- Automatic Recording: Each time a predefined threshold is exceeded within a certain frequency range a new *.WAV file is generated and the signals will be saved onto the harddisk for a selectable hold-time. This mode of operation is useful for long term monitoring.
- Normalizing of waveforms in order to generate comparable spectrograms from recordings made with different recording
- Trim function supports quick removal of undesired parts from the WAV file.
