iZotope Iris offers a new concept in sound design and sample manipulation in the form of a "visual instrument.".

Powered by iZotope's visual feedback technology, Iris lets you unearth a world of sounds you've never heard before. Delve into Iris's spectrogram to extract, layer, manipulate, and discover new sounds from within any audio file. With extended synthesis features, hundreds of presets, and 4 GB of source material, Iris is an impressive tool for sound design, musical inspiration, and sonic experimentation.

Create and discover musical sounds that have never been heard before. An inspiring sample-based synthesizer, Iris 2 is immediately playable—combining the power of a sampler, the flexibility of a modular synth, and the fun of spectral filtering.

Get started fast by selecting from hundreds of expertly crafted Bass, Keys, Leads, Pads, and Rhythmic patches. Then customize or build your own patches with an 11 GB factory library of intriguing audio samples, a modern modulation system, classic filters, evocative effects, and more. Explore a new world of musical possibilities with Iris 2.

Iris Key Features:

  • Discover what's hidden: Bring any audio file into Iris and isolate the most interesting spectral portions with a comprehensive set of easy-to-use selection tools. Play your completely custom sound instantly from any MIDI controller.
  • Become a mad sonic scientist: Create new textures and dramatic soundscapes by layering multiple sounds from similar or completely diverse audio sources.
  • Stay musical: Rely on intelligent root note detection to help shape musical material from noise, ambient textures, and soundscapes, then use advanced controls to tweak, modulate, and add effects to taste—all powered by iZotope's DSP.
  • Start playing immediately: A world of sound design is at your fingertips, with hundreds of presets from world-class sound designers and 4 GB of audio samples, including recordings of insects, animals, machines, vintage synthesizers, musical instruments and much more.

hmm, i use a early 2010 MacBookPro 6,1 (with orig. Samsung 830 SSD and i7 CPU, 8GB - with samples stored on a "fast" external firewire hard disk) and did not reached the system limits with Iris 2 so far, but mainly used Iris waves in the samples.

There are other products from iZotope which grabbing much more system Ressources like Breaktweaker if runned faster then 48 kHz for me, requiring track bouncing often in my projects with higher track counts and resolution.

But getting such computation without lack of fidelity typically costs large CPU (and partly bus) ressources - even if the critical code got optimized for that type of CPU. If your CPU did not offer a fast and capacitive variant of the cpu/math features the software relys on this could result in a significant performance loss. So having a modern workstation CPU is important if you want to run professional audio processors.

IRIS 2 does feel like a tool that plays samples with basic loop functionality and applies effects and modulation. The spectrum analyser window is helpful but is best left tucked away to reduce CPU load.

The spectral filtering window is the core of Iris, that's what it's all about, if you tuck it away and don't use it, you have totally missed the point of Iris. Using it as a sample player of course will only yield frustration due to the limitations, it's made for spectral resynthesis/filtering, nothing else.

I'll stick to creating within the limitations of the software or hardware. Usually the case in additive synthesis. One can't get frustrated when using a machete to shape a block of wood, because one decided to use it.

Yeah, so now i just reduce the release times and polyphony, use shorter samples and single cycle wave forms, hand draw wave forms and paste them together in external editor. import these into Iris2 scrape out some frequencies in the loops. Spectrum window is useful but was hoping it opens out to a separate window with options for zoom and x-y axis. Since we're using a spectrum analyser, maybe the ability to specify frequencies and Q factors in the filters/tools would be really helpful. Multiple loop points and the ability to change the sequence of these loops for each loaded audio would be appreciated. The visuals are aids, but we still create sounds by hearing and feeling them, adjusting the frequencies and amplitudes that affect that experience. A request for finer control for a better sound. Howz about it Izotope?
