Heads up before converting to WAV
What this specific conversion changes about your audio.
WAV will not improve your M4A audio
Going from lossy M4A to lossless WAV cannot recover detail that M4A already discarded. You get a much larger file with the same audible quality. This only makes sense for editing or archiving workflows that need a lossless container.
Best practices for WAV
Small choices that keep your output sounding right.
- Play the first converted file before batch-converting the rest, so you catch a wrong setting early.
- WAV is lossless — ideal for editing or archiving. Expect files several times larger than an MP3 or AAC equivalent.
