Thanks to Ask the DJ's ultra-fast search engine, you add new tracks to your play-list in a flash. And thanks to Ask the DJ's revolutionary mix engine, the beat never stops.

Ask the DJ automatically indexes all your mp3 and AAC files when it's launched. To add a new track to your play-list, you just need to type a few letters of the title, the artist or the album's name. For instance, if you'd like to add Madonna's Into the Groove, just type mado groo. Ask the DJ immediately displays a list of matching titles, sorted by relevance.
You can also add tracks by dragging and dropping from the Finder or from iTunes.

Then, if you wish to optimize your play-list, you can do so by clicking the Sort button. Ask the DJ will rearrange your play-list so following tracks have matching tempos, rhythms and volumes.

Unlike any other software, Ask the DJ analyses beats to perform truly seamless transitions between tracks. Like a real DJ, it matches beats and adapts tempos whenever needed so the music always flows, even when cross-fading between tracks with different bpms.
Ask the DJ also cuts unrhythmical intros and outros, and levels volume. Better yet, all this is done automatically. You just need to click Play and dance.
You can also export Ask the DJ's mix art to audio files suitable for burning audio CDs.

Ask the DJ produces perfect transitions, even when mixing tracks with different tempos.
