When we’re chasing down audio gremlins like hum or jitter it’s always helpful to know what’s actually happening.
Take hum for example. We might suspect a nasty buzz is caused by something (seemingly) obvious, like the AC powerline, but later find out it was from a cable TV ground.
Or jitter. If we hear an improvement in sound quality after upgrading our ethernet cables we might think we’re lowering jitter. Of course, there is no timing in ethernet (so no jitter either), though it’s entirely possible we lowered noise and that affected something else that’s prone to jitter down the line.
If we know what “tree” our problem is sitting in it’s a heck of a lot more effective than simply barking up every tree until something shakes loose.
Take a moment to understand the potential sources of the problem first.
You’re much more likely to catch what’s hiding up in that problem tree.
