Viiri Audio Aava - Modular Convolution Plugin With Real-Time IR Control
Quick Summary
Viiri Audio has released Aava, a creative convolution processor that lets you modulate impulse response parameters in real time - including start time, length, pitch, and timing - without glitches or crossfades. It landed May 18, 2026, priced at $79 intro until June 15, then $99. A fully functional 30-day trial is available with no email required.

Convolution has spent years doing one thing well: capturing spaces and printing them onto audio. Aava treats the impulse response itself as something you shape in real time, not just load and leave. That distinction is small on paper and significant in practice.
The core capability is glitch-free modulation of IR parameters during playback. Start time, length, pitch, and timing can all be automated or driven by modulators - LFO, envelope follower, AD/AR envelope, and key follow - at rates up to 100 Hz, which pushes into audio-rate territory. For drum and bass producers, the immediately practical entry point is Rhythmic mode: load a drum loop or amen break as the IR, sync its speed to host BPM, and use it to stamp rhythmic character onto reese basses, pads, or FX tails.
▸ Spec overview| IR layers | Up to 4, each with independent parameters |
|---|---|
| IR modes | Pitched (key-tracked) and Rhythmic (tempo-synced to host) |
| Modulation sources | LFO, S&H, AD/AR envelope, envelope follower, key follow |
| Explore Map | XY morph surface - interpolates between saved plugin state nodes |
| Spectral compressor | Single-knob, applied to wet signal only |
| Max IR length | 600 seconds; recordable from input, sidechain, or wet output |
| Formats | VST3, CLAP - Windows, macOS, Linux (no AU yet) |
| Pricing | $79 / £69 until June 15, 2026 - then $99 / £89 |
The Explore Map is what separates Aava from other creative convolution tools. Rather than stepping through presets, you save full plugin states as nodes and morph between them on an XY plane - useful for building evolving pad textures, slow-drifting reverb tails, or automated spatial transitions across a DnB arrangement without writing individual automation curves for every parameter.
One limitation worth flagging: AU is not included at launch. Logic Pro users will need a CLAP-to-AU bridge or need to wait for a native build, which the developer has said is on the roadmap. VST3 and CLAP are both present across Windows, macOS, and Linux.
For drum and bass producers: Rhythmic IR mode with host tempo sync is the fastest route in. Load a DnB break as the impulse response, automate the IR start time across your arrangement, and use the spectral compressor to control resonant buildup at low buffer sizes. The 30-day trial at viiri-audio.com needs no email address - worth an afternoon.
