Audiority has released a maintenance update for the Polaris audio effect, an echo/reverb plugin inspired by early hardware digital reverbs of the late 1970s.

Polaris provides echo, ambience and reverb out of a single multitap delay line.

When hardware digital reverbs came out to the market they were really expensive. Most manufacturers were already exploiting chains of comb and allpass filters (smoother reverbs, but expensive in both resources and chips), there were other techniques involving the use of a single multitap delay line to create a reasonable reverb while keeping the cost affordable.

That idea is so simple yet powerful: you mix a bunch of unmodulated taps (Early Reflections) with the remaining modulated taps (Diffusion) to create a cheap but convincing reverb.

We extended this technique by making the Echo tap recirculating with the Diffusion section, allowing longer reverb tails. Furthermore you can easily edit all taps to create your own room responses, resonant combs, Karplus-like tuned delay lines, Chorus, Flanging, Vibrato and much more.

Changes in Polaris v1.7.1

  • Fixed: Wrong VST3 category.
  • Fixed: HQ button state not stored in session data.
  • Fixed: HQ resetting parameters to default value.
  • Fixed: Modulation causing noise in delay line.
  • Fixed: Silence triggered randomly in some configurations (Demo stutters).
  • Fixed: Newsfeed can now be disabled in Settings menu.

Polaris costs 45 EUR. It is available from Audiority and distributor Plugin Boutique.
