Convert AAC to WAV
AAC audio has to be edited, and every editing save in a compressed format would compound the loss.

What actually changes
AAC and WAV are not the same picture in two wrappers.
The AAC stream is decoded to PCM and written as WAV. No further loss occurs from here, which is what an editing workflow needs.
Worth knowing first
AAC encoders add priming samples at the start of the stream, and decoders are supposed to discard them using information in the container. A raw ADTS .aac file has no container to carry that information, so the WAV can begin with a few milliseconds of silence that were not in the original.
Questions
AAC to WAV, answered
Does decoding restore quality?
No. It stops further loss. The AAC encoder's decisions are permanent.
Which bit depth do I get?
16-bit by default, which matches the effective precision of the decoded audio for normal listening.
