Phase-based harmonic/percussive separation
In this paper, a method for separation of harmonic and percussive elements in music recordings is presented. The proposed method is based on a simple spectral peak detection step followed by a phase expectation analysis that discriminates between harmonic and percussive components. The proposed method was tested on a database of 10 audio tracks and has shown superior results to the reference st...
متن کاملHarmonic Single Channel Source Separation
Sound source separation has become a popular research topic in computer audition due to its wide range of applications in the analysis and manipulation of audio data. Applications of audio source separation include music information retrieval, automatic transcription of music, and sampling of musical sounds for electronic music composition amongst many others. Through this paper, different algo...
متن کاملHarmonic Separation Based on Independent Component Analysis Method
Harmonic separation plays an important role in power quality research due to the harmful impact to power system and electric apparatus. The accurate separation of harmonics is also the demand for filtering. This paper models the problem of harmonic separation as a blind source separation (BSS) task and the paper presents an algorithm called independent component analysis, which is widely used i...
متن کاملConstrained EM estimates for harmonic source separation
A constrained iterative method for harmonic source parameter estimation is proposed based on an EM algorithm with an intent for harmonic source separation. The problem of coinciding partials and interference among them in general is mitigated by the constraints on the “weak” partials on the stronger ones of the same harmonic source. A useful scheme to determine the weakness of a partial is prop...
متن کاملHarmonic Source Separation Using Prestored Spectra
Detecting multiple pitches (F0s) and segregating musical instrument lines from monaural recordings of contrapuntal polyphonic music into separate tracks is a difficult problem in music signal processing. Applications include audio-to-MIDI conversion, automatic music transcription, and audio enhancement and transformation. Past attempts at separation have been limited to separating two harmonic ...
