Time Scale Modification of Music Signal Using Harmonic-Percussive Separation
Htun, Lwin Cho
Oo, Hlaing Thida
This paper presents an algorithm for timescale modification (TSM) of music signal based onHarmonic-Percussive Separation. The mainproblem in time scale modification of music signalis because of transients at note onsets in originalmusic signal. These transients cause the timescaled result into stuttering distortion or loss ofpresence of original music. Many algorithms weredeveloped to reduce transient problems of musicand to commercially use the Time ScaleModification upon audio. In this paper, we solvetransients problems of time scale modification byfirst separating the music signal into harmoniccomponent which contains the sound componentsthat slow variation in amplitude over time andpercussive component which contains transients ofinput music. Median filter is used for Harmonic-Percussive Separation. The harmonic componentis modified with frequency domain phase lockedvocoder approach and the percussive componentis processed with time domain overlap addapproach. Finally, the modified harmoniccomponent and the modified percussivecomponent are superposed to get the time scaledmusic.
