Determining audioformat of audio files in Android

Question

Is there a way to determine the audio format of an audio file in Android? On normal java I do it like this:

File file= new File(...);
AudioInputStream stream = AudioSystem.getAudioInputStream(file);
AudioFormat format= stream.getFormat();

Answer 1

android.media.AudioTrack[1] has the following methods to access information about audio data:

• getChannelCount to determine the number of channels
• getChannelConfiguration to determine if you deal with mono or stereo content
• getSampleRate to find out the sampling frequency

and

• getAudioFormat to determine if you deal with 8bit or 16bit sample width.

Answer 2

The AudioTrack.getXXX methods you list merely return the values supplied to the constructor. This doesn't solve the original poster's issue.
