A voice recorder captures and stores audio through a series of electronic processes. When you speak into the device, a microphone converts sound waves into electrical signals. These signals are then processed by the recorder’s internal circuitry and stored in a digital format, such as MP3 or WAV, on a memory card or internal storage. Playback is achieved by reversing the process: the stored data is converted back into electrical signals and then into sound waves through a speaker. This process highlights the core of how does a voice recorder work, seamlessly turning spoken words into digital files for easy retrieval and playback.
