Latest Patents
One of Schaffer's latest patents is a crowd-sourced technique for pitch track generation. This invention utilizes digital signal processing and machine learning techniques within a vocal capture and performance social network. It allows for the computational generation of vocal pitch tracks from a collection of vocal performances captured against a common temporal baseline, such as a backing track or an original performance by a popular artist. By leveraging large numbers of performances of a song, this technique can generate pitch tracks that are distributed for use in karaoke-style vocal audio captures and other applications. The computationally determined pitch trackings from individual audio signal encodings of the crowd-sourced vocal performance set are aggregated and processed as an observation sequence of a trained Hidden Markov Model (HMM) or other statistical models to produce an output pitch track.
