It seems GB is sensitive to when you plug headphones into the jack. It's better if you plug them in before starting GB. Otherwise, it seems to get really weird. If you're running GB, unplug headphones, and then plug them back in, you can get latency in the 2 to 4 second range. Close and restart GB to nearly eliminate latency.

(Occasionally some application will be running on the MacBook that will cause GB to hang for an instant. This can cause latency to jump. Restart GB to fix it.)

Simple effects such as Podcasting microphone effects (Male Narrator for instance) cause minor latency. Significant effects, such as the Vocal Transformer effects, take more processing and result in greater latency. While I've not done a formal measure, those effects probably result in 0.1 to 0.2 seconds of latency. To avoid stumbling over your words, listen actively to your spoken voice, and hear secondarily what's coming through your headphones.

Hope this helps!
