Plinth Subharmonic Synthesizer reports zero samples of plugin latency, yet its generated sub reaches 90 percent level after roughly seven source cycles. Those statements can both be true because DAW latency and pitch-tracking onset describe different things. One concerns when the plugin returns audio to the host, while the other concerns how long the detector needs to trust what it is hearing.
That difference matters most on low notes, where each waveform cycle already lasts a noticeable amount of time. Seven cycles at 80 Hz take about 88 milliseconds, while seven cycles at 40 Hz take about 175 milliseconds. The host still sees zero samples of delay compensation, but the new sub voice cannot fully establish itself before the detector has observed enough periodic information.
The Vitric Audio Studio 4 release lineup places Plinth among eleven processors, but the useful detail here is its tracking behavior rather than the wider launch. Plinth detects fundamentals through a filtered mono sidechain, leaves the dry path untouched, and generates up to three phase-locked sub voices on one centered mono bus.
On a steady bass guitar note, that delay may simply feel like the generated weight settling under the attack. A short kick is different because much of its identity can happen before seven low-frequency cycles have passed. You can therefore have a technically zero-latency plugin whose synthetic low end develops later than the dry transient, without any contradiction in the specification.
This is where phase-locked sub generation becomes more useful than a generic promise of bigger bass. Vitric reports no measurable phase drift against an 80 Hz reference over 60 seconds once Plinth is locked, with correction limited to 10 degrees per cycle. The practical goal is not instant detection, but a generated voice that stops wandering against the source after detection has settled.
That behavior changes how you can place a subharmonic generator on mixed or imperfect material. The processor is not supposed to emit a low burble merely because something energetic entered the detector, and its dry signal never passes through that detection path. If the material becomes sufficiently periodic, the voice can open after confidence builds.
Octave errors get their own protection. A source with a weak fundamental and a strong second harmonic can tempt a tracker into following the wrong octave, so Plinth uses hysteresis before changing its decision. Vitric says its octave-trap test produced zero flips and requires about 64 milliseconds of persistent evidence before the detector moves to another octave.
The generated sub remains mono and centered even when the input is stereo. Vitric reports bit-identical left and right sub contributions from decorrelated stereo program material, which prevents the synthesized deepest layer from becoming a moving stereo event. The original dry path remains separate, so stereo information above it is not collapsed by the detector.
Blend at 100 percent puts the generated sub at level with the dry low band by volume rather than using compression, ducking or automatic makeup gain. That matters on an 808 or sustained synth bass because the processor is not secretly reshaping the source envelope to create space for its own output. You hear the tracked voice arrive, remain phase-locked, and leave again according to the detector's confidence and the source itself.

Zero latency still leaves tracking time
Subharmonic generators create new information below the source instead of merely boosting bass that already exists. That means a tracking design has to decide which periodic component represents the musical fundamental before it can generate a stable lower voice. Plinth smooths detection confidence for about 30 milliseconds before a voice is allowed to open, then takes about seven cycles to reach 90 percent onset.On a steady bass guitar note, that delay may simply feel like the generated weight settling under the attack.

Silence on noise keeps the detector disciplined
Pitch tracking can fail badly when a processor treats every burst of energy as evidence of a note. A snare tail, distorted texture or noisy room signal may contain plenty of low-frequency energy without presenting a stable fundamental worth following. Plinth is designed to leave the sub bus at exact digital silence on its pink-noise test rather than guessing.That behavior changes how you can place a subharmonic generator on mixed or imperfect material.

Manual override handles the cases tracking cannot
Automatic fundamental tracking works best when the source contains a reasonably stable pitch, which is not every low-end job. Plinth includes an Override control that lets you pin the detection frequency manually, useful when the source is ambiguous or when you want the generated bass tied to a chosen frequency rather than the detector's current interpretation. The display follows that pinned value so the operating state stays visible.The generated sub remains mono and centered even when the input is stereo.
