Avisoft-SASLab Pro, version 5.2.03 (26 March 2012)
- The main window waveform and spectrogram overview display has been improved. The new option “Optimize waveform and spectral envelope overviews” on the command “File”/”File Open Settings…” can significantly accelerate 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 further speed up opening large files.
-
The spectrogram overview on the main window now supports floating point arithmetic that can create more precise spectrogram images.
-
The spectrogram calculation now supports multithreading in order to improve 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 also be activated by pulling it out of the top margin of the overview spectrogram.
-
The metabase display window can now be resized.
-
The whistle tracking algorithm has been further improved by adding the new option “monotonic” that can now better 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…).
