Implementation of cochlear implant simulation, referred to as vocoder.
How to use:
vocoded_x = vocoder(x, rate, nchan, cutoff , vocoder_type, verbose)
The first argument is the signal.
The second argument is the sampling rate (preferred 16Khz)
The third argument is the number of spectral channels between 2 and 9.
The fourth argument is the cutoff frequency for envelope extraction. The higher the cutoff, the more fine structure will be available in the vocoded signal.
The fifth argument specifies the type of vocoder: either NOISE or TONE vocoder.
The sixth argument provides more details regarding the bandpass filters.
See the example file 'example.m' on how to use this code.
