MP4 to WAV Converter

1. Upload your MP4 file (up to 500 MB).
2. Click 'Convert MP4 to WAV' — takes 10-45 seconds.
3. Download the WAV — ready for editing.

WAV is uncompressed — the standard format for audio editing. Extracting WAV from MP4 gives you a file that works in every DAW and audio editor without compatibility issues.

WAV is the universal format for audio editing — every DAW (Digital Audio Workstation) and audio editor supports it. Extracting WAV from MP4 gives you an uncompressed file that works in Audacity, Logic, Pro Tools, Reaper, Adobe Audition, and any other audio software without compatibility issues.

The converter decodes the AAC audio from the MP4 and writes it as uncompressed PCM WAV. Sample rate and channels are preserved. Output is a standard WAV file ready for any audio editor.

• Extracting audio from MP4 for editing in a DAW.
• Converting video audio for audio production workflows.
• Preparing MP4 audio for mixing or mastering.

• Preparing audio for transcription or analysis.
• Standardizing video-extracted audio to WAV.

MP4 → WAV converts AAC (lossy) to uncompressed PCM. The WAV contains the exact audio samples that the AAC decoder produces. Quality cannot improve beyond the AAC source, but no additional loss is introduced.

• Cannot restore quality lost during original AAC encoding.
• WAV files are 5-10x larger than MP4 audio.
• Metadata and album art are not preserved in WAV.
• Multi-track MP4s only extract the first audio track.
• Not suitable for portable playback (large files).

• Output WAV opens in every audio editor and player.
• Works with Audacity, Logic, Pro Tools, Reaper, Adobe Audition.
• Standard PCM WAV — universally supported.
• Accepted by every audio production platform.
• Not ideal for portable players (large files).

• WAV is ideal for editing but very large.
• For portable playback, use MP4 → MP3 instead.
• For lossless compression, use FLAC (smaller than WAV).
• Metadata isn't preserved in WAV format.
• Very long videos may take 30+ seconds.

WAV file is very large

WAV is uncompressed — files are 5-10x larger than MP4 audio. This is expected. For smaller files, use MP4 → MP3.

Metadata or album art is missing

WAV doesn't support embedded album art. Metadata is minimal. Use M4A or MP3 for rich metadata.

Audio quality didn't improve

MP4 audio is AAC (lossy). WAV preserves what's there, no more.
