7.1.3.4 Latency Minimization
About
In live applications the latency time of the reproduction system is always a critical issue. Below is a list that states sources of delay
introduced by an IOSONO system, parameters that can be used to lower the system latency (latency minimization) and drawbacks
that are introduced when setting parameters to allow for lowest system latency.
Sources of latency Measures Drawbacks
Segmentation of loudspeaker fi les. It
intro- duces loudspeaker groups with
fewer speakers in groups where possible.
Use of IOSONO algorithm only possible
in groups with suf
fi cient number of
loudspeakers.
Setup design
Keep reference point far away from
loudspeaker groups. Loudspeaker setups may not re fl ect the
reality.
Keep Buffer Size low (64/128 samples)
to minimize processing delay. Reduce
process- ing load to allow for small Buffer
Size by: Preset might not run properly, Underruns
in complex setups.
Keeping the number of Live Inputs to
required minimum. Less live inputs possible.
Use VBAP algorithm instead of IOSONO. Correct localization only at reference
point. Audio im- age limited to
loudspeaker array.
In render slots with IOSONO algorithm
applied select "Static Scene Rendering"
instead of "Optimized Moving Sources". Audible artifacts when moving sources.
