What does MP4 to WAV Converter do?
MP4-to-WAV conversion removes the video stream and decodes the selected audio into uncompressed 16-bit PCM. WAV is useful for editing, waveform work and software that expects uncompressed audio, but its files are substantially larger than AAC or MP3. Tubelexity provides sample-rate and channel controls and processes the MP4 locally.

How local processing works
Processing uses FFmpeg.wasm locally in this browser. The media engine downloads on first use, but Tubelexity does not upload the selected media to a processing server.
Frequently asked questions
Does MP4 to WAV improve audio quality?
No. WAV avoids further lossy compression but cannot restore detail already lost in the MP4 audio.
Why is WAV so large?
It stores uncompressed PCM samples rather than compressed AAC or MP3 data.
Can I choose mono or stereo?
Yes, along with 44.1 or 48 kHz sample rate.
Is the soundtrack uploaded?
No.
