Are you open to a couple of feature suggestions from someone who uses Audacity for scientific applications?
1. An port of Audacity's "Noise Reduction" filter. I have done this once [0] (with some difficulty and no doubt with errors) and I am so tempted to just translate it to JavaScript and put up a PR, but I'm slammed right now.
2. It would be very useful to be able to view the spectrograph as an alternative to the waveform, rather than having it live in a separate "spectrum analyzer" pane. Especially if zooming along the frequency axis were implemented, this would make it much more useful for, well, spectrum analysis.
Thank you for making this. It's impressive in its own right but doubly so as a web application.

Those are both great ideas, especially the noise reduction function might be something that makes this tool quite useful for quick recordings! I actually tried implementing noise reduction algorithms in the past, but sadly could not get it to work properly. Maybe time to revisit! (ditto about the spectograms too)
Ooh, I actually was looking for a js noise reduction library recently. I might just translate it and put it up myself. :)
