PARIS and Native Plug-in Latency
"Latency" is the time delay a plugin or other process introduces into an audio stream. Some plugins process in "real time" whereas others introduce either imperceptible or audible delay into the audio stream. This can create problems from disrupting internal phase relationships in multi-mic audio all the way to perceptibly "dragging" a track's timing.
The PARIS app, last updated in 2001, lacks internal latency compensation for either native or internal plugins, so PARIS users have evolved a variety of workarounds. They can avoid the issue by avoiding plugins that introduce latency; manually compensate for latency by nudging or sliding audio on the edit screen; or compensate for latency within a given submix via a system such as Vertex DSP's FaderWorks. Those who want to avoid the issue altogether can avoid the plugins marked in red below. Those seeking to manually compensate for latency can look up the exact latency of any particular plugin and nudge their audio earlier by that amount (or all other audio later by that amount). See important notes in sidebar to right for considerations affecting this approach.
Thanks to the efforts of user Dimitrios, PARIS users gained a new more convenient option for relative latency compensation for native plugins in 2009. Vertex DSP's FaderWorks uses a clever approach to compensate for global latency. A FaderWorks plugin is inserted on each channel of the PARIS mixer; FaderWorks keeps track of the latencies of each new plugin and delays all other channels in the submix accordingly if necessary. FaderWorks is not full global latency compensation - that particular submix will be delayed in relation to other submixes (latency is a "delay" of audio, so the ideal solution to correct for it would be to "advance" that audio in time, but FaderWorks can only affect audio that has already passed through the native inserts - it can't play audio any earlier than it receives it). But it's a great solution to correct *relative* latencies between channels within submixes. Delays are cumulative per channel; however, the maximum overall delay FaderWorks will introduce in a submix will be that of the most "latent" channel. Unless you're using highly "latent" plugins (or many native plugins with smaller latencies in series on a single channel), you may not notice any perceptible delay.
Note that when you are "nudging" on the editor screen in PARIS, the "nudge" values are not precise. PARIS power-user DJ explains in depth: "The nudge values are not consistent with what one would expect the samples to be per ms, and they are also not consistent with themselves. Meaning that a 1ms nudge would be expected to be 44 samples [assuming a sample rate of 44.1k] but is actually 80. A 10ms nudge isn't 10 X 80 or 800 samples though, it's actually 480."
DJ: "Using sampleslide to assist the nudge function... for UAD-1 plugins, Sampleslide presets were as follows:"
| Displayed Value | Actual movement in editor |
|---|---|
| "1ms" | 80 samples |
| "5ms" | 240 samples |
| "10ms" | 480 samples |
| "25ms" | 1120 samples |
| "50ms" | 2240 samples |
| "75ms" | 3360 samples |
| "100ms" | 4480 samples |
