How is audio stored in Java

This is a quick question, how is audio stored when it's in a byte array, like when a image is stored in a byte array there is three(Red, green, blue) bytes per pixel. So how is a audio stored in a byte array?

Thanks, Liam.

It's a combination of signals (analog / digital) having a unique frequency for each and every tone. And as it's said in the previous answer, yes, Pulse Code Modulation (PCM) is supported in java.

There are various possible encodings that are supported in Java. See:

The most simple form is PCM coding, in which each sample is a linear number that represents the sound waveform (which could be 1 byte for 8-bit encoding).

You also have to consider the number of channels (1 for mono, 2 for stereo). So 16-bit PCM-encoded stereo sound will require 4 bytes per sample, for example.
