[Enhancement] Use a power-law compression #9

Open RemiRigal opened 2 years ago

I think that the audio spectrogram could be greatly improved by using a power-law compression. A factor of ~0.3 could be a good start, it is pretty standard for audio signals.

Thank you for this great tool !

Thanks for the suggestion!

So, the height of each bar is displayed in raw decibels right now. Is your suggestion to alter these heights with Stevens's power law so that the different of heights between quieter sounds and louder sounds become smaller?
