[music-dsp] Graphics and sound sync

[Andrew Greenwood]

How would you synchronize graphics and sound, for example in the case of a
level meter?

It should be fairly simple in an audio player, but what about for a
near-realtime performance program?

As graphics are updated immediately while sound isn't, how do you compensate
for the delay? Mainly, how do you get the graphics to animate at the correct
time?

If that makes any sense...
