364 GLOSSARY
The right handle adjusts the fade out time, the time when fade begins to lower the object's
volume.
Volume handle: The middle handle adjusts object volume. This works independently from
the track volume fader or volume automation curves. You can also access object volume in
the object editor. The level is displayed in a tooltip.
Hybrid Engine and Economy Tracks
Very small audio buffers ("Low Latency" mode) increase the CPU strain of the playback
engine. For the optimum use of the PC resources we recommend using the mixer tracks
(which really require this low latency) in "Low Latency" mode only. This includes:
• Monitor tracks
• Tracks with VSTis
Tracks that play hard disk content (MIDI or audio files) can be taken out of "Low Latency"
mode in the Hybrid Engine by assigning the "Economy" property to them. These tracks
then use the buffer size of the play engine (VIP buffer size).
Latency
Audio latency and response latency are of interest when working with audio applications.
Audio latency is the delay of audio data when being processed through an audio function
unit (effect plug-ins, DAW audio engines, digital mixers, hardware effect devices, DA/DA
converters, etc.). The entire audio latency is made up of the sum of the latency of the
sound card (ASIO latency) and the latency of the effects used in monitoring tracks and the
master. When monitoring, these latencies are disruptive even at 5 ms.
Response latency is the delay between the use of a sound producing or sound modifying
control element and the audible change or generation of the sound. The response latency
is made up of the sum or the output latency of the sound card, the latency of used effects,
the latency of the play engine, and possibly the latency of the MIDI input/graphical user
interface latency of the PC operating system.
When using MIDI controlled synthesizers (VSTi's) the response latency is similarly critical,
much like audio latency, in monitoring (disruptive after 5 ms).
When playing files with the play engine, response latencies created by effects and the play
engine itself are much less problematic (disruptive after ca. 250 ms).
The internal effects show the latency which causes the effect in the lower control element
list of the effects. The latency of the sound card in conjunction with the driver being used is
displayed in "System/Global audio options" ("Y" key). The entire latency of all effects is
shown in the status bar once playback begins.
Latency comparison
When using effects which cause latency, you must make sure that there is no time delay
with parallel tracks, objects, or AUX channels. Depending on the location where effects
