Oversampled Clip Events Browser
The Oversampled Clip Events browser displays
historical clip events from the DSP oversam-
pling of the session audio. The amount of po-
tential clipping in excess of 0 dB is also dis-
played.
The columns displayed show the relevant time-
code for the beginning and ending of a clip
event, as well as the minimum and maximum
clip values created after passing through the DSP
processing. When used in a stereo track, the first
column shows L or R to indicate if the left or
right channel has clipped. The contents of this
browser can be sorted in ascending and de-
scending order by any column simply by click-
ing on the desired column one or more times.
The time information displayed in this browser
is relative to where the transport started. The
Offset field can be used to adjust the timecode
values if TL MasterMeter is being used for histor-
ical metering but the session was started from a
point other than the beginning. If TL MasterMe-
ter is being used in real time, the timecode infor-
mation in this column can be ignored.
At the bottom of the browser, the Peak field dis-
plays the highest dB value of the oversampled
audio received so far. The Events field shows the
historical total of clip events in the oversampled
audio signal. Once TL MasterMeter reaches 2000
clip events, it ceases to record additional events.
Although the meters remain active and the Peak
field continues to be updated, new events will
not be added to the browsers. The Events field
flashes ‘2000’ to indicate this condition.
The Oversampling field displays the current
oversampling factor in use by the DSP process-
ing. This will vary between 2x, 4x and 8x over-
sampling depending on the session sample rate.
The information in this browser is cleared using
the Clear button, or is cleared automatically
whenever the Pro Tools transport is started.
Signal Level Meter
The Signal Level meter shows the instantaneous
signal level of the current audio signal. The clip
light at the top of the meter can be cleared by
clicking on it, or by using the Clear button.
Oversampled Level Meter
The Oversampled Level meter shows the instan-
taneous signal level of the current audio signal
after it has been oversampled. As the oversam-
pling process can create levels above 0 dB, this
meter shows an expanded scale from –6 dB to
0 dB and from 0 dB to +6 dB.
The clip light at the top of the meter can be
cleared by clicking on it, or using the Clear but-
ton.
Clear Button
The Clear button clears all of the historical in-
formation displayed in Signal Clip Events
browser and the Oversampled Clip Events
browser. It also click the clip lights at the top of
the Signal Level and Oversampled Level meters.
This information is also cleared when the
Pro Tools transport is activated by pressing Play
or Record.
