DEMO_HOHMANN2002 - Shows how to use the gammatone filterbank from Hohmann(2002)

Description

Part I: This example creates a 4th order gammatone filter with a center frequency of 1000Hz and a 3dB-bandwidth of 100Hz, suitable for input signals with a sampling frequency of 10kHz.

Part II: This example program demonstrates how to create and use the gammatone filterbank within the framework of Hohmann (2002).

Part III: This Example demonstrates how to create and how to use the combined analysis-synthesis Filterbank system.
