You can convert AAC to WAV for free above: just know the WAV will sound identical to the AAC, not better; lossless can't restore discarded detail.

Let's be straight with each other: converting AAC to WAV will not bring back detail the AAC encoder already threw away. What you do get is a WAV that behaves like one: built for recording, editing and mastering, where every last bit matters: which is often exactly what an editor, burner or archive pipeline demands instead of an AAC.

FYI

Honest warning: a WAV made from AAC is lossless from here on, but it can't restore what the AAC encoder already discarded. It will sound exactly like your AAC: just bigger.

Why flip AAC to WAV

AAC is MP3's better-trained successor: cleaner sound from the same number of bits. It was born in 1997, an MPEG all-star team: Fraunhofer, Dolby, Sony, AT&T and Nokia, and its real weak spot is older or stubborn hardware that only ever learned MP3.

WAV is audio with nothing taken away: every sample intact, every megabyte accounted for. Raw PCM samples in a RIFF wrapper. No compression of any kind. That makes it the right destination when what you need is recording, editing and mastering, where every last bit matters.

Type	audio · lossy	audio · uncompressed
Best for	streaming-grade sound at friendly file sizes	recording, editing and mastering, where every last bit matters
Weak spot	older or stubborn hardware that only ever learned MP3	being carried around: it refuses to shrink
Typical size	similar to MP3, but it sounds better at the same bitrate: or the same at about 25% smaller	about 10 MB per minute at CD quality: ten times the size of an MP3
Plays on	Apple everything, YouTube, Android, modern players; patchy on legacy gear.	Universal on desktops and pro audio gear; clumsy on the mobile web.

Questions people ask

Will converting AAC to WAV lose quality?

It won't lose more, and it won't gain any back. The WAV preserves your AAC exactly as it is now: including whatever the original lossy encode discarded.

Will the WAV file be bigger or smaller than my AAC?

Bigger: usually several times bigger. WAV runs about 10 MB per minute at CD quality: ten times the size of an MP3, and none of that extra space adds quality to an AAC source.

Where will the WAV file play?

Universal on desktops and pro audio gear; clumsy on the mobile web. That's the usual reason people leave AAC behind: WAV simply opens in more of the places that matter.

How long does AAC to WAV conversion take?

Seconds for most files: audio is light work. A long recording might take a minute; your file auto-deletes from our servers within an hour either way.
