Audio Delay

[ucphinni]

Add a setting for millisecond delay to audio similar to VLC.

If desynced audio is a system-wide issue, it’s worth checking if your audio driver allows you to add a delay.

Alternatively, you can install the Equalizer APO utility – this allows you to add a delay (among many other things that could potentially be useful) and uses minimal system resources.

Checked the audio driver, it does not.

However, I am not at the kingdom hall and if Equalizer APO works the way I think it should, then that is exactly what I need. Been searching the internet for a while for something like that thanks. Wonder why Windows MPC and VLC have audio delay built in?

I imagine it’s included for when the issue is caused by the file’s audio track actually being out of sync with the video (as opposed to it being caused by any hardware-related factors).

Equalizer APO is very lightweight so shouldn’t cause you any issues.

Thank you. I installed it on the kingdom hall computer via teamviewer. My meeting has been moved to today due to CO visit of another congregation so we will have a live test. I will close this if it works.

Once again, thank you for your suggestion.

@Blann This is a useful tool - I'll add a link somewhere. Thanks!

Hey, this works!

This is a very common problem in kingdom halls all over and I see it when going to other kingdom halls at least in my area.

Normal setup: Audio gets split from computer hdmi to sound system via rca channels and tvs through sdi/hdmi converters.  Sound system speakers get the signal about 250 ms second before tvs.

You can even hear it when tv volumes are on as an echo and see it with lip sync.

Changing the delay eliminates the echo.

Once again thanks.

Changing the delay does not eliminate the echo (I was not close enough to the tv, but allows proper lip sync with audio system and tv video which is what the friends want.

[AntonyCorbett]

@ucphinni if the TV speakers are on then that will account for the echo

[Blann]

Yes, it won’t eliminate the gap between the audio from your sound system and from your TVs because they’re using the same output device from your PC. The signal is just taking longer to reach the TVs.

@ucphinni, You could run the audio straight out of the sound card instead of out of the HDMI, change your default audio device to your sound card if you do so. This will eliminate the audio being transmitted to the TV's in the first place. Or better still if you have a newer digital or hybrid mixer with USB input, run a USB cable to the mixer, and change it to your default sound device.
