Frequently asked questions
Does converting MP3 to WAV restore original lost frequencies?
No. Frequencies discarded during original MP3 encoding cannot be regenerated, but converting to WAV ensures compatibility with editing software that rejects compressed MP3 streams.
What sample rate and bit depth does the output WAV use?
The output is formatted as standard Red Book CD audio: 44,100 Hz sample rate, 16-bit linear PCM, stereo or mono according to source.
How fast is the conversion process?
Because decoding and RIFF WAV container creation are handled natively in browser RAM, conversion is virtually instantaneous even for hour-long tracks.
