Okay, to preempt the obvious "Google is your friend" response (a phrase I have a problem with on SO many levels, btw), I've done the obligatory web searching...but here's what's going on... My friend and I just started a podcast (in case you're curious, Pie Factory Podcast, available in iTunes...long story VERY short, two retro arcade games per episode)...and there's a major quirk that's annoying me... Now...we talk to each other over Google Hangouts. I plug a pair of headphones into my speakers. I can hear him fine. We each record ourselves and we later sync our recordings together. I'm using the latest Audacity on OSX Yosemite with the latest updates installed. Mid-2011 iMac (details in my sig or description or whatever). I'm using a Zoom H2 Handy recorder as a microphone. Again, I can hear my friend fine in real time, and he hears me fine in real time, but I don't hear MYSELF fine in real time: I hear myself over my headphones about half a second later; I sound like an announcer at a local baseball park. Of course, the recording itself is fine, but...it's very annoying to deal with this. Output device is set to Core Audio. Input device is set to the H2. Right now my only solution has been to just turn the monitor volume down in Audacity. - Hardware playthrough in the Audacity prefs does nothing. Checked or unchecked, there's no difference. - Software playthrough -- the "latency in audacity" search turns up a rash of hits, each saying to disable software playthrough. If I do that, then I can't hear ANYTHING. - The links I find all say disable software playthrough and enable the "Overdub" option. Again, I can't hear ANYTHING if I do that. (And what good is the "Overdub" option when I'm only recording one track?) - changing the number next to "Latency correction" has zero effect. No matter how small I make it, the delay is still there; no matter how huge I make the number, the delay is still about half a second. The only solution I could find was to use GarageBand instead, but even that has its own problems: my voice is chorused as I record, but reverbed when I play it back despite having no effects applied...ughhh... Thoughts?
