Why Convert AAC to WMA?
Converting from AAC Audio to WMA Audio (Windows Media) is useful when you need good quality at low bitrates. AAC Audio has limitations: slightly less universal than mp3 on older devices. WMA Audio (Windows Media) addresses this by offering good quality at low bitrates and native windows support. WMA (Windows Media Audio) is Microsoft's proprietary audio format that was once the default for Windows music.
Good news: While converting from AAC Audio to WMA Audio (Windows Media) won't restore any data lost during the original AAC encoding, WMA Audio (Windows Media) will preserve the current quality without any further degradation.
