ACQUA - Ultramarine3

ULTRAMARINE3 is a VST/AAX/AU plug-in which faithfully emulates a vintage vacuum-tube dynamic processor designed in the early '50s and universally considered the most coveted compressor of all time.
The first purpose behind the creation of ULTRAMARINE3 was to "bridle" the sound of a rare machine; yet, at the same time, we wanted to extend its operation far beyond the technological boundaries of its time and, thanks to Acustica's proprietary technology, create a modern object capable of shaping the sound in new ways as well, all the while preserving every sonic detail of its unique 'magic'.
It was quite a tough mission, but we are extremely happy with the outcome!


Today, after all the work and passion we have poured into this project, we at Acustica feel very proud for this release. ULTRAMARINE3 is different from any other plugin you have ever used; it's a very versatile tool capable of providing a lot of old and new musical ways to shape your sound, with the help of a gorgeous graphical user interface.

One of the exciting new features that we introduced in ULTRAMARINE3 for the first time is “ShMod”. It's a shape control for the attack stage of the compressor which allows you to fine-tune the attack curve and adapt it to any audio source.  
Another innovative feature that greatly increases the versatility of this compressor is the continuously variable SC (Side-chain) Filter. This control allows you to determine how much low-frequency content is hitting the detector stage in the compressor.
Finally, ULTRAMARINE3 is equipped with a DRY/WET control that allows setting the balance between the dry and wet signal.


  • Variable speeds on vector nodes improving the sound quality of the compressors and allowing to reach very fast speeds and precision.
  • Envelope followers based on control sources.
  • Queue messages used for several widgets like knobs improving the behavior, control, and stability of plug-ins.
  • Hidden components fault-tolerant inside nebula/acqua engine to minimized crash/bugs.
  • New wrapper to get better-balanced AAX format
  • Several minor fixes and improvements (about trimming, sample rate conversion, distribution of sample rate packs, fixes on loaded program rate).
  • This engine is linked to Nat4 to allows the full automatic compressor sampling.
  • Switchmode optimization reducing CPU loading
  • Lazy loading pattern introduced to improve the loading of the objects
