I'm trying to play a beep at a specified frequency for a specified length of time. How is this achieved in android? I noticed that their is an AudioTrack api but they don't provide any easy examples on its usage.

Put the audio in the raw folder
SoundPool soundPool = new SoundPool(5, AudioManager.STREAM_MUSIC, 0);
int soundId = soundPool.load(context, R.raw.beep, 1);
// soundId for reuse later on
soundPool.play(soundId, 1, 1, 0, 0, 1);
//(soundId , LEFT_VOLUME_VALUE , RIGHT_VOLUME_VALUE, SOUND_PLAY_PRIORITY , MUSIC_LOOP ,PLAY_RATE)
Use the PLAY_RATE attribute to change the frequency of the music being played
and use the MUSIC_LOOP to determine how many times it plays

I'm wanting to create the beep programmatically as it is dynamic and frequency and duration vary. Does android not offer that feature? – user1406186 Jul 11 '21 at 12:06

This requires an audio file though doesn't it? I'm trying to generate the sound programmatically. – user1406186 Jul 11 '21 at 23:11
