questions.

Yes. Free for personal and commercial music production, with no time limit, no watermark, and no nag screen.

If Arna ends up on a commercial release, credit is appreciated and never required.

Full is paid. Pricing isn't fixed yet but the target is in the same range as boutique algorithmic reverbs from small developers — expect somewhere between USD 79 and USD 149.

Ship date: we are not announcing one until it's behind us. Get on the list at hi@1snob.com to be first.

The 1snob edition is unrestricted — install on as many machines as you own. The Full edition will use a single-user licence with offline activation across two machines (your studio and your laptop).

VST3 and Audio Unit (AU). Both are Universal — Apple Silicon and Intel — in a single bundle.

Pro Tools (AAX) is on the wishlist. Not committed to a date.

Not at launch. Arna is built on JUCE 8 and the engine is portable, but the validation gate (pluginval Level 10, ctest, torture battery) runs on macOS only at the moment.

Windows is on the wishlist after Full ships. If you're a Windows producer who would buy it the day it lands, please tell us — that signal moves the priority.

No, and it isn't planned. JUCE supports Linux but the user base in our target audience is small enough that it isn't pulling its weight against a Windows build.

Differentiable Geometric Feedback Delay Network. A reverb topology where the routing is geometric (rooms model real spatial behaviour) and the parameters are differentiable, so we can train them end-to-end against target impulse responses.

In practice: the knobs map onto interpretable audio parameters (decay time, density, modulation depth) but the network behind them was tuned by gradient descent against a corpus of measured impulse responses, not by guessing.

Sample rates: 44.1, 48, 88.2, 96, 176.4, 192 kHz. The internal network always runs at the host rate — no oversampling, no internal SRC.

Block sizes: 32 to 2048 samples. Validated at 32, 64, 128, 256, 512, 1024, and 2048. Any host-supplied block size in the range will work.

Zero added. Arna does not look ahead. The reported plugin latency is 0 samples, so PDC won't kick in.

No. The engine is fully real-time — no allocations, no locks, no syscalls inside processBlock. Validated through the internal torture battery and pluginval Level 10.

On an M1 Pro at 48 kHz with a 256-sample buffer, a single instance of Arna 1snob takes roughly 0.6% of one CPU. Full mode with all nine knobs active is around 1.1%. Linear with channel count.

Two colours that survive bad monitors, on-stage lights, and screenshots. Cream is the universal "lit" signal — text, the active pill, the selected preset, scrollbar thumbs. Orange is the field everything sits on.

The two cold colours in the system — iceBlue for Freeze, coral for destructive actions — are earned. Never decorative. iceBlue means the network is at unity feedback. Coral means a click will erase your state.

Because most reverbs need most of their controls in opposite directions to anything sensible. If a small change to Decay implies a small change to Density and Tone, the user shouldn't have to make those changes in three places.

The one knob is also a constraint that forces the design honest. If a phase doesn't deliver a real sound, removing it is obvious. The five anchors of the journey are the only ones that earned their seat.

After Arna Vyborova, a fictional luthier from a story Leandro tells about himself. The plugin is a small instrument — built by hand, intended to be turned, not configured.
