge to tenancy the playlist functionality remotely. Avisoft-RECORDER, version 4.2.21 (01 April 2015) The newly implemented Spectrogram Settings option "Show spectrum (dBFS vs frequency)" facilitates evaluating noise floors, estimating signal levels and adjusting trigger thresholds. In wing to the vital spectrum stereotype and peak hold diagram, its numeric peak frequency walkout can help identifying for instance species of bats. The new option can be found on the Spectrogram Settings dialog box, which is wieldy from the Configuration dialog box "Display settings" section through the "more..." button. See a screen shot. The new dXML metadata option "wait for input" supports the interactive metadata input by temporarily inhibiting the triggering mechanism during the data input period. Avisoft-RECORDER, version 4.2.20 (15 October 2014) The writ Play/Settings... has got two new options ("ext mute control" and "ext pause control") that indulge remote-controlling the commands Play/Mute and Play/Pause via the joystick interface (select "joystick b2 | b6" for the TRG input of the UltraSoundGate 116 and 216H). New installation programs (19 September 2014) Avisoft-SASLab Pro, SASLab Lite, RECORDER and RECORDER USGH now have each their own installation program and can be installed indepently from each other. The default program paths have reverted as follows: C:/Programs (x86)/Avisoft Bioacoustics/SASLab Pro, C:/Programs (x86)/Avisoft Bioacoustics/RECORDER, C:/Programs (x86)/Avisoft Bioacoustics/RECORDER USGH, C:/Programs (x86)/Avisoft Bioacoustics/SASLab LiteSurpassinginstalling updates using these new installation programs the previous installation ("Avisoft-SASLab Pro + RECORDER" or "Avisoft-SASLab Lite / RECORDER Demo") should be uninstalled from the WindowsTenancyPanel. Avisoft-SASLab Pro, version 5.2.08 (15 September 2014) The Pulse TrainWringeroption "Settings" > "Apply an upper width limit" has been widow in order to exclude pulses that exceed a user-defined peak amplitude. The new main window writ "Tools" > "Labels" > "Classify Element Sequences..." can snift user-defined label patterns. In combination with one of the nomenclature tools, this functionality could be used for recognizing increasingly ramified vocalizations consisting of a series of variegated elements. It is moreover misogynist as a batch procedure. The time coordinates exported by left-clicking on the spectrogram window in the reticule cursor mode will now moreover include the wool time withal with the video frame number when the LANC or SMPTE time turning format has been selected. The writ "Tools" / "Labels" / "Save labeled sections into numbered .wav files..." has got the new option "Add the filename of the original .wav file" and a "Digits" list box for the numbering. The writ "Tools" / "Batch processing..." > "TemplateNavigateCorrelation" now moreover supports .son spectrogram files rather than only .wav files. Avisoft-RECORDER, version 4.2.19 (20 August 2014) The playlist functionality has been extended in order to indulge randomized single-pass playbacks (option "randomize" zingy and "loop mode" deactivated). The option "Play" / "Settings..." > "seamless loop / playlist" now allows playing the .wav files on the playlist seamlessly without any gaps between them (the option "delay" must be deactivated for that). The new preset "Bat Calls" / "WEA OfflineWringer(BMU-Projekt)" provides the wringer settings recommended by the German BMU research project on reducing bat fatalities at wind turbines. The new Log file scuttlebutt option "Create will-less playback comment" in combination with "Create wav file label" automatically inserts playback comments into the currently recorded .wav file each time when a .wav file is stuff played. The new "Advanced USGH Device Settings" option "Show DIN" allows visualizing the DIN state on the real-time walkout as a undecorous trace. The new trigger option ".wav file playback" will work wideness variegated RECORDER instances for recording and playback. The immunity of the software versus sudden power loss conditions has been improved (the filenumber.txt file will not be damaged anymore on power failues). Avisoft-SASLab Pro, version 5.2.07 (25 June 2014) The commands "Edit" / "Synthesizer" / "Insert time code..." and "File" / "Specials" / "UltraSoundGate DIO" / "Insert time code..." have been extended by the new mode "Single Start Pulse", which can simplify the preparation of playback .wav files with integrated DOUT synchronization pulses for the UltraSoundGate Player 116 and 216H. The related