alsa
- 基于ALSA的WAV播放和录音程序完整源码,程序包包含四个部分:WAV Parser、SND Common、Playback和Record。WAV Parser是对WAV文件的分析和封装,这里只针对Standard WAV File;SND Common是Playback 和Record共同操作,如SetParams、ReadPCM和WritePCM等;Playback和Record就分别是播放录音的主体了。原理很 简单,以Playback为例:从WAV文件读取PCM数据,通过I2S或AC97依
acm
- truespeech的acm压缩代码。解压操作只要同样申请一个truespeech的编解码器,输入truespeech,输出pcm即可-truespeech the acm compression code. Decompression operation as long as the same apply for a truespeech codec, input the truespeech, output pcm can
audio_codec_file
- 音频编解码测试序列,编码包括:aac,ac3,g711A,G711U,amr,g721,g723,g726,g729,gsm,imaadpcm,mp2,mp3,msadpcm,ogg,pcm,wma-audio codec file:aac,ac3,g711A,G711U,amr,g721,g723,g726,g729,gsm,imaadpcm,mp2,mp3,msadpcm,ogg,pcm,wma
ADPCM
- 将音频编码或者解码。可以按照ADPCM编码方式,或者将其按照ULAW、ALAW或者PCM进行编码解码。-encode or decode audio acording different codec such ADPCM, ULAW, ALAW.
audio
- 海思音频编解码程序,支持ADPCM\G711\PCM\G726等多种编码格式,包含编码录音和解码播放功能。对于音频编码入门者十分有用。-Haisi audio codec procedures, support ADPCM \ G711 \ \ G726 PCM encoding formats, such as containing encoding and decoding recording playback function. Particularly useful for audio
ima_adpcm_encoder_latest.tar
- This project features a full-hardware sound compressor using the well known algorithm: IMA ADPCM. The core acts as a slave WISHBONE device. The output is perfectly compatible with any sound player with the IMA ADPCM codec (included by def
