Microsoft Windows Recording Audio. Versions of Windows prior to Windows 10 have an program called Sound Recorder. This pops up a small window and the settings are fairly intuitive as far as record, stop, and play. Windows 10, at least current editions, removes the Sound Recorder program and provides a Voice Recorder app.

This project focuses on building an Arduino Based Voice Recorder, which can also be abused as a spy bug . Our spy bug uses a small microphone to record the voice and it stores the recorded voice onto an SD card. It will able to record audio clips that are 2 minutes long, each 2 minutes long clip would be numbered serially.
SD/SDHC CARD SOUND RECORDER - PIC Microcontroller
https://pic-microcontroller.com/sdsdhc-card-sound-recorder/
This sound recorder has the same characteristics as the sound recorder with PIC16F876A. The difference is the supply voltage is 3.3V. This makes the direct drive of the SD card simpler. It also makes it easier to power it from a battery. 8MHz internal oscillator is used, if the frequency drifts it causes the playback to change speed. I left ...
