The difference between using a wired and wireless microphone for a specific job is no longer about sound quality. It’s about a group of other factors, many of which users should consider before making the choice.
Virtually every editing or audio mixing set-up uses audio monitor speakers — most often sitting on the either side of a computer monitor on the desktop. In these scenarios, the physical transfer of vibrations from the speakers to the desk’s hard surface can create a boost of mid and low frequencies. This is called vibration-loading.
In Part 3 of this series on speaker technology, we saw that accurate loudspeakers need to consider the time, space and frequency domains. Now it is useful to consider what that means in terms of arriving at some kind of specification for a real loudspeaker.
Dolby Laboratories said that its Atmos immersive audio technology is now installed in 2,000 suitably equipped cinema screens and that more than 500 titles have been mixed in Dolby Atmos. In addition, Dolby Atmos multi-channel mixing technology is now deployed in more than 60 countries and more than 150 post-production facilities.
For most people working in pro audio, phantom power is fed through a mic cable from a mixer to bring electricity to condenser microphones. That’s what they know — period. However, working pros in the audio field know there is much, much more to this “phantom” power flow. It pays to know the subject to avoid the “gotchas.”
Killing unwanted noises when using a microphone requires the knowledge and skill to know the type of noise and have the available tools to suppress it. Here’s a guide to the basics of removing noise when using microphones for recording.
In Part 2, of John Watkinson’s series of articles on loudspeakers, the critical time-domain operation of human hearing was considered. In Part 3, he explains how the frequency domain interacts with the time domain and why they are a crucial concern in any accurate loudspeaker design.
In the last article, we looked at Quality of Service in IT networks. In this article, we continue the theme of looking at a network from a broadcast engineers’ point of view so they can better communicate with the IT department, and look at the benefits of sending audio over IP.
