disable all the audio devices in your computer, and run a DPC latency check to see that there are not any system processes causing latency spikes. You may have to disable some devices, network adapter is often the culprit. If you run DPC and are in the "green", have a good interface, then it comes down to processing power of your computer. You may need an upgrade. Good luck.

I just added the 202hd and 204hd to ny round trip latency chart

I was really surprised by the performance of that thing, especially for 60 bucks!

Be STRONGLY advised though, those are entirely different interfaces than the umc22. They have actual asio drivers....good asio drivers. A lot of the others don't have their own and instead use asio4all with much much worse performance, be sure to check when looking at their interfaces whether they actually have their own drivers

here's a handy reference to learn how to identify latency in milliseconds by ear training and listening

RTL UTILITY
RTL Utility is a tool for measuring the Round Trip Latency of your Digital Audio Workstation (DAW) and audio interface. The utility is used for low latency performance testing by system builders, reviewers, device manufacturers and at dawbench.com.

When your DAW sends data to your audio interface for playback, it doesn't send a continuous stream of data one bit at a time. What it does is fill up a section of RAM called a buffer and sends that in a single message when it is ready. Before sending the next message it has to fill the buffer again. This wait time introduces a latency, or delay, between something happening in your DAW and when you actually hear it.

While you are recording, the audio interface buffers and sends data to your DAW in a similar fashion. This introduces latency into your recordings.

If you send a signal from your DAW, out through the audio interface and back in via a loopback patch, then there will be a round trip latency which is the sum of the output and input delays. This is the RTL.
