Audio Analysis and Monitoring
The technical and subjective monitoring of audio is typically more involved than video. Audio workflows involve the production of many different packaged deliverables with many tens or hundreds of mic sources, dozens of stems, multiple mixes say for host and world feeds, multiple languages. An international sports host broadcaster servicing several unilaterals in addition to the world feed may have to deliver 10’s of video feeds, but several thousand channels of accompanying audio.
There are a huge range of audio formats with everything from mono, dual mono, 2.0 stereo, all the different combinations of multichannel and now immersive channel and object-based formats.
Adding a new live format to an existing service requires an understanding of operator working practices, training, and skill sets so that the new technology can be blended in without causing major disruptions. There needs to be a clear understanding throughout the organization of the added value that this format will bring. Simplifying the live-mix control and monitoring of multiple formats is key to enabling the smooth transition.
In terms of carriage of audio over IP we have both AES67 and now SMPTE ST 2110-30 and -31, with a requirement for up to 64 channels of audio (ST 2110-30 Class C).
Each PHABRIX instrument offers an exceptional audio analysis and monitoring toolset to help diagnose problems.
