## Frequently asked questions

### Does converting MP3 to WAV restore quality?

No. WAV prevents another lossy encoding step, but cannot restore information discarded when the MP3 was made.

### Which format suits an archive?

Keep the original first. WAV or FLAC can be lossless working copies when that fits the archive policy.

### Should every file use the same sample rate?

No. Match the destination specification; unnecessary resampling does not improve the audio.
