simple!
不知道你有没有现成的decode &encode
还有你是个人使用还是公司使用?

个人一般不用amr!

开始点是到www.3gpp.org上下载amr的代码看看!
接口很多!!

--AMR-NB--
The fixed-point (TS26.073) can be downloaded from:
http://www.3gpp.org/ftp/Specs/archive/26_series/26.073/26073-510.zip
Extract the soure into ffmpeg/libavcodec/amr
To use the fixed version run "./configure" with "--enable-amr_nb-fixed"

The float version (default) can be downloaded from:
http://www.3gpp.org/ftp/Specs/archive/26_series/26.104/26104-510.zip
Extract the soure into ffmpeg/libavcodec/amr_float

The specification for amr-nb can be found in TS 26.071
(http://www.3gpp.org/ftp/Specs/html-info/26071.htm) and some other
info at http://www.3gpp.org/ftp/Specs/html-info/26-series.htm

--AMR-WB--
The reference code can be downloaded from:
http://www.3gpp.org/ftp/Specs/archive/26_series/26.204/26204-510.zip
It should be extracted to "libavcodec/amrwb_float". Enable it with
"--enable-amr_wb".

The specification for amr-wb can be downloaded from:
http://www.3gpp.org/ftp/Specs/archive/26_series/26.171/26171-500.zip

If someone want to use the fixed point version it can be downloaded
from: http://www.3gpp.org/ftp/Specs/archive/26_series/26.173/26173-571.zip

我做过,有现成的代码!
一般高档的手机才会使用amr,不知你们公司是作什么的?

[winsome_zhong]

wav 转amr的也可以

[GoogleGeek]

其中你需要对pcm数据进行resample

[winsome_zhong]

做彩信的，想做个录音控件，再把录好的声音转成AMR

使用Window Media File Format SDK

[winsome_zhong]

Windows Media Encoder支持amr吗？
