A New Method for Musical Onset Detection in Polyphonic Piano Music
نویسندگان
چکیده
In this paper, we propose a musical onset detection method, with reference to polyphonic piano music. The solution proposed consists of an onset detection algorithm based on Short-Time Fourier Transform (STFT) and Non-Negative Matrix Factorization (NMF). This method operates on a frame-by-frame basis and exploits a suitable binary time-frequency representation of the audio signal. To validate this method, we present a collection of experiments using a wide number of musical piano pieces of heterogeneous styles. Key-Words: Musical onset, Piano music, Non-Negative Matrix Factorization

متن کاملAutomatic Transcription of Polyphonic Piano Music Using a Note Masking Technique
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...
متن کاملMusical Onset Detection with Convolutional Neural Networks
Detecting musical onsets is the first step for many aspects of music analysis, but still lacks accuracy for polyphonic music signals. We perform an initial exploration of the effectiveness of using Convolutional Neural Networks for this task. On a dataset of about 100 minutes of music with 26k annotated onsets, our first experiments slightly surpass the best existing method while requiring less...
