• Consider allowing the user to provide presets of filters they like, for example…
• Use https://www.npmjs.com/package/@ffmpeg/ffmpeg and allow you to data bend in the browser without having to upload!
• We could provide just the conversion to raw and then back, to allow for people to bend outside our application, for example, using REAPER.
• Have a way for people to say what bends they liked and what they didn’t like.
