Hi,
I'm in the process of writing a series of posts looking at some of the internals of leJOS. The first is about the audio system and some (not yet released) improvements, it can be found here:

Hi Mark,
what format was the file you were trying to use? What problems did you hit?

Hi Andy,

It was the background music for my Space Invaders project; an 8 bit WAV file at 8Khz (down sampled from the original I composed in GarageBand). The problems were exactly as you show in your blog post; variability of the pitch and a very noisy output. I put it down to the quality of the EV3 speaker so it's great to see that with a little software love the quality can be improved.

Mark
