TL Space DSP Usage
TDM Systems
On Pro Tools HD and HD Accel systems,
TL Space can be instantiated as TL Space Short,
Medium and Long. The plug-in name displayed
in the menu refers to the maximum reverb time
as shown in the table below.
The different versions of TL Space have differ-
ent DSP usage requirements. A Pro Tools HD
card contains nine identical DSP chips. A Pro
Tools HD Accel card contains nine DSP chips,
four of which offer external SRAM. In some
modes, TL Space requires Accel chips with ex-
ternal SRAM. The following table shows the TL
Space DSP requirements by reverb time.
The number of DSP chips required is a function
of the number of inputs and outputs, and the
type of processing in use. The maximum chip
usage is 8 DSP chips across two HD Accel cards.
The following table shows the TL Space DSP re-
quirements by channel.
These numbers represent the maximum possible
DSP usage of TL Space Long. For example, TL
Space Medium has only 50% of the DSP require-
ment in supported stereo and quad channel for-
mats.
CPU Usage
On all Pro Tools systems, TL Space can be in-
stantiated as an RTAS plug-in. This impacts the
performance of the CPU. CPU usage can be mon-
itored in the System Usage window.
