Development of Low Cost Filter Banks for Audio Applications

An approach for low cost uniform and octave filter banks for Audio applicationsis proposed. The analysis stages of these filterbanks are based on IIR allpass secondorder sections with modified response.

Subjects:
an approach for low cost uniform and octave filter banks for audio applications is proposed
the analysis stages of these filterbanks are based on iir allpass second order sections with modified response
the modification is performed by forcing phase non
linearity at the analysis stage to be out of region of interest
by oversampling
the non
linear segments near the band edges are removed through subsequent synthesis filtering
compared to existing literature designs
the new approach offers a substantial lowering in computational power
and a lower input
the simulation and testing of this technique was performed using matlab software package
