German software developer Algoriddim has introduced a new version of its digital DJ application for Mac OS X, djay 2.0.

The software now boasts a redesigned user interface and an improved audio engine. Users can expect better performance and a host of powerful mixing tools from the software, which integrates directly with iTunes.

New features include the Automix mode for automatic visual music mixing, a built-in sampler tool and a live microphone with real-time echo and voice pitch changing making way for unlimited mixing possibilities.

Karim Morsy, CEO of algoriddim, explains: "Our new Automix mode transforms djay into your very own DJ at your next birthday party. It's great fun to watch djay automatically throw together an awesome mix for you using the new built-in transitions like Backspin, Echo, Reverse, and Brake."

The new Sampler tool lets users create, play and loop sound clips taken directly from one of the two virtual turntables or a microphone. Such snippets can be saved for later use or be immediately integrated into the current mix.

Live Microphone lets digital DJ's speak into the mix or sing to the music, adding echo effects or changing their voice's pitch in real-time. External microphones and audio-hardware such as USB headphones used for pre-cueing are now automatically detected.

Mixes can also be recorded or sent using Apple's Bonjour software in real time for collaborative live mixing. After a mixing session, djay can export the song history as a playlist to iTunes or save it as a PDF.

Additional features include manual tap and beat-syncing and a time-stretching algorithm, which makes it possible to adjust a song's speed without changing its key. Additional sound transformations include pitch-shifting, reverse playback, equalizing, panning, reverb, echo and Audio Unit effect plug-ins. These transformations can be combined with using the new looping feature, where DJs can select a particular part of a song to replay continuously.

Another improvement means the software partially supports FairPlay DRM-wrapped songs purchased from the iTune Store. The application lets DJs play these songs, though recording and Audio Unit plug-ins can't handle DRM-protected songs.
