A Time-domain Algorithm of Extraction Singing Voice’s Pitch with Musical Instrument Accompaniment
Jiang Bo Cheng · Electronic Engineer · 2007
Extraction singing voice from music with music instrument accompaniment can be applied in many areas such as content-based music retrieval. Conventional time-domain algorithms perform poor in strong noise circumstance due to its remarkable diversity from ordinary speech processing. Newly-emerging systems dealing with singing voice and background music employ complex training models and realize it in frequency domain. With the consideration of hardware implementation and resource saving, our system proposes a new time-domain algorithm, which is based on human voice feature. The system adopted an open-loop and close-loop framework. Simulations on MATLAB show that accuracy of pitch extraction is superior to conventional time-domain algorithms and some other modified ones.
