Latency when it matters.
Many processors offer an Exact mode and a lower-latency monitoring mode. The lower-latency path can change phase or timing, so the mode is a sound choice as well as a workflow choice.

THE CURRENT EQ PLUG-IN. THE APP IN USE.
MEET MASTERING LAB
Mastering Lab brings the 23 Clios processors to iPhone and Mac. Import one mixed track for mastering, or multiple stems for mixing with a rack on each track and another on the master. Compare original and processed audio, inspect loudness and true peak, then export a WAV.
The app and plug-ins are in development. Captures come from working builds.

The desktop processors and Mastering Lab share their audio engines. The app brings those tools into Master and Mix workflows with A/B listening and export.
Clios Rack hosts other AU and VST3 effects inside serial, parallel and nested split paths. Its frequency splits can favor zero added latency or linear phase.

Soft peak clipper
Trims the highest transients before the mastering limiters. Depth sets how much is clipped; Softness changes the transition from clean signal to clipping.
What it adds Learn can set the clip reference from the incoming peak, so a small amount of clipping is easier to target.

Loudness enhancer
Raises perceived density through controlled waveshaping without using a conventional compressor. Effect and Curve set the strength and shape of the change.
What it adds A subtle lift ahead of the final maximizer; waveform and harmonic views make the change visible.

Mastering maximizer
Builds overall level with Gain, Output and Character controls. Balanced and Clipping modes offer different ways to handle peaks.
What it adds Designed as the main loudness stage before the final true-peak limiter, with reduction shown in the interface.

True-peak limiter
The last dynamics stage catches inter-sample peaks and sets the final output ceiling. Lookahead and transient/release linking shape its response.
What it adds Separates final peak control from the earlier maximizer, so loudness and output ceiling can be adjusted independently.

Mid/Side mastering glue compressor
A restrained compressor for joining a mix without flattening its movement. It offers L/R or Mid/Side operation, a reduction limit, link control, mix and gain matching.
What it adds The reduction limit makes small mastering moves easier to keep small, particularly when Mid and Side need different amounts of control.

Bus compressor
Compresses a drum group or full bus with threshold, ratio, attack, release, makeup and mix. A sidechain high-pass keeps bass from driving the detector too strongly.
What it adds Longer attack and shorter release settings can retain the front of a drum hit while tightening the group.

Tube compressor
Combines compression and tube character, with input, threshold, attack, release, detector filter, makeup and dry/wet controls.
What it adds A smoother second compression stage for vocals after fast peak control; the detector filter reduces the influence of low energy.

De-esser
Reduces harsh consonants only when energy rises inside the chosen detection range. Threshold, Range, Wide/Split band mode, lookahead and mix define the response.
What it adds The reduction trace and spectrum show when and where de-essing is working, helping avoid a permanently dark vocal.

FET compressor
Catches vocal or drum peaks with fast attack and release. Ratio, circuit revision, input/output and Mix cover firm peak control through parallel compression.
What it adds Two revision choices and a reduction trace make its punchy behavior easier to shape and inspect.

Opto compressor
Levels a vocal or group with Peak Reduction and Gain, plus Compress/Limit mode, Emphasis and Mix.
What it adds A slower, smoother dynamics option after a fast compressor when a source needs steady presence.

Multiband dynamics
Builds frequency-selective dynamics bands with their own range, threshold, ratio, knee and timing. Bands can compress or expand and can work in Mid/Side.
What it adds Can tame one frequency region or bring up another without making the whole mix follow one detector.

Resonance suppressor
Finds narrow resonances and reduces them when they appear, rather than leaving a permanent EQ cut. Depth, Sharpness, Selectivity, timing and frequency limits control the search.
What it adds Soft and Hard modes plus Mid-only focus the treatment; the display shows where reduction occurs. Its algorithm is still being tuned.
