Darkpalace Studio has launched a comprehensive collection of audio plugins based on the concept of allpass filters. The Chameleon Suite aims to unlock and empower you with creative flexibility and precision for your audio projects.

Allpass filters are one of the most fundamental building-blocks in the world of signal processing, and while they are not as popular or well-known as other types of filters, they play a crucial role when it comes to shaping sound and can be used to create almost all other filter types.

In general, an allpass filter is characterized by the fact that they pass through all frequencies without a change in level. This means that by themselves it is unable to shape frequencies one would normally do with a bell-, shelf-, notch- or any other type of filter.

They do, however, introduce a phase shift which can be used for other creative purposes. As the phase shift is frequency dependant, you can think of this as a frequency-dependant delay. Whereas standard delays delay the complete signal, an allpass filter delays different frequencies by different amounts of time.

Chameleon Suite features

  • Chameleon 1: First order allpass filter with frequency control.
  • Chameleon 2: Second order allpass filter with frequency and q controls.
  • Chameleon N: Nth order allpass filter with frequency, q and order controls.

Available for Windows, Mac and Linux (VST3, AU and CLAP), the plugin suite is priced 20 EUR.
