M4A to WAV Converter Online
Convert Apple M4A files to uncompressed WAV in your browser. Drop a voice memo or iTunes track, get a 16-bit PCM WAV ready for any DAW — no sign-up, no upload.
How to Convert M4A to WAV
No account, no upload — three steps on your own device.
Drop Your M4A
Drag in a .m4a from iTunes, Voice Memos, or a DAW bounce — up to 200 MB. DRM-protected M4P files won't decode.
One Click to WAV
No settings to fiddle with — output is standard 16-bit PCM with the source sample rate and channels preserved.
Download & Import
The WAV downloads instantly, ready to drop into a DAW, sampler, or editor without a codec in the way.
Why Notevibes M4A to WAV
Built for clean, DAW-ready output without a server in the loop.
Handles Apple M4A
iTunes tracks, QuickTime exports, Voice Memos, DAW bounces — any unprotected AAC-in-MP4 file decodes right in your browser.
Lossless From Here On
The output is uncompressed PCM WAV, so nothing further is lost when you trim, mix, master, or re-save the file in an editor.
Never Uploaded
Decoding and re-encoding both run on your own device. Your M4A is never transmitted, so there is nothing for us to store or delete.
DAW-Ready Output
16-bit PCM WAV is the one format every DAW, sampler, and editor opens natively — no codec passes on playback, no import surprises.
Source Settings Preserved
Sample rate and channel count carry over from the M4A, so a stereo 44.1 kHz recording becomes a stereo 44.1 kHz WAV.
Free, Anywhere
No watermark, no sign-up, no daily caps. Works in Chrome, Firefox, Safari, and Edge on desktop and mobile.
No Upload — Your Sessions Stay in the Studio
Unreleased mixes, client audio, private recordings: none of it should sit on a converter site’s server. Here the entire decode-to-WAV pass happens on your own machine, so there is no copy anywhere else.

When You Actually Need a WAV
WAV is the working format of professional audio — here’s where it matters.
iTunes Library to DAW
Convert unprotected M4A tracks to WAV before pulling them into a session
Voice Memos for Editing
iPhone recordings become WAVs you can trim, clean up, and master properly
Audiobook Processing
Turn unprotected M4A chapters into WAV for normalization and re-export
Sampler Prep
Hardware samplers — MPC, SP-404, Digitakt — want WAV, not AAC
Pro Tools Workflow
Sessions run smoother on PCM than on compressed deliverables
Audio Analysis
Phonetic and research tools almost always expect uncompressed WAV input
The Shortest Path From M4A to a DAW Session
You’ve got a reference track from iTunes, a voice memo take, or a client’s M4A deliverable — and your session wants WAV. Some editors won’t import AAC at all; the ones that do burn CPU decoding it on every playback pass. Meanwhile the typical converter site wants that audio uploaded, queued, and stored on hardware you’ve never seen.
One click, one WAV
This converter does exactly one thing: it decodes your M4A and re-saves it as 16-bit PCM WAV — the format every DAW, sampler, and editor on the planet opens natively. Sample rate and channel count are carried over untouched, and the file downloads the moment it’s written. No options to second-guess, no queue, no watermark.
Honest note: WAV stops loss, it doesn’t reverse it
M4A is lossy AAC, and no converter can restore detail the encoder already threw away. What the WAV gives you is a clean working copy from this point forward — trim it, process it, bounce it as many times as you like with zero generational loss. Use it to protect the audio you have, not to upgrade it.
Built so the file never crosses the network
Demos, client work, and half-finished songs are exactly the files you don’t want cached on someone’s server. Here the conversion runs on the computer in front of you — the browser does the decoding itself, and the WAV is written straight to your downloads folder. Disconnect from the internet after the page loads and it still works.
Where to go next
If you want a small shareable file instead of a big lossless one, M4A to MP3 is the sibling tool. Coming from lossless sources, FLAC to WAV and MP3 to WAV work the same no-upload way. And once the WAV exists, the online audio editor can trim, clean up, and mix it.
Need to Do More Than Convert?
The full Notevibes editor trims, mixes, cleans up, and applies AI tools to your audio — then exports to MP3 or WAV.

M4A to WAV FAQ
How do I convert M4A to WAV for free?
Drop your .m4a file onto the converter above and click Convert to WAV. The file is decoded and re-saved as uncompressed 16-bit PCM entirely in your browser, then downloads automatically. No sign-up, no upload, no watermark.
Does converting M4A to WAV improve audio quality?
No. M4A is lossy AAC — converting to WAV preserves the audio exactly as decoded, but it can't restore detail that AAC already discarded. What WAV gives you is a lossless working copy from this point forward: no further quality loss while you edit, mix, or re-save.
Why can't I convert my M4P or Apple Music download?
Files with a .m4p extension and Apple Music subscription downloads are DRM-protected, and a browser cannot decode encrypted audio. Only unprotected .m4a files — CD rips, iTunes Plus purchases, Voice Memos, DAW bounces — will convert.
What bit depth is the WAV output?
16-bit PCM, with the sample rate and channel count preserved from the source. A stereo 44.1 kHz M4A becomes a stereo 44.1 kHz 16-bit WAV — the standard format every DAW and editor accepts.
How big are the WAV files compared to M4A?
Roughly 5–10× larger. Uncompressed PCM takes far more space than AAC, so a 5 MB M4A typically becomes a 25–50 MB WAV. Check your disk space before converting long recordings.
Can I convert iTunes library files to WAV?
Yes, as long as they're not DRM-protected. Most iTunes Store purchases since 2009 are unprotected M4A (iTunes Plus) and convert fine. Apple Music subscription downloads are encrypted and won't work.
Is my M4A file uploaded to a server?
No. The whole conversion runs in your browser using the Web Audio API. The file stays on your device from drop to download — nothing is transmitted, stored, or analyzed.
Is the M4A to WAV converter free?
Yes — completely. No sign-up, no watermark, no conversion limits. The only cap is 200 MB per file.
