將字節數組轉換爲.wav java

Question

我有一個返回字節數組的Web服務，我的意圖是將所述數組轉換爲客戶端（如Blackberry等手持設備）中的.wav。然而，我真的不知道如何做到這一點，我試圖做一個FileOutputStream，但當然不會玩。所以我再次不知道該怎麼做。有任何想法嗎？

Answer 1

所以，也有.WAV格式的地段，這裏的一些文檔：

• http://en.wikipedia.org/wiki/WAV
• http://ccrma.stanford.edu/courses/422/projects/WaveFormat/（注尾數變化）
• http://www.lightlink.com/tjweber/StripWav/WAVE.html

這不只是一個流數據字節，但它很接近...只是有點頭，你應該很好。

我想你也可以使用類似的方式爲Web服務和設備上的媒體播放器之間被破壞的數據http://java.sun.com/j2se/1.5.0/docs/api/javax/sound/sampled/spi/AudioFileWriter.html
