Frequently asked questions
Does WAV improve the original MP3 quality?
No. WAV cannot restore detail lost during MP3 compression. Conversion is useful when an editor or application requires WAV input.
Why is the first conversion slow and the output larger?
An audio engine of about 32 MB loads on first use. PCM WAV is usually larger than MP3. Processing depends on your device and has a time limit.
