Ääninauhoitin
An ääninauhoitin, or sound recorder, is a device used to capture and store audio. Historically, these devices relied on magnetic tape, with earlier forms using reel-to-reel tapes and later models utilizing compact cassette tapes. The recording process involved a microphone converting sound waves into electrical signals, which were then used to magnetize particles on the tape in a pattern representing the original sound. Playback involved a playback head reading these magnetic variations and converting them back into electrical signals, which were amplified and sent to a speaker.
The introduction of digital recording technology brought about significant changes. Digital ääninauhoittimet store audio information as
