AUDIO OUT • VIDEO LEFT BEHIND
Extract the first audio track from a QuickTime movie, choose the WAV depth, channel layout, sample rate, and optional time range, then download an editing-ready audio file. Your MOV is processed on this device—not uploaded to ToolMerit.
Choose a MOV file →The conversion engine loads only when you start converting.
MOV TO WAV CONVERTER
MOV describes a container. Its audio may use AAC, PCM, ALAC, or another codec. This tool uses a self-hosted FFmpeg WebAssembly engine to demux the first audio stream and encode it as WAV.
Your WAV player and file details will appear here.
The first run loads the local conversion engine.
Choose a MOV file to begin.
Local by design. The selected MOV and generated WAV stay in this tab. About 31 MB of WebAssembly is loaded from ToolMerit only after you click Convert.
Choose 16-bit for playback, transcription, or broad handoff. Choose 24-bit when the WAV will continue through editing or mixing. Choose 32-bit float only when the next tool explicitly benefits from it.
CONTAINER ≠ AUDIO FORMAT
A QuickTime movie can hold video, audio, captions, and metadata in separate tracks. Conversion selects the first audio track, discards the video track from the output, decodes the source audio, and writes uncompressed PCM samples into a WAV container.
OUTPUT SETTINGS
WAV is usually uncompressed, so each setting changes the amount of audio data written every second. Higher numbers do not restore detail missing from the MOV.
Practical for transcription, review copies, presentations, and broad software compatibility.
pcm_s16leUse when audio will pass through gain changes, processing, restoration, or a production handoff.
pcm_s24leUseful in compatible professional workflows, but often unnecessary for simple extraction or listening.
pcm_f32leWHY THE WAV GETS LARGE
Example: five minutes of 48 kHz stereo audio at 16-bit depth is about 55 MB. The same duration at 24-bit is about 82 MB. Container headers add only a small amount; actual results can vary slightly.
GOOD REASONS TO EXTRACT WAV
The right output depends on what happens next—not on the MOV extension alone.
Pull interviews, voiceovers, or on-camera speech into an audio editor without carrying the video track.
Start with 24-bit, source rate.Create a broadly readable speech file, then trim silence or irrelevant sections before sending it onward.
16-bit mono is usually sufficient.Store an uncompressed derivative when future access matters more than a compact transfer file.
Preserve source rate and channels.Use WAV when the receiving editor, sampler, presentation tool, or analysis workflow expects PCM audio.
Check its channel and depth limits first.BROWSER CONVERSION BOUNDARY
FFmpeg.wasm moves media work into your browser, but its own documentation notes that WebAssembly conversion is slower than native FFmpeg. This page deliberately limits one file to 200 MB and provides a cancel control.
The MOV is copied into an in-memory filesystem inside the worker. The WAV comes back to this page as a local browser object.
The wrapper and self-hosted WebAssembly core are site assets. No conversion file is sent with that request.
Long or high-resolution movies can consume substantial memory even though only their audio is exported.
WHEN CONVERSION STOPS
The MOV may be silent, contain only video, or store audio in a track the bundled core cannot read. Confirm that the original plays with sound.
Check the network connection for the first run, disable script-blocking for this page, and use a current desktop browser.
Trim or compress the MOV before conversion, close memory-heavy tabs, or use native FFmpeg for large production files.
Choose 16-bit, mono, a shorter time range, or a compressed format in another tool if uncompressed WAV is not required.
If Mono was selected, both channels were mixed down. Reset Channels to Keep source channels and convert again.
Download the completed WAV and open it in the destination audio editor. Conversion success and browser playback support are separate checks.
BEFORE YOU CONVERT
No. WAV is an audio format. This converter selects the first audio stream and intentionally excludes video from the output.
No. The source is read into the browser worker’s temporary memory. ToolMerit serves the conversion code, but it does not receive or store the MOV or WAV.
Keep the source rate when the next workflow does not specify one. Choose 48 kHz for many video workflows or 44.1 kHz when the destination specifically requests it. Resampling does not create new source detail.
No useful WAV can be created without an audio track. The tool returns an error instead of generating a misleading empty file.
The page lazy-loads a roughly 31 MB FFmpeg WebAssembly core only when conversion begins. Later runs in the same tab reuse that loaded engine.
One MOV at a time, up to 200 MB, with the first readable audio track used. Very long files, unusual codecs, damaged containers, or low-memory devices may require a desktop converter.
