How do I convert a voice memo to WAV?

Save the memo to Files (it's an M4A), choose it here and press Convert.

Will the WAV sound better than the M4A?

No — the same, uncompressed. It's for editing and software that needs WAV.

Is anything uploaded?

No. Your file is converted in your browser.

M4A

Lossy
Apple's format
Keeps chapters

AAC audio in an MP4 container — the format of iTunes and Apple Music purchases, iPhone voice memos and many recorders. It sounds a little better than an MP3 of the same size, and plays on Apple devices, Android, Windows and in browsers.

WAV

Lossless
Uncompressed
Made for editing

Sound stored exactly as it was recorded, with no compression. WAV files are big — about 10 MB a minute at CD quality — but every editor, DAW and computer opens them, so they're the standard for recording, editing and handing over masters.

When you'd do this

You want to edit or transcribe an M4A — an iPhone voice memo, an interview, a song — in software that only takes WAV.

What to expect

A 4-minute M4A at 256 kbps is about 7.3 MB; the WAV at 16-bit is about 40 MB.

Recommended settings

16-bit (the default). An M4A is compressed AAC, so a 24-bit WAV holds nothing more — just more bytes.

Where it plays

Any editor, Windows, macOS, iTunes and phones.

Good to know

Lossy to lossless can't bring back what the M4A's compression removed; the WAV keeps the sound as it is.
Chapters aren't kept — only M4B and M4A keep chapters.
A WAV made here can be up to 60 minutes long.

How to do it

Choose your M4A files, or drop them on the page — as many as you like.
Each is set to WAV. Change one on its own row if you like, and the bit depth and the channels in Settings.
Convert all, then download each WAV, or all of them in one .zip.
