Why convert AAC to WAV?
A WAV copy is useful when an editor or production tool cannot import AAC or M4A. It gives you uncompressed PCM for subsequent work without another lossy output step.
What happens to quality?
The 16-bit PCM WAV output will be larger, but it cannot restore audio information discarded during AAC encoding. Its audible quality is limited by the source.
Browser limitations
AAC decoding varies with browser and operating-system codecs, and DRM-protected audio is not supported. Processing uses local memory, which makes very long files harder to handle on mobile devices.
