[CF, decim_naps, naps, BM, ohc, agc] = lyon2011(CF, input_waves, AGC_plot_fig_num, open_loop);
input_waves | input_waves is a column vector if there's just one audio channel; more generally, it has a row per time sample, a column per audio channel. The input_waves are assumed to be sampled at the same rate as the CARFAC is designed for. A resampling may be needed before calling this. |
CF | The CF struct holds the filterbank design and state; if you want to break the input up into segments, you need to use the updated CF to keep the state between segments. |
decim_naps | decim_naps is like naps but time-decimated by the int CF.decimation. |
naps | naps (neural activity patterns) has a row per time sample, a column per filterbank channel, and a layer per audio channel if 'CF, AGC_plot_fig_num, open_loop > 1'. |
BM | BM is basilar membrane motion (filter outputs before detection). |
ohc | optional extra output for diagnosing internals. |
agc | optional extra outputs for diagnosing internals. |
Additional input parameters:
'CF',CF | The CF struct holds the filterbank design and state; if you want to break the input up into segments, you need to use the updated CF to keep the state between segments. |
'AGC_plot_fig_num=fn Plot automatic gain control figure. Default is 0.'
Flags: 'open_loop Use model with open loop. Default is 0.'
LYON2011 runs the CARFAC. That is, filters a 1 or more channel sound input to make one or more neural activity patterns (naps).
