# Joachims Linkwitz-Riley v1.0

## 12 or 24 dB/oct cross-over filter.

This plugin can be used to split an audio signal into high and low, just like the cross-over filters that you find in a two-way loudspeaker.

How to use: The idea is that you send audio into two of these plugins. On the first plugin you select "Low", and on the second plugin you select "High". Set Frequency and Mode to the same values on both machines. After this you can do whatever to the two separate signals, and finally you can mix them together again.

PS: This filter is based on IIR filters, so correct phase cannot be guaranteed.

List of parameters
Enable | This parameter has 5 settings: 1. Off (shut off sound) 2. Low 3. High 4. Mixed low and high (not really useful actually) 5. Bypass
Frequency | Desired split frequency in Hz. This plugin is not really designed for automation, so expect some squeeky noises if you move the frequency around while playing audio through the plugin.
Mode | Here you can choose between 12 and 24 dB/octave. I might add 6 dB in a future release.
