Acoustic impedance is analogous to electrical impedance, and we all know that impedance matching is important in electronic systems. Here John Watkinson looks at the importance of acoustic impedance to loudspeaker design.
Changes in the broadcast industry are bringing far-reaching repercussions. In particular, studios, control rooms and production houses alike are all seeking ways to streamline processes, adapt workflows and work in a faster and more intuitive way. This has given rise to a number of trends across the industry. But should equipment designers and manufacturers be swayed by these when choosing display technology?
Nearly 50 years ago — 1969 to be exact — Sony introduced the ECM-50, a tiny peanut-sized electret condenser lavalier microphone that virtually ended the reign of large, cumbersome microphones used in television broadcasting. Since then, the scope, quality and price of lavalier microphones has dramatically expanded. Here’s a look at what’s available now.
From the earliest days of professional sound, a single microphone was used in broadcast studios and on stage to capture everything — from actors doing drama to music performers. Then, when the close-miking multitrack era arrived, the trend disappeared. Now single-mic sound is back and growing in popularity.
360-degree video is hot. Global 360-degree camera sales are expected to grow at an impressive CAGR of more than 35% through 2020. When will 360-degree news production begin? It’s happening now say some experts.
Having spent much time and energy exploring AES67 (see our recent 3-part series, “Your practical guide to AES67, Parts 1-3”), we’d now like to turn our attention to AES70 – what is it, how does it relate to AES67 and why do we need it?
Away from traditional broadcasting a revolution is happening. Live internet streaming is taking the world by storm with unprecedented viewing figures and improved accessibility for brands looking to reach better targeted audiences. The Live Explosion, hosted by the DPP in London and enabled by Dropbox, presented three live streaming experts to share their experience of this new phenomenon.
A quick look at the lens to display pipeline highlights some trivial-seeming bottlenecks that place important constraints on motion imaging systems. One of these is the connection to the consumer display. The announcement of HDMI 2.1 is key to advancing to 4K and beyond, with additional support for HDR, and increased frame rates for UHD video.
