Colombian private broadcaster Caracol TV is monitoring and adjusting the loudness of its HD broadcasts with the installation of a Linear Acoustic LAMBDA professional digital audio and metadata monitor in its Bogotá facility.
When the network set out to update its equipment to HD, Caracol TV decided it needed an easy, effective way to provide accurate measurement and monitoring of loudness.
The LAMBDA displays both audio and metadata and allows simulation of metadata effects to provide accurate monitoring. Front-panel controls allow users to step through any channel, channel pair or downmix quickly. The display features metering of eight audio channels and numeric loudness and metadata indication. In addition to a numerical readout, a thin line indicating measured loudness "floats" over audio metering, allowing quick verification of program loudness.
