zplane.development has announced 4Tune, a licensable software technology for real-time pitch detection of a singing voice. 4Tune also computes the deviation of the pitch from a MIDI reference.
The technology is highly optimized for embedded devices such as the iPhone. The pitch tracking technology is based on the same core used by the professional grade pitch correction SDK élastique Tune which powers products such as Steinberg's VariAudio and FL Studio's Newtone and ujam.com.
More information will be available online at www.zplane.de soon.
