Facetime for computer audio quality

I haven't yet, but FaceTime for the Mac is a BETA.

Copied from your previous post.

*The problem doesn't seem to be hardware specific since our conversations on Skype work fine.*

You've answered your question. If this were hardware related, the same would happen with Skype and iChat, and your wife can hear you fine. It is a BETA.

Having the same exact problem, only with me on an iPhone 4 and using FaceTime with a Mac. It actually worked perfectly for about 20 minutes, and then just as you described - video was fine on both ends, audio could be heard on the Mac, but only garbled/mute on the iPhone. Every minute or two it would come in again clearly for a few seconds and then cut out again. I've used FaceTime before, as well as skype on this Mac unit, so I don't think it is a hardware issue

I also experienced that same thing, I could hear and see the iPhone user clearly but they could see me but not hear me. We have had no trouble using Skype. Must be a beta glitch.

Actually, I've found that audio quality is quite excellent, with extremely low latency compared to other VOIP offerings. I don't know what technology Apple is using, but the latency on FT is rather low: about 200-300ms (vs 3,000ms typical for Skype).

Of course, I should say I have a fast cable connection (20 Mbps) with low measured latency (60 ms), and the video/audio load of a FT represents no real burden (about 120 kbps). Obviously, your results will vary, depending on the upload/download speeds of the wi-fi systems at both ends of the call.

It's a good idea to verify the connection speed when using wi-fi: there's a number of free bandwidth testers available on iTunes app store that are worth running before attempting to place a call, as the quality of the connection is directly tied to voice/video quality.
