Frequently asked questions
Why extract to WAV instead of MP3?+
WAV is uncompressed PCM — no lossy codec artefacts. If you plan to process the audio further (EQ, compression, normalisation, editing in a DAW), starting from WAV avoids accumulating quality loss from multiple encode generations. MP3 is preferable for final delivery where file size matters.
What is the file size of WAV versus MP3 for the same audio?+
Uncompressed stereo WAV at 44.1 kHz / 16-bit produces approximately 10 MB per minute. MP3 at 320 kbps produces approximately 2.4 MB per minute. WAV is about 4× larger. For production use, the quality preservation justifies the size; for distribution, convert the finished WAV to MP3 or AAC.
Can I use extracted WAV in Adobe Audition, Reaper, or Logic?+
Yes — WAV PCM is the most universally compatible audio format across all DAWs. Logic Pro, Adobe Audition, Reaper, Pro Tools, Ableton Live, and every other major DAW reads WAV natively with no import conversion needed.
