7.1 Plugin: highpass instead of lowpass filter #120

Closed pillepalle1234 closed 1 year ago

pillepalle1234 commented 2 years ago

In the 7.1 plugin there is a lowpass instead of a highpass filter in the Subwoofer section.

While both filters might be useful, a highpass filter is needed in 99% of cases, even closed box subs profit from one 10hz and below when used for movies to limit unnecessary excursion. Ported subs can´t be used without a highpass safely when listening at louder volumes.

Most consumer AV-receivers already apply a lowpass filter to the LFE and the rerouted low frequencies from speakers are lowpass filtered already.

I would like to make my own plugin but the script does not work for me, as i already mentioned in the diy-hifi-forum..

Thanks.

I have send you a modified plugin already weeks ago. Does it work now?

pillepalle1234 commented 1 year ago

Hi, yes it works flawlessly, thank you :)

Great, would you mind to share it with other Aurora users? E.g. open a GitHub repository for it?
