A voice recorder is essentially a digital device that records sound, saves it in file format, and transfers it to another device, such as a computer. Popular file types include MP3 and Audio Interchange File Format (AIFF).
Where can I hide my voice recorder?
Good places to hide your device include above the pedals, the back seat console, under the car seat, or in the pocket behind the passenger or driver's seat. Make sure you place your device, so the microphone is not blocked. This will help you get the best quality recordings with minimal noise or interference.
