Dual Linkwitz-Riley Filters

Christian Budde,known for his free VST's and Synth Edit modules has a collection of very interesting plugins much like the one were discussing here today. Small, dedicated to one task and most of them do it well. It's a typical workflow enhancer. The concept is fairly simple. It's both a HP and LP filter. It has two cascaded butterworth filters (ie Linkwitz Riley fitlers) which allows you to effectively control your mix frequency wise.

Dual?

The big advantage of having dual filters is in the versatility it adds.Your able to use it as a bandpass with great control over the slopes. And most importantly it's simple. It's a small and dedicated plugin; it adds complete control just the way you like it.
The plugin is a great help for a number of things. You can use it to audition groups solo – HP or LP everything and gradually move your way up/down. This way you can exactly hear where your sound starts in the frequency spectrum.

Utilizing the VST in your mix workflow.

Now looking at the info sheet above, we can clearly see how this tool will come in handy. To breath air in your mix, cut away unnecessary frequencies. The tricky part about this method is to keep listening. Don't blindly follow charts. But do realise the sonic potential the gained headroom has in your production.

The plugin has a bypass or on/off switch for the HP and LP. The only downside to this plugin I can think off besides it's fairly dated appearance is the clicks and pops you get when doing fast transitions with the Freq parameter. But, other then that its a wonderful, lightweight tool that's proven to be a great help!
This was the first Freeware Friday! I will do my very best to make this a weekly thing; one freebie a week, with a little info about how I use it. Hope you enjoy the plugin and make sure to leave a comment!
