audio-pcm2mp3-with-libmp3lame-master.zip

#### 前言 本demo是使用开源项目lame来将PCM数据编码成MP3数据。（环境：x86_64 Ubuntu16.04 64位） ### 1、编译使用 **lame的编译：**(源码下载地址：[https://sourceforge.net/projects/lame/files/lame/](https://sourceforge.net/projects/lame/files/lame/)) ```bash tar xzf lame-3.100.tar.gz cd lame-3.100/ ./configure --prefix=$PWD/_install make make install ``` **本demo的编译与使用：** ```bash $ make clean && make $ $ ./pcm2mp3 Usage: ./pcm2mp3 <in pcm file> <smaplerate> <channels> <out mp3 file> Examples: ./pcm2mp3 audio/test1_44100_16bit_stereo.pcm 44100 2 out1_44100_stereo.mp3 ./pcm2mp3 audio/test2_22050_16bit_stereo.pcm 22050 2 out2_22050_stereo.mp3 ./pcm2mp3 audio/test3_22050_16bit_mono.pcm 22050 1 out3_22050_mono.mp3 ./pcm2mp3 audio/test4_8000_16bit_mono.pcm 8000 1 out4_8000_mono.mp3 ``` ### 2、参考文章 - [Is there any LAME C++ wrapper\_simplifier (working on Linux Mac and Win from pure code)\_ - Stack Overflow](https://stackoverflow.com/questions/2495420/is-there-any-lame-c-wrapper-simplifier-working-on-linux-mac-and-win-from-pure) - [使用libmp3lame库编码mp3\_太上绝情的博客-CSDN博客\_libmp3lame.mhtml](https://blog.csdn.net/bjrxyz/article/details/73435407) - [c++ - 使用 libmp3lame\_liblame\_lame 将单声道 PCM 文件编码为 MP3 - IT工具网.mhtml](https://www.coder.work/article/1215758) ### 附录（demo目录架构） ```bash $ tree . ├── audio │   ├── out1_44100_stereo.mp3 │   ├── out2_22050_stereo.mp3 │   ├── out3_22050_mono.mp3 │   ├── out4_8000_mono.mp3 │   ├── test1_44100_16bit_stereo.pcm │   ├── test2_22050_16bit_stereo.pcm │   ├── test3_22050_16bit_mono.pcm │   └── test4_8000_16bit_mono.pcm ├── docs │   ├── c++ - 使用 libmp3lame_liblame_lame 将单声道 PCM 文件编码为 MP3 - IT工具网.mhtml │   ├── Is there any LAME C++ wrapper_simplifier (working on Linux Mac and Win from pure code)_ - Stack Overflow.mhtml │   └── 使用libmp3lame库编码mp3_太上绝情的博客-CSDN博客_libmp3lame.mhtml ├── include │   └── lame │   └── lame.h ├── lib │   └── libmp3lame.a ├── main.c ├── Makefile └── README.md ```
