Title: Subwoofer limiter appears to be broken, why is it boosting?
Post by: mattkhan on February 24, 2018, 06:28:20 am

The subwoofer limiter is described in https://yabb.jriver.com/interact/index.php?topic=62012.0 though the exact behaviour is not well documented.

However I can see that it is applying a boost centred on 40Hz when I would have thought it should be doing nothing.

The signal chain is playing full bandwidth periodic pink noise via REW at -20dB into MC, the subwoofer limiter is the only DSP option set and it is set to apply at -5.

frequency response graphs to illustrate show the signal with no limiter, with the limiter set and the signal below the point at which it should active (shows a boost), the signal as it starts to trigger the limiter and the signal with +1dB more added (which makes it behave like a BW4 at 40Hz).

I can confirm this. I'm seeing abotu 2dB of boosting per subwoofer limiter used.
