Computer latency: 1977-2017:

Almost every computer and mobile device that people buy today is slower than common models of computers from the 70s and 80s. Low-latency gaming desktops and the ipad pro can get into the same range as quick machines from thirty to forty years ago, but most off-the-shelf devices aren’t even close.

Reminds me of this: Microsoft vscode: CPU usage even when idle (due to cursor rendering):

VS Code uses 13% CPU when focused and idle, draining battery. This is likely due to the blinking cursor rendering. I think CPU usage when focused-and-idle could ideally be near-0%.

I've been thinking about this problem a bit in audio. Wireless mic setups are pricey, and of course everyone wants to know if they can use Bluetooth. That, of course, adds a 50ms latency, which is too much for live performance.

But as I've been looking at other applications, so much adds latency that can't work live, things that'd be easy with a DSP end up really wanting analog solutions...

We will not edit your comments. However, we may delete your comments, or cause them to be hidden behind another link, if we feel they detract from the conversation. Commercial plugs are fine, if they are relevant to the conversation, and if you don't try to pretend to be a consumer. Annoying endorsements will be deleted if you're lucky, if you're not a whole bunch of people smarter and more articulate than you will ridicule you, and we will leave such ridicule in place.
