The encoder can encode multiple instances of live audio for devices with varying bandwidth
requirements (e.g. HD-TVs, PCs, and smartphones). The lower area of the Audio page has a
set of parameters that can be controlled by preconfigured templates. Use the
button to populate the Audio Template Settings with preconfigured audio values. The audio
templates vary depending on the selected

Any stereo source containing different audio material will be mixed
down to mono. The net result is that the stereo effect is lost but the
encoding efficiency is doubled thereby reducing network
bandwidth while retaining sound quality.
AAC-HE is a highly-efficient audio compression technology that
uses spectral bandwidth replication (SBR). AAC-HE is optimized
for better quality at lower bit rates.
