Hi BD, I would go the NDK route for generating your sound, but for now you will have to pass the data back to the java layer to play it, I dont think the Audio APIs are the NDK yet.
Yes you have noticed you can't play too many at once with AudioTrack. This is a phone CPU speed issue. You can get a little bit more by setting a higher Thread priority. -niko On Oct 2, 8:41 pm, BD <mv.bharad...@gmail.com> wrote: > Hi. > I am trying to determine if I should go the ndk way to work on a music > synth app, but first wanted to do a sanity check in the java layer by > testing how many sine tones i could play concurrently, and so I tried > this.
