Internet Service Providers (ISPs) are experiencing significant growth in bandwidth consumption largely due to the uptake of OTT video services and the growth in numbers of connected devices per household. ISPs are therefore navigating the path of making investments in their networks that support their own financial requirements and their customers’ expectations.
Demand for internet connectivity continues to grow rapidly. Internet Exchange Providers are now part of our critical infrastructure and their integration with ISPs and Content Providers is defining CDN and network expansion.
With the ongoing growth of OTT content consumption, and the drive from live sports broadcasters to provide high-scale and high-quality Direct to Consumer OTT services, Streamers and their customers now demand streaming services that operate at the scale and quality of existing broadcast services.
Here we look from the state of the art in microphones, to what the future may bring with the enticing theoretical potential of microphone arrays built using MEMS technology.
M-S techniques provide useful sound-field positioning and a convenient way to check mono compatibility. We explain the hard science behind this often misunderstood technique.
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.
