I thought it might be a good idea to use some sort of compressed audio playback on Pokitto, to allow us to use a little better quality for streaming music from the SD card. Anyway, after pulling my hair out for a while, I am opening up the project in its ‘nearly working’ state.
Here is a femto project so far - adpcm test.zip (63.4 KB)
As you can hear, it sound awful. I’m not sure at this point if it’s the input data that is the problem, or the output not being handled correctly.
If anyone knows anything about the subject, or at the very least can see some stupid typo or something, don’t hesitate to post a comment!
