Description: Stm32 of digital voice storage and playback system-based software design. The system has been collecting voice signal pickup by the bandpass filter and AGC, into the AD, then the data are stored in SRAM, band-pass filter is then sent by the DA, to restore the voice signal from the speaker. The system can be a good storage and playback voice signal. , The source is developed in mdk. The software design is divided into two modules: the compression and decompression coding and storage module. Compression PCM coding and ADPCM encoding the two available buttons store is the the FSMC store (256k flash) storage.
