What You Get
The output is an audio-only MP4 — your audio encoded as AAC inside an MP4 container, with no video track. That makes it drop-in friendly for video editors, players, and platforms that expect a .mp4 file. Note that MP4 audio (AAC) is lossy, so it's smaller than the WAV and can't exceed the WAV's quality. For a pure audio file, WAV to MP3 or WAV to M4A may fit better.
