M4A (.m4a) · Max 20 MB
The converter defaults to the highest practical bitrate for WAV. Since WAV is lossless, every sample is preserved exactly. No encoder settings to worry about.
Garbage in, garbage out. The output quality depends on your source. A 128kbps M4A file won't sound better in WAV. Start with the best source available.
AudioUtils processes everything locally using WebAssembly. The encoder runs at near-native speed. A 10-minute file converts in seconds with maximum quality settings.
Frequently Asked Questions
Why convert M4A to WAV?
Professional audio editors and some hardware often prefer or require WAV format. Converting gives you maximum compatibility with production tools.
Is any quality lost?
M4A uses AAC compression, so the audio was already compressed. Converting to WAV preserves that quality level in an uncompressed container — no additional loss occurs.
Can I edit the WAV file in Audacity?
Yes. Audacity fully supports WAV files. Converting M4A to WAV is a common step before editing in Audacity.
What about M4A files with video?
M4A is audio-only. If your file is M4V or MP4 with video, this tool extracts only the audio track and converts it to WAV.
