Imagine having a delay of exactly one second so it sounds like it's fine

imagine if they were evil and intentionally added a delay

The ball bounced 3 times befor I heard anything. Think there may be a slight delay.

Such a specific yet extremely useful thing. I'm glad there are people that come up with these videos for the off-chance they're needed.

I don't have any sync issues, I'm just really high.

My bluetooth headphones according to this are synced with the video but i still feel like there's a delay whenever i watch a video or even play a game.

Still one of the most useful videos I know on the entire internet

If you're struggling to discern I recommend clicking your fingers or clapping at the bounce point for the white ball as you anticipate it, and listening to the difference between the snap and the tock.

Works great. But I want a longer loop, so I can dance to it more.

This video is so beautifully simple, yet so incredibly useful. Thank you.

Used this at an event with an LED wall and Line Array. Perfectly synced the audio with video. Thank you for this

Imagine your heard the sound first before the ball hit to the ground... The ball: I Am Four Parallel Universes Ahead Of You

Tip for using this: Scroll down a bit until the bouncing ball is no longer visible but the white moving bars still are, then listen and try to sense which yellow bar seems to be "causing" the audio tick when it's crossed by a white bar. This will give you the audio delay down to the tenth of a second (1 tenth of a second = 100ms).

This is your daily dose of Recommendation Test of audio delay

This video allowed me to appreciate a difference in response and ghosting in a triple monitor system. Thanks to the creator

For some reason I have extreme paranoia that my computer audio will unsync or is unsynced even when its fine. I really appreciate this video because everytime I think that I can come back and prove that I'm just a dumbass.

As of Dec, 2015, sync is back - no more audio lag - awesome. Only took them 5 months to fix.

Sorry for the lack of Apple Juice! Please let us know how the audio/video sync is for you!

I don't know why i clicked this video but i do not regret it.

I've been using this video for almost a decade now for bluetooth audio devices on my and clients computers. Thank You!

Thanks for all the feedback! Seems like about 15% have the late audio problem, mostly with Firefox. No sync issues on Vimeo using any browser/platform, so it's definitely a KZfaq issue.

Well, everything was in sync for me. I also fully support fruitbaskets.

Thank you, I thought I was going crazy there for a moment.

make a 10 hour version or i cry

You guys never fail to amaze with the effort you put in to your kick ass videos. It's perfectly in sync on my LG Optimus F6

This is incredibly useful, I was testing a feature on my headphones and I heard it can increase audio latency so but I thought that doesn't matter so I tested if it's even noticeable and it feels like there is no difference.

Thanks! I thought my headphones were out of Sync but it turns out it was just whoever made the video.

Really nicely done, could just be a little batter if it were 60fps too

Most helpful video on KZfaq?

after watching this I've become sound incarnate

Currently using bluetooth headphones and thought there was a delay. This is so useful.

note: depending on if you're using bluetooth audio, this video may not work for calculating delay due to youtube automatically compensation for bluetooth audio delay (if there is any delay between pressing play/pause when listening to a song)

The sync was fine for me in Chrome. Now i wait for more Styrofoam Nuns.

I think i have a super power of making anything funny for myself. I just watched this video and started laughing hysterically when i thought about it.

*THE BOUNCING SOUND IS KINDA ASMR THO.* 😴

as a pong player from way back, I find this mesmerizing. Have to stop watching now.

Audio sync is working here! Chromium, Linux, Ubuntu 15.04.

Perfect. I was testing my new video projector. It have a wireless feature using Miracast. Thanks to this video now I know it have a delay of almost 200ms using Miracast, making it pretty annoying to play movies and videos on it, but this delay doesn't happen with the HDMI cable.

Thumbs up! Just a test. Just a video. No 10 min blablablabla. Perfect. Thx

i like the part where the ball bounced and made that sound.... that was cool....

This is perfect! I will be using this video non stop to test latency for my digital audio via spdif configs!

Finally headphones with minimal delay

years of this video being useful for me every time i have a doubt in the output sound

Set the speed of the video : (0.25) to be able to know more accurately

i dont understand. why my cheap chinese brand bluetooth headset was sync with this video. but my expensive as hell earbud was out of sync i still can't find the solution

Simple but super useful. Easy to calculate delay from the moving dash at the bottom.

Her: "So what kind of music are you into?" Me:

Pov: you bought a new bluetooth earphone

yeah yeah yeah now ive got a woody i have to sit back like this

the fact that most of the videos I watch have like 0.3 seconds delay, but this one doesn't is making me anxious

Even after 5 years...this works freaking fine😮

Men this fake Chinese AirPods are good

This is actually extremely useful. Try closing your eyes and pausing on the clicks, and then check the latency. I get around 200ms with my bluetooth earbuds still, damnit.

i needed to test my new JBL bluetooth headset and i got just a slight delay, not even a 10th of a second so im very happy, thanks for this video, simple but so handy, cheers from Sweden!!

