How much audio latency can you detect?

- This video will test your ability to detect audio latency, that is the delay between what you see in the display and what you hear from the speaker.
Ready for the challenge?
This idea came as a result of my project making a meter to measure the audio latency, especially on Bluetooth devices which they currently suffer from a considerable amount of delay (over 100 ms).

Videos like this are gems! It's one of those things where people don't usually look for or need it, until they NEED IT! Then the full appreciation and value of it is presented. I wanted to make sure I communciated my appreciation (2 years after it was made) Thank you sir!
That's so nice of you. Thank you. It's for people like you that make the effort worthwhile
Interesting that human ability to detect latancy between visual and audio is quite poor compared to our ability to detect latancy between tactile and audio.
Most musicians can tell the diference between 10ms and 5ms when playing an instrument with delayed audio such as electronic drums.
Thanks for this hard work ❤
You're welcome 😊
Can you make it for like 5, 10, 15, 20 millisecond delay? 67 was too easy for me even at double speed.
Really? Wow, in a way that makes you the winner of this game, because I only intended for typical people. Below 50ms territory we are getting into the margin of error of your audio system so that's why 67ms was the minimum. Also, like I said, the purpose was to test typical people.
The only way I can detect below 50 is playing a musical instrument, but that's another subject.
Thanks for sharing, buddy
It’s very fun to do and test the head[hone. Thank you for the video.
I'm glad :)
thank you very much for this useful video because i really needed it and once again i realized that airpods pro 2 is a great headset😊
thanks for the video. the delay between light and sound seems suspiciously low. practically unrecognizable at 100ms but if it's authentic then i shouldnt worry about getting wireless IEM with 80ms delay.
I guess also depends on the situation. For example I can noticed latency above 30ms in digital instruments, but watching a movie I can't notice 100ms
I got better through the video, meaning that I was detecting the delays and then having to try and error a couple of times before learned how many time each delay was. 600-500-300ms I started to get right from mid to end. 200-100 I got more right than wrong, but not 100% of the time. 67-0 for me is like a coin toss.
My result it's similar. 67ms is not really notable. 100ms I can always notice, though. The more practice, the better we get. But the funny part is that some people I've seen they can't notice 400ms.
Thank you for your feedback
@@interlinkknightI agree, 67ms is extremely hard to notice, but 100ms is just enough to be noticeable.
I'm pretty good at this. I was looking for a video that would play audio that was various ms out of sync over drums so I could see how easily I could hear it.
If you are curious I dont notice 100ms or less sound delay. But I notice any time the sound plays first.
Thank you for sharing.
That means you can detect 64ms if the sound is first? That's interesting.
For me, I sometimes noticed 100ms with either sound or light first, but I could not pickup 64ms no matter what was first.
I liked the test, my headset is very good.
Subscribed! My Bluetooth speaker has almost no delay.
That's awesome. Thanks for sharing
all i feel like is my pc sound is delayed by like 67 ms's because when it did the no delay, seemed to me like light when first, and when sound when first by 67 it felt like zero delay.
Oh, that's a good point. I made a device that can measure the delay between the display and the sound system, but you would have to be able to build it. Anyway, I would test with another audio system or a different way to connect it to the computer
100 milliseconds on headphones (wire) and speakers Logitech Z5500 S/PDIF, no problem.
Thanks for sharing your result
Actually, when you said sound and light were simultaneous w/o any latency, my eyes saw it first and then the sound coming from my speakers about 1 foot away detected the 0.000000001 delay. NOT! Great video.
Sadly, there are external variables like your sound system plus the player in your browser or app. I can't control those variables. All I can say is that I tested this video with my audio latency meter and it was quite accurate
@@interlinkknight I was joking.
Oh, I see now. My bad 😃
One foot is one millisecond so your joke's not that ridiculous. A musician will have real trouble playing in time with someone a few tens of meters away.
Call me psychopath but in all answers I was right before you showed the actual ms
Really? You can even detect the 67ms delay?
I would like to try this test with high frame rate video, 120fps +
At 30fps one frame lasts 33ms.
You mean you can detect 33ms?
Dude, 67 ms is really easy to tell. as well as 33. Things become more difficult under 20ms. This test is not for "typical" people as u said earlier in the comments, but just people with a bad audio system apparently
