frequency splitter audio unit

Features & Capabilities

Multiband splits an audio signal into separate channels: one for each of up to four frequency bands. It is useful for doing multiband processing using effects plugins that were not designed for multiband processing. For example, you could do multiband compression using two different compressor plugins, one for bass and a different one for treble frequencies. Or you could process a chorus or flanger effect on the midrange frequencies only, leaving the bass and treble clean.

This plugin has two modes of operation: Multi-output and Link Group

In Multi-output mode, the app takes a single channel of input and splits it into multiple output channels.

Link group mode is a fallback support mode for DAW apps that don't support multi-output audio units. In Link group mode you duplicate the input track several times, once for each frequency band. Then the plugin filters out all but the selected bands on each of your duplicate tracks so that each track contains just one frequency band. It's called "Link Group" because when you duplicate the plugin across two or more tracks you can link the instances together across tracks so that the controls that set the transition frequencies between bands automatically synchronise between all the tracks in the group.

HOW IS LINK GROUP MODE DIFFERENT FROM USING HIGHPASS AND LOWPASS FILTERS IN AN ORDINARY EQ TO SEPARATE THE BANDS?

Whenever you play two copies of the same track simultaneously you must pay attention to phase alignment. For example, if you copy a track and invert the phase on one copy then the two copies will cancel each other out and you'll get no sound at all. Similarly, if you duplicate a track and process filters separately on each copy, when you combine the two copies back together you will usually get phase interaction at certain frequencies, causing some frequency ranges to be boosted and others attenuated. To avoid this, you would need to use crossover filters that are designed to preserve the phase relationships between each of the bands. The UI of this plugin makes it look like each band is created with a single lowpass and highpass filter pair but that is not the case. In addition to the lowpass and highpass filters we also need several phase compensation filters. Although that could be done with an ordinary EQ plugin it would be quite complicated to configure and test to ensure that no unwanted phase cancellation occurs.

WHAT FILTERS DOES THIS APP USE?

They are second-order Linkwitz-Riley IIR crossover filters. We use IIR filters to so that when you use many of our plugins in series for real-time performance you don't add audible latency to the signal.

Oh my gosh. Had it for a while but only used it as a utility to trigger sidechained bass stuff. But the more I play around with it, the more its MANY uses start to unfold - from the basic and utilitarian all the way on to wildly creative sound design stuff. Have you got a phase issue in a particular band zone that you can’t seem to fix with eq alone? Park this effect on the channel and center a band splitter to the affected zone, then just dial in as needed. Or how about a modulated bassline split three ways with separate modulation *on each band* - a compressor on the sub, distortion on the mid, and sideband-only reverb on the highs, nice and out of the way of the lows yet spacious and huge? Or motion multi-fx on EACH band? You can even use it on a fully mixed track to kind of unmix/remix, or on a master channel mix to control and finesse the spectrum as needed. There are a LOT of other creative applications to be discovered. Cannot overstate how powerful this is as a corrective and creative tool. Big thanks to the dev.

Very useful indeed and I want to love it but it’s very unstable and crashes, sometimes only band one will show so you have to reset all the time. It can render a whole track silent sometimes. I know it’s free but it needs to be better,,,I would be willing to pay for it if it were.

This app claims that it works in GarageBand, but it doesn’t. It doesn’t show up in the auv plug-ins list or in the inter-app list. I’ve refreshed both GarageBand and this, tried reinstalling, still doesn’t show up. I get that GarageBand has limitations, but don’t tell people it’ll work if it doesn’t.
