I'm trying to make these long mp3s with this app I made. There is a bug in it (or in Firefox or Chrome) that only appears after forty minutes of playing which adds a subtle noise to the playback.
I don't want to hold up these mp3s by however long it takes to work around that, so I use the app to make five separate wav files. That turns what could have been an almost entirely automated process in which I have to carefully line up the almost-ends and beginnings of four files in an audio editor every time I make a change and do a build.
I can actually automate this part with sox, but it's a hassle, and I keep hoping that whatever change I'm doing is the final change. I have a feeling I now how this will end.
