Microphone rate capture doesn't work correctly on MAC

Question

Hi everyone,

We have a sound issue with Mac users that use our
videoconference app.

Here's the problem: publisher of stream(audio+video or audio
only) can change is microphone capture rate(in kHz) using
Microphone.setRate(). If, and only if, the OS of the receiver user
is Mac the sound will be ugly(like a bear speaking in a headphone)
when the rate capture is at 8 and 11kHz. When the rate capture is
5kHz, the publisher seem to speak like Speedy Gonzalez(Buggs Bunny
cartoon). Sound is correct when the capture use 22 and 44kHz.

This work perfectly on PC and this "thing" only happen to Mac
user. The problem is not related to bandwidth(40mBits available) or
performance(G5, iMac had same bug). Video is fluid it's only the
sound at capture rate of 5, 8 and 11kHz that bug.

We use FMS and Flash Player 9 on all computer either Mac or
PC.

Thanks for your help!!!

There is a problem with the Flash player on Mac, but it canbe fixed by setting the buffer on a netstream. Player for Macversion has always been like this. You can trynetstream.setBufferTime(.01). This will solve your problem. Flashplayer on Mac requires you to set the buffer time although verysmall.
