THE AUDITORY MODELING TOOLBOX
Go to function
LYON2011_closeagcloop - active gain control loop
Usage
[CF, decim_naps, naps, BM, ohc, agc] = lyon2011(CF, input_waves, AGC_plot_fig_num, open_loop);
Input parameters
| detects | 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. |
| coeffs | 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. |
| state | Plot automatic gain control figure. Default is 0. |
Output parameters
| state | 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. |
| update | decim_naps is like naps but time-decimated by the int CF.decimation. |
