将字节数组转换为Wav文件[复制] 1个答案

I have a web service that returns an array of bytes and my intention is to convert said array to a .wav in the client (a handheld such as Blackberry). However I really have no idea of how to do that, I tried just making an FileOutputStream but of course that wouldn't play. So I am once again without knowing what to do. Any ideas?

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。但是我真的不知道该怎么做,我试着制作一个FileOutputStream但当然不会玩。所以我再次不知道该怎么做。有任何想法吗?

So, there are LOTS of .WAV formats, here's some documentation:

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/ (note endian changes)

http://ccrma.stanford.edu/courses/422/projects/WaveFormat/(注意字节序更改)

It's not just a stream of data bytes, but it's close... Just a bit of header and you should be good.

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。

I suppose you could also use something like http://java.sun.com/j2se/1.5.0/docs/api/javax/sound/sampled/spi/AudioFileWriter.html

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。
