Why do some editors refuse AAC but accept WAV?

Licensing and simplicity: decoding AAC historically required patent-licensed code that many tools didn't ship, while WAV is raw PCM any program can read. Handing an editor WAV also skips on-the-fly decoding, which some older DAWs and samplers never implemented.

How much larger is the WAV than the source AAC?

Expect the file to grow by roughly a factor of ten — uncompressed PCM occupies about 10 MB per stereo minute at CD settings, regardless of how small the AAC was.

Is AAC to WAV the right move before editing a track?

Yes, if your editor lacks AAC support or you're planning multiple save-and-export cycles — working in WAV prevents each export from re-compressing the audio. The conversion can't recover anything AAC discarded, but it stops any further loss from that point on.
