Frequently asked questions
Can I mix different formats?
Yes — MP3, WAV, M4A and others can be joined; the result is a single MP3 or WAV.
What does crossfade do?
The end of one track fades out while the next fades in, for smooth transitions like a DJ mix.
Is quality lost?
Choose WAV for no further loss, or MP3 at 256–320 kbps for near-transparent quality.
