The audio tools focus on MP3: extract sound from an MP4, make M4A easier to open, or shrink a large WAV before sharing. Conversion cannot repair a bad recording or create audio where none exists, so check the beginning, volume, and ending after download.

- Use MP4 to MP3 when you only need the audio track from a video.
- Convert M4A to MP3 for voice recordings and services that expect a regular MP3.
- WAV to MP3 reduces size, but it is lossy. Keep the original WAV separately when quality matters.
- If there is no audio track, the container is damaged, or the codec is unreadable, processing stops with an error.