batch writ "Insert USG DIO TimeLawmaking/ Pulse Train / Single Pulse" can slide the preparation of multiple playback files. The writ "Tools" / "Labels" / "Save labeled sections into numbered .wav files..." has got the new option "Reject file numbers". Avisoft-RECORDER, version 4.2.18 (06 May 2014) .wav file splitting functionality widow (commands "Monitoring"/"Split .wav files(s)" and "Options"/".wav file split trigger settings..."). By selecting the "trigger" option "USG TRG button" on the ".wav file split trigger settings" dialog box it is now possible (in the "permanent (unlimited)" recording mode) to create new .wav files by pressing the UltraSoundGate trigger button. UltraSoundGate 116Hm and 116Hnm have been tested successfully with a number of new lightweight 8" Windows Tablet PCs (December 2013): Toshiba Encore WT8-A Lenovo IdeaPad MIIX2-8 Dell Venue 8 Pro Asus VivoTab Note 8 Acer Iconia W3 The inbuilt GPS/GNSS receivers of the Toshiba and Lenovo 8" tablets can be accessed by the Avisoft-RECORDER software through the GPS option "use the Windows Location API". Short custom-made micro USB cables are misogynist on request. Avisoft-SASLab Pro, version 5.2.07 (06 December 2013) The writ "File/Specials/Add channels(s) from file..." has been expanded in order to uncurl the time turning of the two .wav files based on the UltraSoundGate DI tracks containing either SMPTE or LANC time code. In order to get this work, the "absolute clock time” option and the “SMPTE" or "LANC time lawmaking on USG DI (LSB)” listbox entry on the writ "Analyze/Time turning format" must be selected. The "Add channels(s) from file" writ can now moreover be invoked by drag&drop while the Ctrl key is pressed. The new option File/Advanced playback options/"Play through RECORDER USGH / UltraSoundGate Player" allows to play .wav files through the UltraSoundGate Player directly from within SASLab. The new option File/Advanced playback options/"Route UltraSoundGate DIO track (LTC) to the right playback channel" enables video playback synchronization. The newly implemented writ File/Specials/UltraSoundGate DIO/Toolbox... simplifies editing the UltraSoundGate DIO tracks. The new option "limit the wringer to the final xx % of the element" on the "Time derivative" option of theStreamlinedParameter Measurements tool allows measuring the Characteristic Frequency (frequency of the undeniability at its lowest slope toward the end of the call) for bat species identification. See moreover the screen shot. New writ Tools/Labels/Import time-frequency labels from .txt file... The label list on the "Label settings" dialog box can now moreover be sorted by the label text or the layer. Previously saved .cls files can now moreover be loaded by drag&drop either into the "Automatic Parameter Measurements setup" or the "Classification settings" dialog box. The new writ "File"/"Specials"/"Add silent channel" simplifies the preparation of playback files for the UltraSoundGate Player 216H. Avisoft-RECORDER, version 4.2.17 (20 August 2013) Bug fix for the playback with the UltraSoundGate Player 216H (solves a problem that can lead to random dropouts/clicks on some computers). The Player 216H can now moreover be used on Windows XP. The Weather data logging functionality has been extended in order to reap the temperature and humidity of a second Davis Intruments station. The "LOG File comment" functionality has been widow to the DDE writ interface. Avisoft-RECORDER, version 4.2.16 (21 May 2013) The new RECORDER USGH Trigger option "left-click / touch window area" has been widow in order to modernize the usability of the software on tablet PC's. The File Name Options writ has got the new option "GPS" that will suspend the current coordinates to the .wav file name. Avisoft-UltraSoundGate 116Hnm (11 May 2013) The new UltraSoundGate 116Hnm variants represent the smallest and least expensive members of the UltraSoundGate product family. The bundled Avisoft-RECORDER USGH software provides a number of unique functions that can turn a meaty Windows tablet PC into a powerful bat detector with capabilities that are not misogynist in any other competitive product. Avisoft-SASLab Pro, version 5.2.07 (08 May 2013) The label editing dilaog box has been extended in order to slide the intercative editing of a series of labels. The newly widow "proceed to next" option will move the focus of it to the next label when the OK/Next sawed-off is clicked (rather than latter the dialog box). Avisoft-RECORDER, version 4.2.16 (12 April 2013) The new "pause" option on the