BetabugsAudio have released Crayon Filter, their second freeware VST plug-in for the Windows platform.

Crayon Filter is a simple to use multi-band filter plug-in that is controllable with MIDI CC, and fully supports the VST 2.3 standard. It comes in three flavours: a non-installer, an installer and a source code version.

You can engage up to five filter types at once (one of each type):

• Low Pass attenuates high frequencies, giving your sound a "dull" feel.
• Band Pass attenuates both above and below the cutoff frequency, for a "thin" or "nasal" sound.
• High Pass removes low frequency signals.
• Notch removes just a small band of frequencies from the signal.
• Peak boosts a small band of frequencies in your audio.
