Automatic Transcription of Polyphonic Piano Music Using a Note Masking Technique
نویسندگان
چکیده
This paper describes a polyphonic note detection system incorporating a simple masking technique that can accurately transcribe chords and polyphonic piano music. The system, developed in MATLAB, will take input files in .wav format. The music is segmented by using Note Average Energy (NAE) onset detection. Onsets are used to segment the music into note windows which are then analysed using the FFT. Following compilation of the frequency peaks in each note window, an iterative masking procedure is used to detect and successively extract the notes. The masking procedure uses a database of note masks which are compiled from multiple note examples using both monophonic and polyphonic examples.

Automatic Music Transcription based on Non-Negative Matrix Factorization
In this paper, we present a method for the automatic transcription of polyphonic piano music. The input to this method consists in piano music recordings stored in WAV files, while the pitch of all the notes in the corresponding score forms the output. This method operates on a frame-by-frame basis and exploits a suitable time-frequency representation of the audio signal. The solution proposed ...

متن کاملSONIC: A System for Transcription of Piano Music
This paper presents our system for transcription of polyphonic piano music – SONIC. SONIC takes an audio signal of a piano performance and tries to determine which notes were played by the performer, thus producing a list of notes and note onset times approximately matching the performance. SONIC is composed of three main parts: partial extractor, onset detector and note recognizer. We present ...
