I decided to work on this project out of frustration, probably shared with more people here, and that's why I'm submitting it.

Frustration is great to initiate action, but usually doesn't work well as a sustained source of motivation. Sometimes it's just a matter of rephrasing the situation. You have an appreciation for audio quality - let that (rather than the frustration) guide Recadio's continued development. Wish you best on the journey <3
