Hi,
Is there an Audio Compressor available in Octave?
I'm compressing my noises in the worst way, as you can see in the "while" condition on the example below.
In my way, the peaks will be "clipped", and I would like to avoid my stupid workaround:
====================
crest_factor = 6;
typenoise = noise(10*44100, 1, 'pink');
[z, p, k] = butter(4, [100/(44100/2), 500/(44100/2)]);
sos = zp2sos (z, p, k);
filtered = sosfilt(sos, typenoise);
normalized = filtered / (rms(filtered) / 10^(-crest_factor/20));
#{
Now I'm making an stupid workaround, as the audio file must be in
a range from -1 to +1:
#}
while (normalized(normalized > 1) || normalized(normalized < -1))
normalized(normalized > 1) = 1;
normalized(normalized < -1) = -1;
normalized = normalized / (rms(normalized) / 10^(-crest_factor/20));
endwhile
audiowrite ('AudioFile.wav', normalized, 44100);
====================
Thanks in advance,
Renato
