Two products, built without compromise.
Analog Realism keeps a deliberately small catalogue. Each release is engineered to be useful for years, not seasons. Sphinx 101 for the master bus, and Sphinx Channel for every track.
Sphinx 101
Master bus processor. Component-accurate analog modeling with TrueRail Technology. Three main circuits - SLL, Nevy, Amok - with thirty-four analog modeling mechanisms tuned to the harmonic and dynamic signatures of the modeled console classes. Added with known hardware circuits - Pultey, Nevy, SLL, Amok and Maney - for EQ, Filter and all Dynamic Modules.
Two skins. Different vibe.

01
Jiles-Atherton flux-integrated hysteresis
The core is driven by integrated flux (V/f law), producing frequency-dependent saturation that matches real iron.

On five Class-A device stages.
-
32
1/f noise spectral shaping

33
Channel-independent noise floors
Each channel draws its own noise stream while the stereo pair shares matched component tolerances, so the floor sums to mono and nulls the way two real devices do.
-
34
True Gaussian noise statistics
The modeled thermal floor carries the statistics of real thermal noise rather than a uniform digital approximation.

Specifications.
AU and VST3 on macOS 11 (Big Sur) or later - universal installers carry Apple Silicon (arm64) and Intel (x86_64) in one package, with single-architecture builds also available. VST3 on Windows 10 or later (x64). 4 GB RAM, approximately 50 MB disk.
Sample rates 44.1-192 kHz (verified identical character). Buffer 64-2048 (bit-identical output). Internal precision 64-bit. Oversampling 2× / 4× / 8× / 16× applied globally - one minimum-phase polyphase IIR half-band wraps the entire signal chain, every module runs at the elevated rate. The minimum-phase design eliminates pre-ringing; phase rotates monotonically with frequency, matching analog hardware. Noise floor produced by the component noise model; exact figures for every personality and topology combination are documented in the shipped Noise Verification test report. Per-element alias measurements documented in the shipped HF Alias Regression test report; full-chain Plugin-path alias measurements in the shipped Plugin-Path Alias Regression test report.
−6 dBFS = 0 VU. Bypass transparency bit-exact in steady state (zero residue; TrueRail chassis character only while enabled). Polarity non-inverting at all frequencies. Sample-accurate DAW latency compensation.
79 parameters, all automation-compatible. 34 TrueRail mechanisms. CPU: 3-10 % single-core at 2× on Apple Silicon. Authorization one-time, 2 seats per serial.
Sphinx Channel
Analog channel summing. A component-modeled input chain meant for every track - input transformer, discrete drive circuit, TrueRail power-supply grades, and a stereo width stage. Every instance connects to a shared virtual console frame: supply loading, mains-ripple phase, channel bleed, signal ground, and ambient heat are shared across the whole session, the way strips share one frame in a real console. A single instance always sounds like one channel; a full session gains the common electrical character of one desk.
Two skins. Different vibe.
-
01 - Nevy skin / default
-
02 - Amok skin / light metal
-
03 - Signal analysis
One strip per track. One console per session.
- The shared console - Sphinx Channel exclusive
- 01
Shared supply loading
Every instance's current draw sags the common rail that every other instance reads - a busy session breathes as one power supply.
- 02
Console-coherent mains ripple
All instances phase-lock their supply ripple to one shared console clock, summing the way strips in a single frame hum together.
- 03
Console channel bleed
Each strip contributes a calibrated share of adjacent-channel bleed, held at "one console" level no matter how many instances the session runs.
- 04
Shared ground-return coherence
The signed ground currents of all strips sum, with real cancellation, into each strip's ground-lift path.
- 05
Console ambient heat
The frame warms with the whole session's work, and every strip's thermal state feels it.
- Channel strip
- 06
Input transformer
Four core materials - M1166, C9049, K1166, L1544 - with full Jiles-Atherton hysteresis, remanence, and Bertotti dynamic core loss.
- 07
Three drive circuits
SLL push-pull BJT, Nevy single-ended Class-A, Amok 5670 triode - each changes the whole chain, not just the drive stage.
- 08
TrueRail grades A / B / C
Component-tolerance spread from factory spec to vintage wide. Same instance seed across tiers - switching widens or narrows the same variation pattern.
- 09
Width stage
-100 to +100 percent stereo width on a modeled tube line stage. Stays off on mono tracks.
- 10
ALL remote control
One button broadcasts knob changes, preset loads, window size, and skin to every Sphinx Channel in the session.
- 11
Per-instance tolerances & warm-up
Every instance draws unique component values from its seed and physically warms up in its first moments, like real hardware.

Sample rates 44.1-192 kHz (verified identical character). Buffer 64-2048 (bit-identical output). Internal precision 64-bit. Oversampling 2× / 4× / 8× / 16× applied globally - one minimum-phase polyphase IIR half-band wraps the entire signal chain, so every nonlinearity is anti-aliased by the same filter pair with no per-module latency mismatches.
−6 dBFS peak, where the nonlinear components produce their most musical harmonics; −18 dBFS RMS sits on the printed 0 VU mark. Bypass crossfades in ~12 ms, bit-exact in steady state. Polarity non-inverting at all frequencies. Sample-accurate DAW latency compensation.
All parameters automation-compatible except the oversampling selector. Window size remembered per instance, outside the parameter system. Signal flow: Input Gain → Input Transformer → Drive Stage → Width → Output, over the always-active TrueRail shared infrastructure. Authorization one-time, 2 seats per serial. Demo mode: 2-second silence approximately every 2 minutes, synchronized across unactivated instances.
