Description
Before analysis starts, it would be great if the audio could be normalised to either
- max(abs(audio)) = 1, or
- percentile(abs(audio), 0.95) = 0.5 (or related percentile normalisation)
This would be good for analysis and display purposes.

This would be good for analysis and display purposes.
Just to flesh this out briefly:
- for visualisation it would obviously be helpful if the waveform and spectrogram representations made good use of the range they're given
- for analysis one could assign lower probability to low-amplitude signals, thus reducing the number of false positive pitch detections (and hence faster annotation)
