- 读取SD卡存储的adpcm码，转换成PCM码后保存成wav文件。
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 defau
adpcm_decorde_corde
- 该程序用于处理音频数据，将从声卡直接采集的pcm格式的数据压缩成adpcm格式进行传输，从而达到节省流量的目的。-The procedure for processing audio data, collected directly from the sound card pcm format of the data compression into a transmission format adpcm to achieve the purpose of saving flows.
main
- ADPCM与PCM的编解码程序，效果不错，压缩率有待提高。感兴趣可以试一下-ADPCM and PCM encoding and decoding procedures, the effect is good, the compression ratio to be improved. Interested can try
dsp_adpcm_algorithm
- 德州仪器dsp5402芯片上实现pcm和adpcm语音压缩,有实际测量结果。程序环境是ccs。-pcm and adpcm algorithm based on dsp 5402.
voice2.0
- 基于stm32的数字化语音存储与回放系统的软件设计。该系统经过拾音器采集语音信号，经带通滤波与AGC后，进入AD，然后数据存入SRAM，再由DA送至带通滤波，由喇叭将语音信号恢复。该系统可以很好的存储与回放语音信号。， 本源码是在mdk上开发的。 软件设计分两个模块：压缩解压编码与存储模块。压缩编码有PCM编码和ADPCM编码两种可用按键选择；存储是FSMC存储（256k flash）存储。-Stm32 of digital voice storage and playback system
