Calrec IP Primer Part 4: Bandwidth
Bandwidth is a simple concept – it’s really just about how much data can be produced or consumed by a device on your IP network. The good news is that audio bandwidth is much less demanding than video, but that doesn’t mean that you don’t need to pay it the proper attention.
Lots of things affect bandwidth. Packet time has a huge influence on bandwidth, as does channel counts, sample rates and the choice of codec.
In this chapter of Calrec’s IP Primer, we learn how every network decision we make affects bandwidth, and we discover how each of those decisions can lead to over-subscription. In order to design scalable and reliable IP networks, the correct distribution of bandwidth is essential, and we spend a little time looking at that.
We’ll look at bandwidth again in a more practical way when we discuss Network Design in a few weeks, but this chapter introduces a number of concepts and includes a set of example bandwidths for various audio formats in a detailed Appendix. These numbers consider inter-packet gaps which make these examples more accurate references.
