将字节数组转换为.wav java

我有一个返回字节数组的Web服务，我的目的是将所述数组转换为客户端（手持设备，如Blackberry）中的.wav。 但是我真的不知道如何做到这一点，我试着制作一个FileOutputStream但当然不会播放。 所以我再次不知道该怎么做。 有任何想法吗？

Answer 1

所以，有很多.WAV格式，这里有一些文档：

• http://en.wikipedia.org/wiki/WAV
• http://ccrma.stanford.edu/courses/422/projects/WaveFormat/ （注意字节序更改）
• http://www.lightlink.com/tjweber/StripWav/WAVE.html

它不仅仅是一个数据字节流，而且它很接近……只需要一点标题就可以了。

我想你也可以使用像http://java.sun.com/j2se/1.5.0/docs/api/javax/sound/sampled/spi/AudioFileWriter.html这样的东西。
