Abstract:

Swara is the basic component of Indian Music. Swara recognition is the starting point of music pattern classification in Indian classical music. The recognition of swara in real-time is often required for judging the quality of tone of a vocalist or an instrumentalist. In this age of reality shows of music, a stand alone electronic system for swara recognition is very relevant, where the system would precisely judge the contestant in terms of swara perfection. In this context a swara recognition system is designed and implemented on a Texas Instrumemts Digital Signal Processor TMS320C6713. In this system the fundamental frequency is tracked using FFT algorithm and also using a newly developed algorithm which works efficiently in Digital Signal Processors. The frequency so obtained is wrapped to a single octave. The fundamental frequency is then mapped to twelve distinct values corresponding to twelve semi-notes and displayed in the LED display of the DSP Processor. The efficiency of the system is tested in terms of memory usage and speed.
