SIR3 now comes with 33 excellent HDIR models made by Pinguin Ingenieurbüro from Hamburg. The models are known for their high dynamic range and their exact natural fidelity.

Years of experience in developing audio plug-ins allowed us to take this product to a new level. The new SIR3 has been improved in almost every aspect. The very flexible modulation section allows you transform certain parts (head or tail section) in the time domain. It contains a multi-stage delay with random pitch modulation and random amplitude modulation in the feedback path.

Transform the audio signal with a rich set of dynamic processing opportunities like gating and ducking. Now you can do things like gated reverberation, or ducking the wet signal with the dry signal, directly inside the plugin.

In addition, the possibilities of envelope processing were further expanded. Use a Volume, Low-Pass, High-Pass, Width and Pan-Envelope to modify the impulse in a natural or creative way.

Furthermore, the software works with very low CPU consumption and zero-latency processing.
