- optional GUI included-

inputs overview
1. 'linphase': symmetric two-sided response compensating magnitude while maintaining original phase information
2. 'minphase': one-sided response compensating magnitude with minimal possible group delay
3. 'complex': asymmetric two-sided response compensating magnitude and phasehttp://www.downloadplex.com/index.php?a=admin&b=programs&os=Scripts&add

mono or stereo impulse response (column vector)

FFT length for calculating inverse FIR

optional fractional octave smoothing (e.g. Noct=3 => 1/3 octave smooth, Noct=0 => no smoothing)

length of inverse filter (truncates Nfft-length filter to L)

frequency range to be regulated (e.g. [32 16000] => 32 Hz to 16 kHz)
% reg:
amount of regularization (in dB) inside (reg(1)) and outside (reg(2)) the specified range (example: reg=[20 -6] => inverts frequency components within 'range' with a max. gain of 20 dB,
while dampening frequencies outside 'range' by 6 dB)

window=1 applies a hanning window to the inverse filter

System Requirements:

MATLAB 7.5 (R2007b)
Program Release Status: New Release
Program Install Support: Install and Uninstall
