The quest for mental peace and tranquility has always been an intriguing one. Music and meditation have always known to be facilitators of mental serenity but scientific evidence justifying the usefulness of the same has been sparse. Our team has analyzed the brain changes which are induced by yoga and meditation in a quantitative manner.

  • Detecting tāla Computationally in Polyphonic Context – A Novel Approach
    In North-Indian-Music, tabla is mostly used as percussive accompaniment for vocal-song in polyphonic-composition. Human auditory system uses perceptual grouping of musical-elements and easily filters the tabla component, thereby decoding prominent rhythmic features like, tempo from a polyphonic-composition. For Western music, lots of works had been reported for automated drum analysis of polyphonic-composition. However, in the […] keyboard_arrow_right
  • Speech and Music – Nonlinear Acoustical Decoding in Neurocognitive Scenario
    Scaling behaviour of frequency-wise amplitude variation of speech and music signal, over time, has been analysed using non-stationary, complex-network based method and found that it varies a lot from frequency to frequency for music whereas it’s almost consistent for speech signal. In this experiment drone signal is taken as the basic music signal and it […] keyboard_arrow_right
  • Speech Music and multifractality
    The musical structures for different ragas have their inherent complexities which can be determined with fractal techniques and thereby opens up the possibility for classification of different ragas. This in turn can help to understand the emotion that the raga elicits in general. Audio signal categorization is one of the rudimentary steps in applications like […] keyboard_arrow_right
