Review of F0 Estimation in the Context of Indian Classical Music Expression Detection
- 13 Downloads
The work addresses the need of fast and accurate F0 detection method for faithful transcription of Indian classical music. Three prominent F0 detection methods, viz. discrete Fourier transform (DFT), constant Q transform (CQT), and YIN algorithm are described and compared on the basis of accuracy and frame size against simulated signals of standard MIDI note frequencies. The same analysis is repeated on recorded data containing vocal recitals of eight notes from an octave in the equal tempered musical scale. That YIN method is most accurate and applicable for small frame size and is concluded.
