Acustica Audio has released Purple3. The latest version of the Pultec-themed plug-in suite includes Purple3-HLF, a new passive high and low pass filter. All Purple3 plug-ins now run on Acustica’s newest Core 15 engine.

Less than two weeks after Coffee, Acustica has already got the next release ready. This time, it’s more of a technical update to modernize the company’s Pultec EQ collection and upgrade it to the new Core 15 engine. But Acustica has also added another plug-in to the suite, which now includes six individual EQs and filters. All of them are Pultec-themed and have been derived from various hardware units using Acustica’s sampling-based process.

The Purple3-HLF is the new addition to the suite. The plug-in features a passive 12 dB/oct. high and low cut filter which Acustica describes as “singing”. It also includes a preamp section derived from the Purple3-P1. Acustica claims that the filter delivers musical results and lends itself to tonal sculpting, special effects and corrective tasks like hum or hiss removal.

The rest of the suite hasn’t changed (on the surface) and is still made up of the following plug-ins:

  • P-1 (Vintage tube-based, passive program Equalizer)
  • P-AA (Tube-based passive program Equalizer reissue)
  • M-5 (Classic mid range tube EQ)
  • M-5V (Vintage classic mid range tube EQ)
  • H2 (Vintage single channel tube EQ)

They all run on the Core 15 engine now, which includes EHR (Enhanced Harmonic Response Technology) and Dynamic Routing. Each plug-in comes in standard and zero-latency versions.


I’m glad that Acustica isn’t forgetting about its essential plug-in collections like Purple amidst all the new releases. The Pultecs are go-to EQs for many producers, so it’s good to see Acustica doing some maintenance.

Price and compatibility

Purple3 is on sale at 65% off during the introductory period. During the first four weeks, you can get it for EUR 69 instead of EUR 199.

The plug-ins run on Windows 10 or higher and macOS 10.14 or higher in VST, AU and AAX formats. The installation and activation process is handled by the Aquarius application, which also lets you download and install a trial version.
