Early
The Early group controls the character of the
early portion of the IR and the early reflections.
The primary control is Early Length which de-
fines the size of the early portion of the IR wave-
form. When loading an IR from an audio file,
TL Space relies on the user to define which part
of the IR is the early portion of the waveform. By
default, the Early length is set to 20 ms.
The early portion of the IR waveform is high-
lighted in the Waveform display. If Early length
is set to zero, then the Early setting have no ef-
fect on the audio. Otherwise, when changes are
made to any control in the Early group, the IR
waveform is recalculated and displayed in the
Waveform display.
Length
Adjusts the length of the Early reflec-
tions from zero to 500 ms. When set to zero,
other controls in the Early group have no effect
on the audio. The Early Length control adjusts
the point in the impulse where the early portion
ends and the late portion or tail begins.
For the most realistic reverb results, Early
Length should be adjusted while viewing the
waveform display. The early portion of a reverb
IR is typically seen as a series of discrete spikes at
the beginning of the waveform. Early Length
can however be adjusted to any value to explore
other creative possibilities.
Size
Changes the size of the Early reflections,
from 50% to 200%. Early Size expands or con-
tracts the reflections in the early portion of the
IR (as specified by the Early Length control). Re-
duce the Early Size to give the space a smaller,
tighter sound. Increase the Early Size to give the
space a larger, roomier sound.
Lo Cut
Early Lo Cut controls the frequency of a
highpass filter applied to the early portion of the
IR (as specified by the Early Length control). The
default setting of zero disables the highpass fil-
ter. As the control is set to a higher value, the
corner frequency of the highpass filter is in-
creased. Use this control to reduce boom and
low frequency cancellations that can happen
when mixing the reverb output with a dry sig-
nal.
Balance Early Balance controls the left/right
gain balance of the early portion of the IR (as
specified by the Early Length control). Adjust
the Balance to control the apparent position of
the reverb input in the stereo image. A negative
value reduces the right channel gain. A positive
value reduces the left channel gain.
When loading an IR from an audio file, TL
Space relies on the user to define which part
of the IR is the early portion of the wave-
form. If the Early Length is set to zero, con-
trols in the Early group will not affect the
IR.
