DSP Delay

The delay incurred by any of the Chrome Tone plug-In congurations is ZERO

samples. On HD systems the delay is 1 (ONE) sample. There is still a two sample

delay from the TDM connection to the Chrome Tone plug-In. This is the absolute

minimum number of delay samples a TDM plug-In can have. The McDSP plug-Ins

are designed in this manner to provide the user with the closest analog mixing

console experience possible (analog inserts such as EQ and compression do not

cause a processing delay when inserted into a track).

DSP Usage

HD, and HD Accel DSP hardware

The TDM versions of the Chrome Tone plug-in congurations use a varying

amount of dsp resources for each Chrome Tone conguration. The table below

is a listing of these dsp usages. The DSP Allocator utility provided by Digidesign

™ (or the DSP Usage display in ProTools ™ for PT version 6.2.3 and later) may be

used to display dsp resource allocation when ProTools ™ is running.
