Is there an easy way to measure a VST-DX plug-in's latency in samples?

Thanks

I'm sure there is but I don't know how. Personally I do it the hard way and record to audio then zoom in and look in the audio editor for msecs.

Interestingly enough I was exporting a drum group a few days ago - I was quite horrified at the delays I got - putting the drums through the Triplecomp from Sinus (I must buy that - a lovely comp) and some TC Eq, I got a delay of just over 20mSecs. I think alot of that was from the triplecomp (it uses read ahead for peak-spotting), but it certainly put me off using my group channels as much for running stuff directly to the final mix - After that I started to render all the groups to audio to get rid of the delays. I hate to think what the delays are on some of the other plugs!

For read-ahead plugins for example, Waves L1 or L2
measure latency usually impossible becuase delay is inside
algorythm but:
make wav file, with first sample is impulse with amplitude 0dB,
load sound forge, apply plugin and you will see latency in zoom mode with
and select samples as show units.

As for plugins based on Fast Fourier Transform, you can easy calculate latency withL FFTsize and Overlap value:
for example, FFTsize = 1024, Overlap value 4 or 25% usually (overlap 2=50%), So latency= FFTSIZE-FFTSIZE/OVERLAP = 1024-1024/4 = 768 samples. You can try that method with impulse as well.
Good luck
