Pataki Audio releases Janus, MetaHost, Voicing and Bitscope (VST3; macOS & Windows; Free/Donationware)

Pataki Audio, a one-person workshop based in Budapest, has released four new VST3 plugins. Janus Janus is a linear-phase Linkwitz-Riley crossover VST3 plugin for Windows and macOS. Janus combines a high-pass and a low-pass filter on a single instance, with a symmetric FIR design.

Two instances tuned to the same cutoff frequency sum mathematically flat, making it suited for multi-way active loudspeakers where phase coherence between bands and minimized audible pre-ringing are both critical. Janus offers Linkwitz-Riley slopes from 1 to 48 dB/oct in decimal steps — not just the conventional 12 / 24 / 48 — letting you tune the crossover region precisely without committing to a fixed Butterworth order. Three latency modes (Eco / Normal / High-Res) let you trade pre-ringing against processing latency depending on the source material.

Janus is donationware. Pay what you want, including nothing. No ads, no telemetry, no nag screens.

MetaHost MetaHost is a VST3 plugin host that you load inside another VST3 host, for Windows and macOS. MetaHost offers 8 stereo channel-pair columns with 3 plugin slot rows per column, letting you drop a different plugin chain on each stereo pair of a multichannel bus. It's designed for active speaker rigs running per-driver DSP, surround / Atmos mixers needing per-channel processing, stereo workflows with parallel effect chains, and any setup where the host DAW won't let you route inserts the way you actually need to.

Each hosted plugin's UI opens in its own floating, resizable editor window — no nested frames or clipping. Full host state, including each hosted plugin's preset, can be saved to disk or inlined into the parent project for exact-recall sessions. Per-slot bypass is implemented with atomic flags for click-free, thread-safe switching during playback.

Unlike a surgical measurement EQ, Voicing is designed to tilt rather than carve: its shelves are gentle, broad, and intentionally reciprocal, so cut and boost behave as mirrored halves of the same adjustment. The shelves taper toward an asymptote at the extremes, keeping even bold settings musical, while the parametric bell spans wide tonal lean to focused presence shaping. Voicing offers a low shelf and high shelf with adjustable slopes — from a gentle first-order 6 dB/oct upward — a parametric bell with adjustable Q, and per-band enable for instant A/B comparison.

It's positioned as the listener-end companion to Pataki Audio's linear-phase crossover, Janus. Voicing is donationware. Pay what you want, including nothing.

No ads, no telemetry. Bitscope Bitscope is a bit-depth and true-peak analyzer VST3 plugin for Windows and macOS. Bitscope measures the effective bit-depth of audio in real time — the bits actually doing useful work, not just the claimed format — displayed as a per-channel histogram up to 64-bit.

It tracks true-peak level in dBTP and keeps separate counters for sample clips and intersample peaks, catching the inter-sample overs that standard sample-peak meters miss. The plugin is multichannel-aware: its L/R source selectors pick any two channels from the host bus for monitoring, with a readout showing the host-bus channel count and layout. Bitscope is analysis-only — it measures the signal without altering it.
