Audio Editing

I've always found how a user edits interesting, now this is common on desktop devices with the input device of a mouse, but how would we have to allow for fine-tuning on mobile, we may have to give a user a select amount of controls on the surface, but they have to dive deeper to get more granular control, such as going into a track to change the pitch, split, or trim etc...

This doesn't just go for editing content but compiling, maybe there are different modes that the user can switch between depending on the use case.

This is just the initial exploration, but I'm looking into the project as a whole, maybe a audio editing app for a podcast or an app that would allow you to make a mixtape, or a radio show!
