Sample Rates and Interoperability

Sample Rates and Interoperability

What would you say if someone tried to sell you a new car that didn’t run on gas or battery? Exactly. We thought the same thing, which is why we designed our AoIP with selectable sample rates. The WheatNet-IP Intelligent Network has selectable audio sample rates of 44.1kHz or 48kHz, which is critical to music creation, storage and replay now as well as under any proposed interoperability standard going forward.

 

Sure, it would have been easier to insist broadcasters go with one sample rate.

But, locking broadcasters into sampling at 48kHz, for example, would mean that every bit of audio originated on a CD would have to be sample-rate converted in order to pass through the system. As it is, 44.1kHz is the Red Book audio CD base sample rate, and therefore the sample rate already used for most radio music libraries. An AoIP system that requires the majority of radio broadcasters to convert their entire CD libraries to 48kHz sampling just seems cruel and an unnecessary loss of audio quality.

Besides, sample rate flexibility is in the true spirit of studio interoperability.

Wheatstone is a proponent of studio interoperability as well as an active member of organizations such as the AES X192 task force.