Watch it at 0.25x playback speed

Audio is a little early for me, and gets worse after I use the seek bar. Starts off at about a 10th of a second, then gets up to about 2 10ths of a second. I'm on Chrome HTML5.

My Bluetooth head buds were 4 10ths of a second off

What a useful video, thanks for uploading

You're amazing man this helped me with what I thought was a speaker issue, ended up confirming it was a video sync issue. I would recommend if possible having different versions if possible, or maybe even 1... 1/2... 1.... 1/2.... 1... 1/2... this way we can confirm it's not just a 1-sec delay. But that's just me being nitpicky, thanks for the vid!!! It's really appreciated.

That's worth taking out my hand for.

That's odd. I tested wireless and wired. I know that my wireless connection has a big delay, this is very obvious in-game. For some reason, it seems to be spot-on in this test. I know there isn't any software interference except maybe for Chrome because the sound goes through a physical mixer, the Elgato Wave:3.

I can just watch this all day.

I just got the new airpod pros and theres NO DELAY.... ITS AMAZING. I love these things.

If you close your eyes and open it only when you hear the sound you see the perfect audio delay of your bluethoot earphones, or 0 delay (in my case) of cable earphones. Thanks @dayjoborchestra this video is useful!

Feliz de que mis audífonos inalambricos están a toda madre jajaj

Best 1 minute and three seconds of my life

Thank you for this. I was worried my recicer had a delay but this shows it's fine. Pretty relaxing to watch too.

Yeah fuck trap i'm into this now, i'm really feeling it

Thanks for this video!

I used this to check and test my brand new wireless bluetooth in-ears. Never had any of those before. 🤣

Out of the 1.6M views, I think i contributed to atleast 120,000 of them.

I have less than 1/10 of a second of delay. Just enough to make everything off, but not enough where it's a big issue. Still really irritating though.

I got fastest one sound comes first.

It has been a while til I realize that I use my cabled headphone instead bluetooth one and I was facinated.

Just got the Apple Airpods max. No latency lag. Everything is perfect.

Worked fine with Waterfox 64bit 1080p

That moment when you have 10ths of a second of delay

I have to come back to this video all the time to make sure it is in fact not my headphones that are fucked and indeed whatever video i was watching before

This video will be get more and more views because this the only video that really known for latency testing

I'm here because I'm having sync issues again

The sound comes in before the video near the end.. using Chrome on Windows 7... off by maybe 1/10ths of a second at about 50sec.

Thanks! Got my first wireless headphones today and this video was perfect for it, virtually no delay.

Idk why I just stood there for the entire video

Audio is about 3 10ths of a second late from our end.

My screen or my cellphone speaker is delayed like 0.2 sec i think

Perfectly synced with AirPods Pro 2nd Gen

Okay, i had some ms delay before so I reset my device and now it's working perfectly. Thanks to this audio check video.

AirPods latest model doing good with the no latency

"I'm experiencing delay on games, but not on KZfaq, Netflix or other video players. Why is this happening?" A: Every bluetooth device have audio delay, But you don't notice it on KZfaq because almost every video program compensate it by delaying the video output. This can't be done in game because you need to have instant video response.

This is extremely useful! I use it to confirm my sound system is synced with the computer. Thank you :)

I came here like 50 times and this is the first time I’m happy

Mine is more than a second

This video itself is delayed. Put it at .5 speed and you will see it is early

I tested it on my car's bluetooth, it is exactly one second. It is done by design to discourage you from watching KZfaq while driving.

In the depression, the bouncing ball seems happier than me

Fire some apples at the IRS building

How many pandas were harmed in the making of this videogramme?

Dude it literally feels like 0ms latency. On point. 😳

This is the best video to check out his good Samsung smart view works.

I can see no sync issues in Chrome or Firefox at all. However, I've been using the HTML5 player on KZfaq for ages and have never had any problems. MP4, 720p video. Edit: No issues in IE 11 on a Windows 8.1 laptop. The Chromium browser and latest Firefox also show no problems on the same laptop. Edit 2: No sync issues on a Samsung 550C Chromebook either. Note that this particular machine has only a Celeron 1.3 Ghz processor with 4 GB of RAM. Yes, it doesn't have the overhead of Windows and such, it just runs Chrome OS, but still, audio is perfectly fine. I'm thinking it must be something on your end. I get that you see the issue on multiple PCs and browsers, but I can't reproduce it on any of my boxes.
