推荐答案

相当混乱，但你可以尝试这样的：

Rather messy, but you could try this:

1. 使用isobox4j（见 https://contributions.coremedia.com/isobox4j/wiki/IsoParser ）来读取AMR音频输出3GP文件的。


2. 使用的<一个列出的选项之一href=\"http://stackoverflow.com/questions/3641920/how-to-en$c$c-a-wav-to-a-mp3-on-a-android-device/\">How为en code进行WAV，以在Android设备一个MP3来恩code吧。

1. Use isobox4j (see https://contributions.coremedia.com/isobox4j/wiki/IsoParser) to read the AMR audio out of the 3gp file.
2. Use one of the options listed in How to encode a WAV to a mp3 on a Android device to encode it.

没用过isobox4j：它开始工作，但我做之前转移到一个不同的项目，但它看起来像它会给你的东西，看起来像原始的PCM，你可以连接code

Never used isobox4j: started working with it but moved on to a different project before I was done but it looks like it will give you something that looks like raw PCM that you can encode.

让我知道它是否适合你。

Let me know if it works for you.
