Raw AAC files come from some phone recorders, internet radio streams and audio pulled out of videos. Raw .aac files have no chapter or cover-art support and some players skip them. Choose WAV to edit the audio or upload it to a service that requires uncompressed audio.
Frequently asked questions
Will the WAV lose quality?
WAV is lossless, so the conversion keeps every pixel or sample that is in your AAC file. It cannot bring back detail that AAC compression already removed, and the WAV file will usually be larger.
Will the WAV be smaller than the AAC?
No, usually larger: a minute of audio takes about 1.4 MB as AAC and about 10.6 MB as WAV. WAV is lossless, so its size depends on the audio rather than a bitrate setting.
