There are tons of karaoke applications for the iPhone, but a startup called Khu.sh is introducing a twist on the concept, "reverse karaoke," to the App Store.
There have been other reverse karaoke products, most notably Microsoft Songsmith, a Windows application that lets you record your singing, then automatically generates musical accompaniment. Songsmith even prompted a series of YouTube videos highlighting the hilarious badness of many of the resulting songs.
Khu.sh's iPhone app, LaDiDa, lets you do something similar on your iPhone. You choose a style (such as E Piano Pop or Dub Tone) and tempo, sing into the iPhone, and LaDiDa adds the music. You can also share the recordings on Facebook or Twitter. A $0.99-version of LaDiDa was first released last month, and Khu.sh added a free version (with fewer musical styles) called LaDiDa Lite (iTunes link) this week. You can check out the results in the video below.
This may seem like little more than a novelty, but if musical iPhone app developer Smule can have a hit with something like I am T-Pain (which overlays your singing with Auto Tune technology), I could see plenty of iPhone owners embracing this, too -- though it's a little more challenging without the help of a hip hop star like T-Pain.
Khu.sh is based in Atlanta and has raised $120,000 in seed funding, including $20,000 from incubator Shotput Ventures.
