The first Axia console display, at NAB Las Vegas.Part 1: Nerves and Networking

At 11:59 P.M. on a Sunday in April, 2002, I was sitting on the thinly carpeted floor of the NAB convention hall watching as a software guru fed lines of code into his IBM Thinkpad. The next morning, the doors of the hall would open, and our newest product – a console surface IP-connected DSP mixing engine – would be displayed for the examination of broadcasters from all over the world.

Get the Sound YOU Want: A Programmer's Guide to Processing

Posted by Denny Sanders on October 14, 2015

Denny SandersBefore I joined The Telos Alliance fulltime in 2001, I was involved in the programming and management of some pretty successful American radio stations for almost 35 years.

Quite early on, I realized that the audio signature of a station is the final stop in the presentation process and is, in some ways, the most critical piece of the programming puzzle. This is not simply a question of aesthetics. Time and time again, TSL reduction can be traced to improper audio processing, where listener fatigue robs you of your most important listeners: The P1 long termers.

DC-Streaming_HistorySo what’s it all about?

By this point, most of us have heard the stories a million times…Streaming, streaming, streaming.

MT2000: The Audio Guru's Ultimate Multi-Tool

Posted by Dave Sarkies on February 11, 2015

Larry SchindelFor years, end-to-end system testing of digital audio in broadcast chains involved large, clunky, pieces of equipment. Bring multichannel and coded audio into the picture, and this became even more complicated. Devices such as the Dolby® DM100 made this a bit simpler, but are now obsolete.

The Linear Acoustic® MT2000™ Multichannel Bitstream Analyzer fills this void, meeting the need for an updated device capable of analyzing audio in multiple formats, carried via multiple interfaces.

Secrets of Streaming Audio

Posted by Dave Sarkies on January 28, 2015

Ioan RusFor several years now, streaming audio has been an increasingly popular, non-traditional format for audio content. While many broadcasters stream their stations online, many in the streaming audio world do not hail from a traditional broadcast background and aren’t affiliated with terrestrial radio.

And it may depend on the content. ProSTREAM designer Ioan Rus says his first question for streamers is always, “What are you trying to do?”
