An extension built from the original
An extended mix gives a DJ more time to blend tracks. Extended.AI works with the song's existing material rather than composing new music. Stem separation can help build a beat-focused section, while the editor gives you control over the timing and transition.
Before your first mix
Which files can I upload?
The hosted editor accepts WAV and MP3 songs up to 100 MB and 10 minutes long.
Does Extended.AI generate a new song?
No. It extends the track using the song's own material, with an optional built-in or custom transition sound.
Can I correct the detected timing?
Yes. Listen to the preview and adjust the manual start marker when the automatic estimate needs correction.
