Reading wav file in Java

Question

I want to read wav files in Java and I am going to classify them with K-means.

How can I read wav files in Java and assign them into an array or something like that(you can suggest ideas for it) to classify them?

EDIT: I want to use APIs for reading wav files and for K-means.

Solution 1

The official Java Sound Programmer Guide walks through reading and writing audio files.

This article by A Greensted: Reading and Writing Wav Files in java should be helpful. The WavFile class is very useful and it can be tweaked to return the entire data array instead of buffered fragments.

Solution 2

Equivalent to matlab's wavread function:

Solution 3

You could read the sound files using javax sound library and FileInputStream (found a nice example here) and treat the wave files as a vector of bits (0,1) or bytes.. using multiple sequence alignment (Wiki) create a distance matrix between every stream of bits/bytes, and from there, the clustering should be straight forward.

The Problem is, that this method is very sensitive to noise, etc, but it is worth a shot...
