How Audio Reversal Works

Audio reversal is a simple but powerful technique. The tool reads the audio samples from end to start, writing them in reverse order to create a new audio buffer. This means every detail of the original recording is preserved — just played backwards. The duration remains the same, and there is no quality loss since it's a purely mathematical operation on the sample data.
