Audio Stream distorted when passing audio streams to/from mac andpc

[BackBayChef]

We are having the oddest problem. We have a video conference room of
sorts, where a main moderator has video/audio to all other users. All
other users can press a button and use an audio stream to talk with the
moderator and others. This works perfectly when using pc to pc. But if
we have the moderator as a mac, or users as macs, the audio stream
becomes distorted when recieved by the mac.

It sounds as if the sample rate is being changed on the mac to a lower
sample rate (as if "satan" is talking back to you).

Has anyone every encountered this?

We are using FCS 1.5, Flash 8, no components, just a normal netstream
publish.

So:
PC to PC = fine
Mac to PC = the devil
PC to Mac = the devil

Thanks,

Macs have a problem with the default audio rate, 8 I believe. Use setRate() on
the microphone to change the rate. Just bump it to 11 for example. You'll use
a little more bandwidth but will have better audio quality and no distortion on
the macs.

would this account for why their stream comes in sounding weird when
they are on a pc sending audio to the mac? I mean wouldn't their audio
sound normal then?

Thanks again,

This is a known bug in Flash Player 8 on the mac. cmowers is correct, use setRate(5) or setRate(11) and that should clear things up.

Hi there, I've been having exactly the same problem. The only problem now....
How do I implement your solution? Where do I change the setRate() for
the microphone? Is it in a component? I'm new to this!
Thanks... Ronnie

Are you having exactly the same problem?

Normally, when creating a communications app without using components, you'd
have some lines of code to set up the microphone, camera, etc. and that's where
you'd implement this solution.

//get the microphone
var user_mic:Microphone = Microphone.get()
//set the audio transmission to 11khz
user_mic.setRate(11)

Thanks for that, You're right! Slightly different scenario. Flash media
server2, and a video chat app using components, but the results between PC's
and macs exactly as described. Since I posted, a friend has fixed the app
although I don't know how he did it. Thanks for you help.
