Filter

The Filter module looks, feels, and sort of sounds like a typical EQ, although the processing behind the filtering is quite different than an analog or traditional software EQ.

Operation of the Filter module is pretty straightforward -- select a node, set a shape, and drag up to increase the gain of the frequencies covered by that node, or drag down to cut the gain of those frequencies.

What you'll notice, however, is that you can create very non-traditional shapes with the Spectron Filter module. You're not limited to the typical "bell curves" of a parametric EQ. You can create squares, triangles, notches, curves, etc. They behave like traditional filters, but the don't have to look or sound like the old school EQs.

Filter Tips

1) You can use the "Mute Unprocessed" option to mute any frequencies except those under nodes. This allows you to create strangely shaped "bandpass" filters that highlight only specific frequency ranges.

2) The "Harmonics Only" is also an interesting option for boosting or cutting harmonics under a node. Try it with the "Mute Unprocessed" option to turn any signal into a harmonic sound, or try dropping the entire baseline of the Filter module (drag the 0 dB line down) and then boosting up only specific harmonics.

3) Since the Filter module allows "non-traditional" node shapes, you can create interesting effects by modulating with LFOs or envelopes the shape of a node. Instead of a traditional "sweeping frequency" filter, try sweeping the curve or shape of a node.

4) You can create incredible delay effects by using the Filter, Pan and Delay module while Spectron is patched as an insert effect on a track. You can control the Wet/Dry (delayed/not delayed) mix using your host app's send-return controls, and use the Filter, Pan and Delay modules to process the delayed effect. Delay some frequencies, pan others, sweep some filters across the whole thing. It can be a beautiful thing.
