关于gammatone的FIR实现 #4

Description

@seacj

你好
Gammatone滤波器组:性质、实现和应用写的非常好
我想请教关于FIR的实现。
你写道:

g = @(t, f0, erb) t .^ 3 .* exp(- 2 * pi * 1.019 * erb * t) .* cos(2 * pi * f0 * t);
h = g((0:1 / fs:signal_length / fs)', central_freq, band_width);
y = filter(h, 1, x); % y = filter(B, A, x);
y = conv(h, x); % 相当于和输入信号卷积

我想请问这里central_freq,band_width,f0 如何确定
