M4A and WMA are both lossy formats, so flipping M4A to WMA is really about compatibility: getting your audio into a shape the stubborn device or app will actually take. Where M4A struggles with older Windows software and stubborn car stereos that expect a .mp3, WMA earns its keep: it's built for keeping aging Windows Media software and old archives happy.

FYI

Small print: M4A 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 M4A to WMA

M4A is AAC in Apple's favorite outfit: the audio-only MP4 your iPhone speaks natively. It was born in 2003, popularized by Apple's iTunes Store, and its real weak spot is older Windows software and stubborn car stereos that expect a .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.

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 M4A behind: WMA simply opens in more of the places that matter.
