Podcasting was booming, but the gear to do it with was sputtering. Podcasters had to choose between equipment that was overly engineered and expensive, or so inexpensive and simple that quality was sacri ced. But Bryan had a solution: a broadcast-quality dynamic microphone with a built-in USB interface. It had to sound great right out of the box, with ease of use for both novice and pro.

  • Ip-12 · Ip-16 Advanced Modular Networkable Consoles
    IP-12 · IP-16 ADVANCED MODULAR NETWORKABLE CONSOLES Flexible. Affordable. Built To Last. Audioarts consoles and control surfaces Between 2000 and 2013 Audioarts has sold over 10,000 consoles. Virtually every one of them is still in service. As are the many thousands sold before 2000. Audioarts carved a niche for itself, pushing the radio console into the modern age. Today, we’re considered the standard in analog and digital audio consoles for radio. Our IP-12 and IP-16 extend Audioarts’ reach into the world of the WheatNet-IP Intelligent Network. With its modular design, it is quickly adaptable to be an on-air or production board, customized to any configuration you need. WheatNet-IP compatibility extends its reach outside the studio and opens it to unlimited sources from virtually anywhere. WheatNet-IP: The Intelligent Network We looked at the world of AoIP Networking and thought long and hard before jumping in. The stuff that was out there was OK, but left a LOT of room for improvement. For starters, the way the workload was distributed had to change. Rather than having a single point call the shots, we thought it important to have distributed intelligence built into WheatNet-IP. What this means is that every BLADE (or node) has the DNA of the entire network and can operate in any position on the network. It means that the network can configure itself, as every BLADE is self-aware. It means the network can heal itself - if a BLADE fails (fat chance) just put a new one in its place and watch it set itself up.

  • Introduction to Broadcast Media
    Introduction to Broadcast Media Tutorial Cutting to the chase: Broadcast media is radio and television. Even amidst the pop culture dominance of the internet, broadcast media still commands the largest share of the advertising pie nationwide. Put the audio and visual media to work for you as your company earns larger market share, stronger branding, and increased sales. If you are looking for cost-efficient lead generation, you need to be looking at radio and television advertising. Not only are radio and television the main media for advertising today, they are continually developing new ways to reach their audience. The SyFy cable network launched a show (“Defiance”) that combines interactions on a video game with the plot of a series show. Radio stations are supplementing on-air campaigns with digital media to provide on-air and on-screen promotions to those who stream the station through their computer. Multiple studies have shown that combining radio and television can help advertisers reach audiences not achievable with only one medium or the other. Broadcast Media Broadcast television Cable television On-demand television TV/web integration Local, network, and national radio On-air endorsements Long-form programming Multi-language programming The Power of Radio Radio reaches more Americans than any other advertising media. As an example, let’s look at Los Angeles, CA. It is the #1 radio revenue market in the world and generates more than $1 billion dollars in sales each year. In that market alone, more than 9 million people listen to radio each week. People are loyal to radio and love listening to their favorite DJ or talk show host.
