Moving sound source parameter estimation using a single microphone and signal extrema samples

Neeraj Kumar Sharma, Sai Gunaranjan Pelluri, Thippur V. Sreenivas

ICASSP 2015accepted

Estimating the parameters of moving sound sources using only the source signal is of interest in low-power, and contact-less source monitoring applications, such as, industrial robotics and bio-acoustics. The received signal embeds the motion attributes of the source via Doppler effect. In this pape…

Multi-instrument detection in polyphonic music using Gaussian Mixture based factorial HMM

H. G. Ranjani, Thippur V. Sreenivas

ICASSP 2015accepted

We formulate the problem of detecting the constituent instruments in a polyphonic music piece as a joint decoding problem. From monophonic data, parametric Gaussian Mixture Hidden Markov Models (GM-HMM) are obtained for each instrument. We propose a method to use the above models in a factorial fram…
