Rati Sudha, Kathirvel Ayyaswamy, R. Sundaram · 2009
The main motive behind raga identification is that it can be used as good basis for music information retrieval of carnatic music songs or film songs based on carnatic music. The input polyphonic music signal is analyzed and made to pass through a signal separation algorithm to separate the instrument and the vocal signal. The frequency components (Arohana i.e. Increasing order of Music Pitch, Avarohana Descreasing order of Music Pitch) of the signal are then determined and we map these frequency in to swara sequence ant thereby determine the raga of the particular song.30-40 a sample of Base Ragas from 72 is being identified which will help more for music learners and musicians. Still now only vocal type of identification is being carried out and we provide the identification with string type Instruments of 1 or 2 Instruments mixture (violin/sitar/both).
