AAC. A .aac file is a bare AAC stream without the MP4 wrapper. AAC was designed as MP3’s successor and sounds better at the same bitrate.
WAV. WAV stores raw PCM samples with no compression at all. What you save is exactly what the editor sees, which is why studios and editors use it.
What happens to quality
WAV is lossless, but it can’t restore what the AAC encoder already removed. You get an exact copy of the AAC sound in a format editors accept, at a much bigger file size. Hear the difference between lossless and MP3 yourself.
