Does MP3 to WAV Improve Quality?
No — and this is the honest part. MP3 is lossy: it already discarded audio data to shrink the file. Converting it to WAV wraps that already-lossy audio in a lossless container, producing a much bigger file that sounds exactly like the MP3. It can't restore detail the MP3 removed. Convert MP3 to WAV when you need an uncompressed editing input — not to "upgrade" an MP3. More on this in is WAV lossless? and WAV vs MP3. Need the reverse? Use WAV to MP3.
