As the Twentieth Century is rapidly receding in the rear-view mirror, historians, archivists and collectors furiously gather artifacts and documents before they all disappear. Forgotten by many, but not all, are the soundscapes of the past; both technological and natural in origin.

If you've worked in radio long enough, you already know something about changing soundscapes. The clattering of a [teletype machine](https://www.youtube.com/watch?v=FWa6u5_Itvs) in the newsroom, the sound of records and reel tapes being cued and the once per second chunk-chunk-chunk of the Western Union master clock as it counts down the time remaining till the next hourly newscast, are all gone but not forgotten.

# TWiRT 338 - The Standard that Stuck - with Richard Burden 

Cassette tapes. 8-Track. Digital Cassettes. FM-QUAD. AM Stereo. Reel-to-reel.  Audio standards come and go, but Multiplex FM Stereo lives on and is nearly 60 years old! Richard Burden extensively tested our FM Stereo system when it was just a proposal. Dick joins me to chat about that and more on TWiRT!

# 5 Advantages of Switching to a Broadcast VoIP Phone System

We live in an increasingly digital and largely networked world. It’s no accident that AoIP is taking radio and TV by storm: the economies of scale, ease of use, and return on investment are undeniable. Traditional POTS and ISDN phone services are steadily being supplanted by SIP- and VoIP-based methods at the service-provider level. ISDN is already unavailable for many new installations, and POTS is moving that way now. A SIP/VoIP phone system offers digital phone services that cost less, sound better, and are more easily managed than traditional services.

The arrangement of equipment in radio studio control rooms was often the result of a tussle between programmers and engineers. In one extreme, the control room may have been a dream for jocks to operate, but a nightmare for techs to service. Too far the other way, and you had a setup that could be easily serviced, but required an octopus to operate. Most were a compromise (although some would be better termed a stalemate).

# TWiRT 337 - Predicting Headphone Sound Quality with Sean Olive

How many times have you bought headphones or earbuds, only to be disappointed with their audio quality? Or maybe you were pleasantly surprised! Sean Olive is the Acoustic Research Fellow at HARMAN International. He’s doing headphone qualitative measurements that mean something, both for consumers and for manufacturers, toward better audio from our wearables.

# Radio Magazine: Frank Foti on Audio Processing for Broadcast Streaming

When it comes to broadcast streaming, there is a big difference between audio processing for streaming and audio processing for over-the-air. In the February 2017 issue of *Radio* magazine, Doug Irwin interviewed Frank Foti, along with other audio-processing experts, on how to process audio for broadcast streaming properly, asking them about the design differences between over-the-air processors and those designed for streaming media.

# TWiRT 336 - Hands-On AES67 with Patrick Killianey

Perhaps you’ve heard of AES67 for IP-Audio. It allows cross-connection of different, competing AoIP standards like Ravenna, Dante, and Livewire+. But until you actually try connecting audio devices together, AES67 is just a standard on paper. IP-Audio expert, Patrick Killianey from Yamaha Pro Audio is here to explain real-world AES67 from our recent technology demo

# ![Emergency Alert System](https://blogs.telosalliance.com/hs-fs/hubfs/Direct_Current/EAS.jpg?width=340&name=EAS.jpg "Emergency Alert System")Untangling EAS with Pathfinder

For many years, broadcast stations have been required by law to incorporate emergency alerting into their air chains—usually directly in line with the program path as the last stage prior to the transmitter. As station groups have consolidated and air chains have become more complex, however, managing this insertion gets a bit trickier. What used to be a 1:1 correspondence between studios, transmitters, and everything in between is often now a matrix of possibilities including multiple studios or automation outputs, along with main and backup program paths and transmitters.
