SD CARD SOUND RECORDING, PLAYBACK CIRCUIT PIC16F876A
https://pic-microcontroller.com/sd-card-sound-recording-playback-circuit-pic16f876a/amp/
The PIC’s CCP is used as a DAC to convert the digital data back to audio. The sound is converted to 20KHz 8 bits mono in a format similar to .wav files. The quality of the audio is reasonable. SD card interface the PIC in SPI mode. Reading and writing data is in multi-blocks. Memory is used at the rate of 20KB/s.

The circuit contains a microphone amplifier and a speaker amplifier. We can say it’s a digital voice recorder. S1 switch is for recording / play-back ( recording in ON position ). When S2 is OFF the IC goes in power down mode. S3 starts the recording or play-back and must be a push-button. For more voice recorder circuits check the list bellow.
