Acoustic feature based Musical Instrument Hierarchy and Its Application to Category level Musical Instrument Recognition
نویسنده
چکیده
This paper describes category level recognition of unknown musical instruments i e musical instruments which are not contained in training data based on an acoustic feature based musical instrument hierarchy The problem of how the unknown musical instruments should be dealt with is essential in musical instrument recognition However this problem has not been dealt with in previous studies In this study we propose category level recognition of the unknown musical instruments First we present a method for au tomatic acquisition of musical instrument hierarchy and then using this hierarchy we conduct experiments on recognizing the unknown musical instruments at category level In addition by introducing a process determining whether musical instruments are known or unknown i e whether the musical instruments are contained in training data or not we realize exible musical recognition that is individual instrument level recognition for known musical instruments and category level recognition for unknown musical instruments Experimental results showed that around of unknown musical instrument sounds in average were correctly recognized at category level

Acoustical-similarity-based Musical Instrument Hierarchy and Its Application to Musical Instrument Identification
This paper describes a method of constructing a musical instrument hierarchy reflecting the similarity of acoustical features. Although this acoustical hierarchy is useful for various purposes as well as investigating the timbres of musical instruments, it has not been reported in the literature. The main issues in constructing such a hierarchy are what feature space is used and how to obtain t...
متن کاملAudio-visual musical instrument recognition
In 2008, a humanoid robot developed by Honda conducted a symphonic orchestra in front of a live audience. It perfectly imitated the pre-recorded actions of the orchestra’s human conductor. Despite its realistic movements, it was suggested that the robot could not listen to nor interact with the orchestra as a true conductor would. For a robot to truly direct an orchestra, it would need to hear,...
متن کاملBiomimetic spectro-temporal features for music instrument recognition in isolated notes and solo phrases
The identity of musical instruments is reflected in the acoustic attributes of musical notes played with them. Recently, it has been argued that these characteristics of musical identity (or timbre) can be best captured through an analysis that encompasses both time and frequency domains; with a focus on the modulations or changes in the signal in the spectrotemporal space. This representation ...
متن کاملMusical Instrument Classification using Fractional Fourier Transform and KNN Classifier
Abstract— The classification of musical instrument, where the idea is to build a system that will listen to musical note and recognize which instrument is being played. In recognition of musical instrument the different musical instrument played based on isolated monophonic notes. Different feature component will be extracted and will be given to the classification system. Especially we will us...
متن کاملThe Significance of the Non-Harmonic "Noise" Versis the Harmonic Series for Musical Instrument Recognition
Sound produced by Musical instruments with definite pitch consists of the Harmonic Series and the nonharmonic Residual. It is common to treat the Harmonic Series as the main characteristic of the timbre of pitched musical instruments. But does the Harmonic Series indeed contain the complete information required for discriminating among different musical instruments? Could the non-harmonic Resid...
