Figuring out filter delay

[Ofer]

Is there a way to get the a TTD filter delay? I want to play music videos with TTD filters and manually (possible in VLC) insert delay correction. Is there a menu in AL that tells you the delay the filter inserts?

You can see it in the IR view. You can open the correction and read the timing of the leading pulse that arrives latest. In addition to this, you have the physical distance to the same speaker and of course various buffers in the audio stream. But Lip sync does allow for maybe 30 milliseconds either way, so this will get you well inside the comfort zone.

You will also get a reading in accordance with the above if you open the correction in Audiolense Convolver.

How do I see it in the IR view. In the picture below there are two "active" areas first at about 0ms and the next is at ~680ms. Does that mean the filter introduces delay on ~680ms?

Uncheck everything but correction filter. The zoom in. There’s a zoom function on the mouse
