Audacity has a lot of low hanging fruits in the UX department. E.g. every single one of these "You have not selected anything to apply [feature X] to. Try pressing Ctrl+A to select everything and try again!" dialogs should just not exist (if nothing is selected, apply to all, done), or when exporting to a format which doesn't do separate tracks and there are multiple tracks in the same channel, Audacity just silently merges them (throwing away data). When recording while a track exists there's some way (outside of punch-and-roll, I think) to have it record into the same track again with no warning, throwing away data. Scrolling is vertical for some reason, even though horizontal scroll is the primary scrolling timelines.

I do not think you will be seeing any sweeping revamp if that is what you're concerned about. Tantacrul is really focused on smoothing pain points and removing ambiguity. The changes we have seen from him in MuseScore so far have been small but welcome.

Would you mind sharing what's the company/project? It seems very interesting.

In a past life I was the head of audio production for the Audiobook Creation Exchange (ACX), Audible.com's online production service for independent authors and narrators. My job was to help ensure success for the at-home narrators who had DIY recording rigs setup at their home office.

Awesome! Thanks for sharing.