writ "Monitoring" / "Shutdown / Sleep time..." has been widow in order to reduce the power consumption on PC's that do not support a sleep mode. The writ "Monitoring" / "Daily watchtower actions..." adds the option "Move recorded files to external drive", which can be help minimizing the power consumption of battery-operated recording systems. The AutomatedUndeniabilityParameter Measurement tool has been extended. The "peak amplitude", and "energy" parameters have been widow and the new option "reject if width < xxx dBFS" can provide increasingly reliable min/max/mean frequency measurements (similar to the respective option on theWill-lessParameter Measurements tool in SASLab Pro). There is an spare log file (calls_files.*) that lists the matriculation frequencies (number of detected calls) for each .wav file. Note that the internal meaning of some of the options have reverted in version 4.2.16. It is therefore recommended to execute a reset and re-enter the desired settings on previously saved configuration files. A curvature parameter has been widow to the AutomatedUndeniabilityParameter Measurements tool that can help classifying barbastelle bat calls. The new option "seamless loop mode" on the "Play"/"Settings..." dialog box will perform the "Play"/"Loop" mode seamlessly without any gap between the end and the start of the playback file. The file list on the playlist window has been improved and the Insert/Append commands now support multiple selections. Avisoft-SASLab Pro, version 5.2.07 (08 March 2013) New "Energy" and "dB" parameters on the Pulse TrainWringertool. The zoom functionality has been imroved for touch screen operation (the former pan function on the main windows now moreover allows to zoom in and out by vertical dragging gestures. Frequency resonse files (.flf) can now moreover be specified with (negative) logarithmic attenuation values expressed in dB rather than linear factors between 0 and 1. The writ Analyze/Overview Parameters... now allows selecting (or hiding) the individual channels of multichannel .wav files ("Show Channels" section at the marrow of the dialog box). TheWill-lessParameter Measurements writ "Remove gaps between detected elements from file..." has been widow to the batch processing command. A cluster wringer option ("create will-less classes") has been widow to the spectrogram navigate correlation nomenclature tool, which can help analyzing repertoires. The "Previous/Next file" commands now moreover work with .son files on the spectrogram window. Avisoft-RECORDER, version 4.2.15 (21 December 2012) The new "sleep" option on the writ "Monitoring"/"Shutdown / Sleep time..." facilitates putting a palmtop or tablet computer regularly to sleep in order to proffer the shower life in long-term monitoring applications. Resume from sleep and hibernation now functions smoothly plane if the monitoring was running at the time when the PC was put to sleep/hibernation. The new "Device" listbox option "Playback" on the Configuration dialog box allows visualizing and processing the waveforms played through the Play menu. The 'WAV File Folder' device option will now processes the unshortened folder tree and supports the 'Automated undeniability measurements' tool. The GPS interface now moreover supports the Windows Location API, which makes it possible to use it on the new Windows 8 tablet PC's that come with an inbuilt GPS/GNSS receiver. The new option "Play" > "Show playlist entries on touch panel" facilitates conducting interactive playback experiments on tablet PC's. Avisoft-SASLab Pro, version 5.2.06 (29 October 2012) The new writ "File"/"Heterodyned playback mode..." allows playing when ultrasound recordings just like on a worldwide heterodyne bat detector (virtual bat detector mode), which can help understand how bat detectors work or may be useful to those who are used to work with heterodyne bat detectors and would like to protract this method on full spectrum recordings. The writ "File"/"Specials"/Georeference .wav files..." has been extended in order to winnow moreover the GPS coordinates that are stored in the .wav files created by the Avisoft-RECORDER software (new option "use the custom Avisoft Bioacoustics .wav file GPS chunk"), as well as .KML (Google Earth version 5.2 or later) and Garmin Training Center .TCX tracklog files. All georeferencing tools can now directly create the ESRI shapefile format (.shp), which can simplify the GIS-related workflow. The threshold of the Pulse TrainWringertool can no be specified relative to the overall peak width (new option "rel."), in order to largest manage varying pulse intensities. New comamnd "Tools"/"Labels"/"Save labeled sections of same matriculation into single .wav files..." New batch writ "Create section labels from waveform events" Unchecking the new option "launch setup dialog boxes" on the "Batch processing" dialog box allows bypassing the setup dialog boxes, which can simplify the (repeated) usage of this tool. Avisoft-RECORDER, version 4.2.13 (10 September 2012) The newly implemented ESRI shapefile format (.shp) options on the GPS module provide a increasingly straightforward interface to professional GIS applications such as ArcGIS or Quantum GIS. The optional user-defined dXML data records (including weather data) will moreover be saved directly into the shapefiles. The continuous KML tracklog file now optionally supports the "MultiTrack" format that adds time stamps (compatible with Google Earth 5.2 or later). Avisoft-RECORDER, version 4.2.12 (14 August 2012) An spare 'WAV File Folder' device list box option supports batch processing of .wav files. That way, the BatUndeniabilityFilter can be unromantic for instance to recordings that have been made with third-party bat monitoring systems. The related option 'copy source files into the subsolders ACCEPTED or REJECTED depending on the occurence of at least one trigger event' on the File Name Options dialog box facilitates filtering automatically recorded bat calls that are unauthentic by unwanted noise. See moreover Using the Avisoft-RECORDER BatUndeniabilityFilter. Avisoft-RECORDER, version 4.2.11 (21 June 2012) The BatUndeniabilityTrigger Filter has been improved by subtracting a maximum elapsing limit option, which can help rejecting unwanted signals that squint similar to bat calls but walkout a longer duration. BUGFIX : The incorrect handling of file numbers (introduced in version 4.2.10, 20 April 2012) that can under some circumstances overwrite older .wav files has been fixed. It may moreover be necessary to reset the Read Only symbol of the file "filename.txt" that is located in the data folder. The Playback Volume writ now allows adjusting the individual channels of a stereo .wav file separately. A configuration preset selection box has been added, which will be launched at the very first start of the software in order to simplify its setup for a specific application. Avisoft-RECORDER, version 4.2.10 (05 May 2012) The new commands Playback > Pause and Playback > Mute have been widow The individual items in the log files are now separated by tab stop notation in order to largest wangle them from Excel. The new options at "Options"/"Configuration management"/"Save mode on exit/" indulge to pinpoint whether the configuration file should be saved when the program is closed. The GPS receiver and weather station software interface has been improved in order to largest manage removed devices. Avisoft-SASLab Pro, version 5.2.04 (05 May 2012) TheWill-lessParameter Measurements window has got two preset buttons ("whistles" and "barks") providing towardly settings for either pure-tone, whistle-like vocalizations or noisy barks. The new "break" option allows directly measuring the silent time interval from the end of the preceding element to the start of the current element. SMPTE and LANC time lawmaking can now be synthesized either onto the UltraSoundGate DI track or normal audio waveform tracks (commands File>Specials>UltraSoundGate DIO>Insert time lawmaking / pulse train... and Edit>Insert>Synthesizer>Insert time lawmaking / pulse train...). The SASLab graphic user interface can now be configured for touch screen operation in order to modernize its usability on tablet PC's (command Tools > Touch Screen Optimizations...). The Previous/Next file writ has been remoter extended (new options on File > Specials > Previous/Next file writ settings...) The new writ "Tools" >"Real-time processing..." can execute various processing commands (similar to the batch processing tool) on newly recorded sound files as soon as they have been terminated by the recording software. The content of the "Class Count Statistics" report list will now be saved to disk in real-time (filename: ClassCountStatistics.txt, .html or .xml). The Graphic Synthesizer GUI has been improved (pan functionality added) The new writ "Tools" > "Labels" > "Filter labels..." allows to remove labels based on their label text strings. A related function has been widow to the Label Settings dialog box (new sawed-off titled "Select..."). The unseat frequency cursors on the spectrogram