Sound delay measurement

Hey guys, I’m now thinking about what I can do to measure the time it takes from the point where the computer receives the audio input (through the usual audio input on the sound card) to the point where there is something to work with, for example. noise reduction or something like that.
The main problem that I think is to measure when the audio signal was created and the timing of the sender and receiver.
So far I have come up with the following ideas:

• Use the serial port to transmit timing information • Put a timestamp in the audio signal
• Repeat signal transmission - a delay will be visible

Do you have more ideas or something that I don’t see in mine?
I thought I would find more academic work on this issue, but it was sad to see that this was not so, was I looking wrong?
Help is appreciated! Thanks in advance!

you can check the latency in the windows using this tool, they also have excellent information on the site, you can also read about ASIO drivers or try to contact the communities that use these tools (scriptwriters for DJ guitars), another is an excellent source information. Sources of projects, such as JACK, that have more technical information:
