You will have to create the wave data yourself using a sine-function. Fill a buffer of shorts (for 16 bit audio) with something like this:
buffer[i] = (short) (Math.sin(((double) i / samplerate) * f) * Short.MAX_VALUE); (please correct me if I'm wrong) If you need a 5 seconds tone, I suppose you could just fill a buffer of size 5 * samplerate, but you could also try something smart with a loop and repeatedly feed the same buffer to the AudioTrack object. Just be aware of rounding errors and aliasing. On 31 aug, 20:28, Eduardo Aquiles <[email protected]> wrote: > You could use AudioTrack.