window now moreover measures the frequency slope between the two cursors expressed in kHz/ms or Hz/ms. YAQU PACHA recorded the echolocation clicks of the La Plata dolphin (April 2012) Workshop on Mouse ultrasonic liaison (16-17 April 2012) Avisoft Bioaoustics sponsored the workshop on Mouse ultrasonic liaison in Paris. See the Avisoft Bioacoustics presentation. The workshop nicely demonstrated that Avisoft Bioacoustics is the leading supplier of both ultrasound recording/playback hardware and sound wringer software for investigating USVs in rodents. Avisoft-SASLab Pro, version 5.2.03 (26 March 2012) The main window waveform and spectrogram overview walkout has been improved. The new option "Optimize waveform and spectral envelope overviews" on the writ "File"/"FileUnshutSettings..." can significantly slide viewing large sound files without missing short sound events. The underlying waveform and spectrogram envelopes will be saved to disk when the option "save envelopes to disk (*.env)" is activated, which will remoter speed up opening large files. The spectrogram overview on the main window now supports floating point arithmetic that can create increasingly precise spectrogram images. The spectrogram numbering now supports multithreading in order to modernize the performance on fast multi-core processors (new option titled "Threads" on the Spectrogram Parameters dialog box). The frequency cursor on the main window can now moreover be zingy by pulling it out of the top margin of the overview spectrogram. The metabase walkout window can now be resized. The whistle tracking algorithm has been remoter improved by subtracting the new option "monotonic" that can now largest distinguish between (simple) rapidly frequency-modulated calls and noise. It is now possible to record from the UltraSoundGate units through the newly implemented ring buffer of the RECORDER USGH software (new option on File/Sound Card Settings...). Avisoft-RECORDER, version 4.2.9 (26 March 2012) The new "Options"/"Spectrogram Settings..." dialog box allows adjusting the FFT window and verisimilitude map of the real-time spectrogram, similar to SASLab Pro/Lite. The new option "Options"/"Display"/"Status display" provides summarizing status information for long-term monitoring applications, which can be sent as meaty email messages (from "Monitoring"/"Daily watchtower actions..." > "create template for sendEmail.exe!") The new trigger option "call matriculation other than "?" allows limiting the triggering to unrepealable undeniability types equal to the matriculation defintions made on the writ "Options"/"Automated undeniability measurements settings..." A gate option has been widow to the playlist tool, which allows to limit the playback of the files in the playlist to user-defined daily time intervals. The whistle tracking algorithm on the BatUndeniabilityFilter has been improved by subtracting the new option "accept only monotonic structures", which can now largest disginguish between (simple) frequency-modulated calls and noise. The new writ "Monitoring"/"Ring buffer..." allows accessing the waveforms uninventive by the UltraSoundGate hardware in real-time from other custom software via a simple ring buffer (circular buffer) that resides on the nonflexible disk. Avisoft-SASLab Pro, version 5.1.23 (24 February 2012) An spare GPX/KML export tool on the metabease dialog box allows to export selected fields (columns) of the metabase table (containing GPS coordinates) into worldwide .gpx or .kml waypoint files. The writ Tools/Labels/Export label data... has been improved in order to facilitate the export of labels for (manual) measurement purposes. (see transmission measurements using labels). A "normalize" option has been widow to the Graphic Synthesizer writ Tools/Scaling... A "phase spectrum" option with phase unwrapping capabilities has been widow to the "One-dimensional Transformation" tool. The "Scan frequency silhouette and width envelope" writ has been widow to the batch command. The spectrogram cross-correlation nomenclature tool has been remoter improved. The new spectrogram window option "Display"/"Limit measurement decimal places to spectrogram resolution" allows to tenancy the number of the decimal places on the uninventive measurement values. The spectrogram cross-correlation nomenclature tool can now process increasingly templates (new option "use all template files in the selected folder"), can simultaneously perform will-less parameter measurements and will perform faster when executed in a batch process.
