Caracol TV uses advanced digital television equipment and technologies at its facility in Bogota. When the network set out to update its equipment to HD, Caracol TV decided that it needed a means of measuring and monitoring loudness, as well as accuracy of measurement.

"We selected LAMBDA because it is the most complete and accurate digital audio meter for loudness," explains Juan Pablo CaÒizares Arango, audio engineer for Caracol TV. "The readings from the LAMBDA display make it easy for me to know how to adjust the dialnorm so that our Dolby Digital [AC-3] signals sound the best that they can. Audio is often overlooked when it comes to broadcast solutions. I think it is very important that a company like Linear Acoustic is so focused on audio for broadcast."

The LAMBDA displays both audio and metadata, and allows simulation of metadata effects to provide accurate monitoring. Front-panel controls allow quick stepping through any channel, channel pair or downmix. The display features metering of eight audio channels plus numeric loudness and metadata indication. In addition to a numerical readout, a thin line indicating measured loudness "floats" over audio metering allowing verification of program loudness.

Though currently only broadcasting in stereo, Caracol TV has plans to switch over to multichannel in the next few years. To help with the switch and the loudness issues associated with surround broadcasts, the station has plans to add a Linear Acoustic AERO.air 5.1 10-channel loudness manager for further control to its audio workflow.
