Avisoft-SASLab Pro, version 3.0 (June 1997)
- Real-time spectrogram scroll mode implemented
- Manual Erase-mode in the spectrogram window. This allows to remove undesired structures from the spectrogram image.
- Harmonic cursor in the spectrogram window. This supports the determination of the harmonic structure (fundamental frequency) of the spectrogram.
- Enhanced amplitude manipulation (tapering, limiting, multiplying and dividing by files).
- Manual sample point editing in the main window. Editing (cut, paste, …) can be done more accurate.
- Graphical input of cutoff-frequencies in the filter dialogues from the spectrogram or spectrum display using cursors. This improves the usability of the filter functions.
- Undo of editing actions
- Synthesizer: Generation of harmonic signals by mouse drawing of the parameter evolution (fundamental frequency, amplitudes of harmonics, frequency and amplitude modulation)
