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?
其中你需要对pcm数据进行resample
做彩信的，想做个录音控件，再把录好的声音转成AMR
