In this work, we explore the task of musical onset detection in Carnatic music by choosing five major percussion instruments: the mridangam, ghatam, kanjira, morsing and thavil. We explore the musical characteristics of the strokes for each of the above instruments, motivating the challenge in designing an onset detection algorithm. We propose a non-model based algorithm using the minimum-phase group...
This work presents an approach for pitch extraction based on Grating Compression Transform (GCT) on harmonically-enhanced Modified Group-Delay-gram (Modgdgram). The work explores the use of peakedness and high resolution properties of the group delay functions and the ability of GCT to smear harmonically related components in the spectrum and to track pitch across frames. The power spectrum of the...
