Here we look at the science of using a matched pair of microphones positioned as a coincident pair to capture stereo sound images.
The audio vectorscope is an excellent tool for assuring quality in stereo sound production, because it makes the virtual sound image visible in the same way that a television vectorscope allows the color signals to be seen.
Once the basic requirements for reproducing sound were in place, the most significant next step was to reproduce to some extent the spatial attributes of sound. Stereophony, using two channels, was the first successful system.
As users working from home are no longer limited to their working environment by the concept of a physical location, and infrastructures are moving more and more to the cloud-hybrid approach, the outdated concept of perimeter security is moving aside for zero-trust security.
Having looked at how microphones are supposed to work, here we see that what happens in practice isn’t quite the same because the ideal and the actual are somewhat different.
EBU R143 formalizes security practices for both broadcasters and vendors. This comprehensive list should be at the forefront of every broadcaster’s and vendor’s thoughts when designing and implementing IP media facilities.
As IT and broadcast infrastructures become ever more complex, the need to securely exchange data is becoming more challenging. NATS messaging is designed to simplify collaboration between often diverse software applications.
NMOS has succeeded in providing interoperability between media devices on IP infrastructures, and there are provisions within the specifications to help maintain system security.
