About this tool
WAV is useful for editors, DAWs, transcription tools, and legacy software that need uncompressed PCM audio.
WAV output is normally much larger than AAC because its samples are stored uncompressed.
Conversion time and memory use depend on the source duration, bitrate, and your device.
