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.

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?”

IT-based Broadcast Infrastructure and Audio Trends

Posted by Mike Daskalopoulos on October 15, 2014

Mike Daskalopoulos

In the last several years, the broadcast industry has begun making the rapid transition to IT-based infrastructure both for new facilities as well as upgrades of old facilities. Standards such as SMPTE 2022 have facilitated the transition from specialized rack-mounted appliances to commodity hardware that is increasingly cloud-enabled for scalability and redundancy. Encoding, decoding, packaging, switching and more are all virtualized to the point where even connectivity now is becoming largely virtualized for both traditional linear broadcast and second screen.

The Nuts and Bolts of Ethernet Switches: 4 Fast Tips to Make AoIP Easier

Posted by Marty Sacks on August 27, 2014

Nuts & BoltsSince Axia invented AoIP in 2003, I’ve had tons of conversations about Ethernet switches — as you might imagine! Switches are the heart of any AoIP system, so it makes sense to know a bit about them. But a lot of the language concerning Ethernet switches is fairly impenetrable (even to experienced engineers). So I thought that a post encapsulating some things I’ve learned might be useful to those of you planning your next facility.
