Dear List,
We are working at an installation with four channel audio and a sub. Since the sub has not bas management we would like to build an frequency-separating filter in pd at 85 Hz. The cross over slopes should be as steep as possible. Has anybody ever implemented something like that? What about hip~ and lop~, they seem not to have a very steep cross over slope, 6 dB per oct. We would look for something like 36 dB per oct.
Thanks,
Florian
Apart from the fact that a subwoofer acts as its own lowpass filter, you could put 6 [lop~]s in a chain.
