Oxidex

Analog Tape Saturation

"Analog tape saturation modeling real reel-to-reel behavior — magnetic hysteresis engine, three IPS tape speeds, wear texture, and tape stop performance control."

Oxidex models the physics of real reel-to-reel tape — magnetic hysteresis, resonant head bump, wow and flutter, and spectral wear — so you can dial anything from a pristine studio reel to a crinkled attic cassette. A single Wear knob ages the tape, Transient Snap keeps drum attacks alive through heavy drive, and Auto Gain strips away the louder-is-better bias so you hear character, not volume. Signed and notarized on macOS, code-signed on Windows. AU, VST3, CLAP, AAX and Standalone on macOS; VST3, CLAP and Standalone on Windows.

FEATURES

Saturation Engine

◆Magnetic hysteresis model — frequency-dependent saturation matching real tape oxide behavior, with heavier low-frequency saturation
◆Oversampled S-curve saturation: Draft (2x), Standard (4x), HQ (8x) via polyphase IIR oversamplers
◆DC Bias for even-harmonic generation — warm tube-like character from asymmetric clipping
◆Three tape speeds: 7.5 IPS (vintage warmth), 15 IPS (classic studio), 30 IPS (hi-fi modern) — each with distinct rolloff, head bump, and drive character

Tone & Texture

◆ZDF/TPT head bump — phase-consistent sub-bass boost up to +8 dB at the tape-speed-dependent center frequency
◆Tilt EQ — single-knob tone control pivoting at 1kHz for darkening or brightening
◆Transient Snap — envelope-based detector that recovers kick and snare attacks through heavy drive
◆Wear — single knob combining wow & flutter, spectral degradation, and probabilistic tape dropouts

Performance Controls

◆Tape Stop — physics-based slowdown and spin-up with quadratic friction curve, Lagrange-interpolated playback
◆Motor Pressure — momentary hold: flanger + 4x drive boost + 200 Hz HP filter for industrial buildup effects
◆Tape hiss with White and Brownian color modes, stereo decorrelation, and silence gate
◆Inter-channel crosstalk at −40 dB simulating adjacent-track bleed on multi-track machines

Output & Monitoring

◆Auto gain matching with ~100ms RMS smoothing removes louder-is-better bias
◆Drive-Output LINK coupling for pure character A/B comparison
◆Flux Meter display with bloom, heat, and core rendering layers — waveform amplitude compresses visually with saturation
◆22 factory presets, A/B comparison, Randomize, and preset save/load

FREQUENTLY ASKED QUESTIONS

How much does Oxidex cost?

Oxidex is pay-what-you-want with a $5 floor, a one-time purchase. If you want to try the engine first, Oxidex Raw gives you the essentials behind one knob.

Does Oxidex run on Apple Silicon and Windows?

Yes. Oxidex is a Universal Binary that runs natively on Apple Silicon (M1/M2/M3/M4) and Intel Macs, and it also ships as a 64-bit build for Windows 10 and 11.

Which formats and systems does Oxidex support?

AU, VST3, CLAP, AAX and a Standalone app on macOS 15.0 or later, as a Universal Binary for Apple Silicon and Intel Macs. VST3, CLAP and a Standalone app on Windows 10 and 11, 64-bit. AAX ships on macOS only.

How do I install Oxidex?

On macOS, double-click the .pkg installer and follow the prompts; it installs every format at once. On Windows, run the .exe installer. The macOS build is code-signed and notarized by Apple and the Windows build is Authenticode signed, so neither needs a security override. No dongle and no extra account.

How is Oxidex different from Oxidex Raw?

Oxidex Raw is the one-knob version: the same engine behind a single macro, with the detailed controls hidden. Oxidex gives you the full control set.
