Processing audio output so as to create a Visualization

You can use the javax.sound.sampled package for this. To load an audio file, do this:

AudioInputStream audioStream = AudioSystem.getAudioInputStream(audioFile);

Mixer.Info[] mixers = AudioSystem.getMixerInfo();

Mixer mixer = AudioSystem.getMixer(mixers[mixers.length - 1]); //or something...

AudioFormat format = audioStream.getFormat();

byte[] audio = new byte[audioStream.available()];

audioStream.read(audio);

Now you have a buffer containing the bytes for the audio file. This consists of a couple of thousand elements, so it can be hard to grasp the meaning of the values. What you need to do is locate peeks in this byte code.

Hi,

i d like to know how to modify each channel of the stereo signal (left and right channel) separately using jmf.

I wanna write a pan effect filter just for education and then go on with the real project.

I wanna write it as a effect plugin.
