Samantha Ronson, step aside — there’s a new DJ in town, courtesy of your iPhone and a new app called Touch DJ.
Landing in the App Store from developer Amidio,
Touch DJ stakes the claim of being the first full-featured DJ application on the iPhone, according to Macworld. It joins
Amidio’s stable of other music apps such as Noise.io™ Pro Synth, JR Hexatone™ Pro and Hot Dancer.
Touch DJ — billed as turning your iPhone “into a futuristic DJ MP3 mixer” — allows loading of two MP3/M4A files with real-time, independent manipulation, including effects, pitching, equalization, positioning, scratching and looping.
A unique, user-friendly interface, coupled with a highly advanced, zero-latency sound engine boasts “fantastic” results comparable to what can be done with pro hardware worth at least $1,000.
Touch DJ introduces “visual mixing,” which shows the audio waveforms next to each other on the iPhone screen. Because the device only has one stereo audio output, the visual mixing enables the user to see which tracks mix well together, adjusting them by sight. For instance, lower bass parts are rendered in a different color than other higher frequencies.
Other features include LP filter FX for each track, vinyl Spin and Break effects, an onboard, 3-slot sampler which accepts .WAV files and the ability to record your own samples using the iPhone microphone. 25 dance tracks from DanceMusicHub.com are included to get you going, and you can import your own MP3 files easily (Touch DJ can’t access your iPod library, however).
Touch DJ is available now in the App Store for $19.99 and requires OS 3.0 or later.
