Vocal pitch detection for musical transcription

In this paper, an improved method for the detection of vocal pitch for musical transcription is considered and detected pitch is used as a technique for the extraction of musical data from the given audio input. Harmonics present in the voice signal are eliminated by filtering techniques and the resulting signal is divided into a number of segments based on the input sequence given by a metronome input. Pitch of each segment is calculated and compared with a stored frequency table to assign the necessary musical note. The assigned musical note is used for automatic annotation of singing voice in monophonic audio.
