It seems almost superfluous today to specify that audio is digital because most audio capture, production and distribution today is done numerically. This was not always the case and at one time audio was primarily done without the help of numbers and the term digital audio was introduced to distinguish the new technology from what went before.
There is level and then there is loudness. Neither can be measured absolutely, but by adopting standardized approaches it is possible to have measurements that are useful.
There are two basic reasons to know the level of an audio signal. One of these is more technical and one of them is more subjective.
OTT delivery continues to expand to meet the relentless growing consumer demand. This trend shows no chance of abating and technologists are continually looking to innovation to scale infrastructures accordingly. In this sponsors perspective, Ryan Nicometo, SVP of Product for Vecima, presents the OTT Scale – Maturity Quadrant to help decision makers clearly see the potential technical challenges and opportunities to meet the demands of OTT delivery.
Whether we’re routing signals or remotely operating equipment, the need for reliable system control is one of the most important aspects of a broadcast facility. But as we migrate to IP, some of the working practices we took for granted with SDI operation don’t necessarily transfer and this is most evident in signal routing.
For many years broadcasters have been working with static systems that are difficult to change and upgrade. Although we have video and audio routing, the often-tangled mess of jackfield patch-cords is testament to how flexible broadcast systems really need to be to meet the demands of modern program making.
SDI is one of those technologies that is so well established and ubiquitous it can almost be taken for granted.
These days TV broadcasters are working feverishly to work out new remote production workflows for stay-at-home talent, but for radio broadcasters it’s been business as usual. In fact, many engineers have found that the remote control features they already use for troubleshooting are highly extensible and can be slightly modified for use by production staff.
