OXIDE

Dynamic Convolution Tape Engine

Twenty-four magnetic, cassette and early digital characters captured as level-dependent convolution. OXIDE changes with level, not just with a static impulse response.

00 / Overview

A tape engine that responds to the performance.

OXIDE is not a generic waveshaper with a tape label. Each model combines its linear frequency and phase response with level-dependent H2-H5 harmonic kernels. Drive harder and the magnetic character changes with the source.

01 / Installation

Install the engine and its authenticated library together.

macOS 13+ / Universal

Apple Silicon and Intel

The notarized DMG installs Audio Unit, VST3, the standalone application and the OXIDE kernel library.

  1. Close every DAW and plug-in host.
  2. Open the OXIDE distribution DMG.
  3. Run Install OXIDE Tape Engine.pkg.
  4. Rescan plug-ins or restart the host.

  2. Run the OXIDE setup as administrator.
  3. Complete the installer wizard.
  4. Rescan the VST3 folder in the host.
First launch

Wait for ready

Model preparation happens away from the audio callback. During loading, OXIDE outputs latency-aligned source audio instead of silence.

  1. Insert OXIDE on a mono or stereo track.
  2. Wait for NATIVE ENGINE READY.
  3. Choose a model and begin gain matching.
02 / Signal Flow

Level drives the model before the final blend.

The dry side is delayed to the same latency as the tape side. This keeps Source/Tape phase coherent and makes Bypass a meaningful comparison.

Input and Output are not interchangeable. Input changes which dynamic kernels are excited. Output changes only the final level. Match Output after setting Input so loudness does not make the processed signal seem automatically better.
03 / Controls

Seven controls, each with one clear job.

Tape Model

24 choices

Selects the complete linear and nonlinear machine profile. Model loading is prepared in the background.

Start with 30 IPS for focus, 15 IPS for weight and 7.5 IPS or cassette for obvious character.

Input / Drive

-24 to +24 dB

Sets the level entering the dynamic convolution engine. Higher values move the model into denser harmonic states.

Use Output to compensate after the desired density is reached.

Output

-24 to +24 dB

Applies clean gain after Source/Tape. It does not change the magnetic response or harmonic selection.

Level-match bypass before choosing between models.

Source / Tape

0 to 100%

Crossfades between latency-aligned source and processed tape. Zero is source; 100% is the complete tape path.

Parallel settings between 20% and 70% often preserve transient definition.

Harmonics

0 to 200%

Scales the level-dependent H2-H5 contribution without removing the selected model's H1 frequency and phase response.

Zero keeps the linear machine response; 100% is calibrated; values above 100% exaggerate colour.

Economy

On / Off

Uses H1-H3 and a bounded dynamic tail. The complete linear response remains active while H4-H5 are omitted.

Use Full for printing and mastering decisions; Economy for large sessions or tracking chains.

Bypass

On / Off

Returns the latency-aligned source path for honest comparisons without changing the timing seen by the host.

Compare at matched level, especially when Input is positive.

Magnetic Response

IN / OUT

The dual meter shows the current input and output peaks. The profile panel identifies era, format, speed and model character.

The meter is diagnostic; use your DAW meters for final loudness and true-peak decisions.
04 / Tape Library

Twenty-four distinct production characters.

Names describe the useful format, era and speed without relying on external machine branding. Search by model, speed, format or character.

05 / Workflows

Choose speed first, then drive, then colour.

Master bus cohesion

Start with a stereo 30 IPS model. Add only enough Input to make peaks sit together, then match Output precisely.

Input +1 to +3 dBTape 70-100%Harmonics 60-100%Full

Drum bus density

Use a 15 IPS multitrack profile for body or 30 IPS for harder attacks. Parallel blend keeps the front edge intact.

Input +3 to +7 dBTape 55-85%Harmonics 100-140%Full

Bass weight

Start at 15 IPS. If the fundamental becomes too broad, switch to the matching 30 IPS model before reducing drive.

Input +2 to +5 dBTape 70-100%Harmonics 70-110%Output match

Vocals and instruments

A 30 IPS tracking model adds density with less head bump. Lower Harmonics when sibilance or bow texture becomes forward.

Input +1 to +4 dBTape 40-75%Harmonics 50-100%Economy optional

Parallel tape return

Drive the engine harder and reduce Source/Tape. This exposes harmonic texture while keeping the original transient path.

Input +5 to +10 dBTape 15-40%Harmonics 100-160%Output match

Lo-fi statement

Choose a cassette or low-speed model. Use Harmonics above calibration only after deciding how much top-end softening the model should retain.

Input +6 to +12 dBTape 80-100%Harmonics 120-180%Full
06 / Technical

Native processing with explicit host timing.

Latency

At 48 kHz OXIDE reports 388 samples, or 8.083 ms. The dry path is internally aligned to the processed path.

Full engine

Evaluates H1-H5 with level interpolation across the captured dynamic states.

Economy engine

Evaluates H1-H3, preserves the complete H1 response and bounds the dynamic tail for lower CPU use.

Sample rates

The production kernels are converted to the active host rate during model loading. No manual SRC setting is required.

Channel layouts

Native mono and stereo layouts are supported. Mono sessions process one active audio channel.

Resource integrity

The production library is encrypted and authenticated. Modified, truncated or incompatible resources are rejected before use.

OXIDE is a colour processor, not a limiter. Leave enough headroom after Output and use a true-peak meter later in the chain when mastering.
07 / Troubleshooting

Read the status before changing the mix.

StatusMeaningAction
NATIVE ENGINE READYThe selected model is prepared and active.No action required.
LOADING MODELA new model or sample-rate version is being prepared.Wait briefly; aligned source audio continues.
KERNEL LIBRARY NOT FOUNDThe authenticated model library is missing from its installed location.Close the host and rerun the complete installer.
MODEL LOAD FAILEDThe model resource is incomplete, incompatible or failed authentication.Reinstall OXIDE. Do not move individual kernel files.
ENGINE IDLEThe audio device or host processing graph has not prepared the plug-in.Start transport, enable the track or reopen the audio device.
Every model sounds identical

Confirm that the status reads NATIVE ENGINE READY after each selection. Set Source/Tape to 100%, Harmonics to 100% and use a moderate positive Input value while comparing. If the status reports a library error, rerun the complete installer.

The plug-in is louder, but I cannot judge the colour

Lower Output until bypass and processed loudness are closely matched. Input changes the dynamic response, so do not compensate by reducing Input unless the saturation itself is excessive.

Economy sounds slightly less complex

This is expected. Economy keeps H1-H3 and omits H4-H5. Use Full when upper-order texture matters, especially for exposed buses, mastering and final printing.

The host reports latency

OXIDE intentionally reports its partitioned convolution latency. At 48 kHz this is 388 samples. Keep plug-in delay compensation enabled in the DAW.

The model changes a moment after selection

Model preparation occurs off the audio callback, then the completed model is atomically published and crossfaded. This avoids blocking the real-time audio thread.
