Best way to manually adjust Audio Delay

[hammettjr]

Hi All, My setup is as simple as can be. I have a Samsung LN46A550 and I'm currently using the TV speaker. (I'm waiting until I move to enhance my setup.)

I've noticed a slight issue with lip sync (Blu Ray and HD programming). I found the Audio Delay setting in the Service Menu of my TV (which was set to 36) and tried adjusting it based on lip movement, but have found it very difficult to get accurate.

What can I use to help me adjust the Audio Delay correctly? Is there a disc I can use, or are there any other methods I may find easier?

Thanks for your help,
Matt

I doubt there is such a disc but since you found the delay settings that is your best bet. Try it down to 0 and then just try it at different setting, not 1 unit differences, too small to notice most likely. One of those hit and miss. And, perhaps not all programs have the sync issue?

Thanks for the advice. That's basically what I did, I just had a hard time reading lips properly. (It would be great if I could find a disc that simply output the sound and blinking light of a metronome!) I understand that the sync will differ based on program, channel etc. but I'm assuming that my blu-ray player will atleast be consistent across movies. I plan to 'fix' the problem for Blu Ray and hope most TV shows will be close.

Yes, the blu should be consistent with the sources. I would think you will need some listening and watching with setting to see if it looks and sound right. Also, you worrying over this will draw you attention to it even more. I would suggest if the high numbers are not working dial back 5 units at a time and see how that works for a while.

The Digital Video Essentials disc has "Time and Motion" tests that help determine if there is any audio - video sync issues.

You could use a DVD with behind the scenes footage that has a clapperboard visible as the directer shouts "action". Maybe even a concert video that has a good shot of the drums.

I'm not sure how accurate that will be, but it will be cheep!

Do what agarwalro suggests, and then please forget about it, otherwise you'll drive yourself mad. Yes, it can be particularly bad with TV, but blurays/DVDs/films also suffer variation. IIRC, I think Indiana Jones was supposed to be a really bad one.

Just calibrate, and it will be good enough, for most of the time.

On the subject of using music to adjust audio sync; I dont know if it is just me or if it is in fact true.

Several times I have noticed that on the Hell Freezes Over DVD's DTS track, Hotel California, whenever the camera pans out, the audio goes out of sync. For all the closeups, it is perfectly in sync. Someone please tell me that they have also noticed this! I did not pay attention to other tracks on the DVD as much or it was not noticed.

So if someone used this much loved disc and track, it would be possible to have two different sync settings depending on which section of the track is used.

I've never seen that title, but I've seen it happen with other blurays/movies. I am trying really hard to remember a specific title that had a scene that was pretty out of sync . . . come to think of it I think one was Band of Brothers. It might have been an interview or something with a considerable sync difference compared to the rest of the episode. It just happens.

On other concerts, yes. But I've haven't seen that title either.

Good to know that for once it is not all in my head .

Unbelievable! You probably have... we AH consider it reference media.

^ Is the Blu-ray version out yet?

 

[Lordoftherings]

I guess not.

Thanks for everyone's help and advice. I used the DVE Calibration disc to get it as close as I could. Now I'll let it be. (This definitely can drive you crazy. At my worst moment I actually told my wife that she looked out of sync when speaking only 3 feet away.) Anyway, I'm glad I found this forum, I have quite a bit of reading to do before I upgrade my system.

Perhaps you have a sight problem . You need a GPU upgrade .

I think your best bet is to get the distance from your listening position to your speaker and then divide it by the speed of sound.

With a calculator you can come up with the time it takes for sound to reach you from each speaker. And then adjust all channels withing 1 ms of each other and you are golden.

Math really is our friend.

I was going to say the same.
