Signal Generator Controls
Frequency Sets the frequency of the signal in
hertz. Values range from a low of 20 Hz to a
high of 20 kHz in a 44.1 kHz session. The upper
limit of the frequency range for this setting will
increase to match the
Nyquist frequency (half the
sample rate) in 96 kHz and 192 kHz sessions
(HD-series systems only).
Level Sets the amplitude of the signal in deci-
bels. Values range from a low of –95 dB to a high
of 0.0 dB.
Signal These buttons select the waveform.
Choices are sine, square, sawtooth, triangle,
white noise, and pink noise.
Peak
Generates signal at the maximum possible
level without clipping.
RMS
Generates signal at levels consistent with
the RMS (Root-Mean-Square) value, or the effec-
tive average level of the signal.
SignalTools
DigiRack SignalTools metering plug-ins provide
two metering modules: SurroundScope and
PhaseScope.
The SignalTools plug-ins support TDM and
RTAS plug-in formats at all sample rates.
SurroundScope
(Pro Tools HD Only)
SurroundScope is a plug-in that provides sur-
round metering for multichannel track types
from 3 channels (LCR) to 8 channels (7.1 sur-
round). Stereo and mono tracks are not sup-
ported.
The Signal Generator plug-in is not in-
tended for rigorous test purposes; it is a sim-
ple level calibration tool.
This version of SurroundScope is compatible
with sessions that used the previous ver-
sions of SurroundScope.
