Hi everybody,
so this is my firtst contribution here. One of my plugins I already use quite a long time and I believe could be useful for others too.
This is a spectral processing filter doing basically a frequency selective crossfeed, mixing signals from a stereo channel below the selected frequency to mono.
This is useful to bring the bass drum (or beat in electronic music) to the center.
Or to remove unwanted rumble from vinyl turntable recordings, these are typically low frequency signals of mutual polarity.
The plug-in is a close adaption to the Elliptic EQ function on a vinyl mastering console, especially the Neumann ones. The filter is a first order highpass in the side-channel (L-R difference). Higher orders can introduce strange artefacts at the crossover range that’s why I avoided higher orders. The Neumann EE70 module is first order (using an inductance) only as well and sounds good.
I added some more features missing in the hardware versions. You can choose how much the filter mixes the low frequency contents together with the Mono amount slider. And there is a bass compensation shelf eq integrated. this is useful because if you have out of phase low frequencies you will loose some of the bass which you compensate for. normally 0.5dB to a maximum of 2dB will be sufficient, of course this depends on the material.
I updated the header and added some error checking, so I hope this one conforms more or less to the standards here. It won’t check all typing entry abuse…
Create better masters and enjoy it,
