EICELL - Excitation-inhibition cell computation for the Breebaart model
Usage
y = eicell(insig,fs,tau,ild)
Input parameters
| insig | input signal, must be an [n by 2] matrix |
| fs | sampling rate of input signal |
| tau | characteristic delay in seconds (positive: left is leading) |
| ild | characteristic ILD in dB (positive: left is louder) |
Output parameters
| y | EI-type cell output as a function of time |
Description
eicell(insig,fs,tau,ild) compute the excitation-inhibition model on the input signal insig. The cell to be modelled responds to a delay tau (measured in seconds) and interaural-level difference ild measured in dB.
eicell takes the following optional parameters:
| 'tc',tc | Temporal smoothing constant. Default value is 30e-3. |
| 'rc_a',rc_a | Parameter a for dynamic range compression. Default value is \(a=.1\) . |
| 'rc_b',rc_b | Parameter b for dynamic range compression. Default value is \(b=0.00002\) . |
| 'ptau',ptau | Time constant for p(tau) function. Default value is 2.2e-3. |
