AAC and WMA are both lossy formats, so flipping AAC to WMA is really about compatibility: getting your audio into a shape the stubborn device or app will actually take. Where AAC struggles with older or stubborn hardware that only ever learned MP3, WMA earns its keep: it's built for keeping aging Windows Media software and old archives happy.

FYI

Small print: AAC and WMA are both lossy, so every re-encode shaves off a little more. Convert once, from the best source you have: not repeatedly.

Why flip AAC to WMA

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.

WMA is Windows' old house band: big in the early 2000s, mostly retired now. Windows Media Audio, in several variants including a rarely-sighted lossless one. That makes it the right destination when what you need is keeping aging Windows Media software and old archives happy.

Questions people ask

Will converting AAC to WMA lose quality?

A small amount: both formats are lossy, so re-encoding trims a little detail. Converting once at a decent bitrate keeps it inaudible for most ears.

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

In the same neighborhood: WMA runs MP3-ish sizes; the famous 'CD quality at 64 kbps' claim never quite landed, and you control the bitrate.

Where will the WMA file play?

Windows Media Player and legacy Microsoft software; little else without help. That's the usual reason people leave AAC behind: WMA simply opens in more of the places that matter.

How long does AAC to WMA 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.
