MP3 to WAV
Convert MP3 audio to WAV. You are starting from MP3, which is the safe default: every player built in the last 25 years reads it. WAV is uncompressed PCM: perfect fidelity at roughly 10MB per minute. WAV is lossless, but it cannot rebuild what MP3 already threw away. You get a larger file containing exactly what the MP3 held, which helps before editing and achieves nothing as an archive upgrade. Runs on your own Vistalyth Tools instance. Files never reach a third party.

Frequently asked questions
- Will MP3 to WAV lose quality?
- Nothing is lost on this hop. Whether that is useful depends on the source: from a lossy original you get a faithful copy of already-reduced audio, not a restored one.
- Are tags and cover art kept?
- Yes, wherever the target has somewhere to put them. WAV carries the common fields; anything exotic in the source may not survive.
- Anything peculiar about MP3 I should know?
- MP3 cannot mark a gapless album boundary reliably, so expect a short silence between tracks unless the player understands the gapless tags.
- Can I convert a whole folder at once?
- Yes. Batch conversion applies the same settings to every file and returns them together.
