Can anyone speak thru low quality QuickCam Audio ?
I can hum a song but speak?

RC said> QuickCam Audio works (yea!), although the sound is not the highest
quality. QuickCam provides 5khz sampling, and the present implementation
simply interpolates that up to 8khz so it will go thru the encoders as they
stand. Puffing up the bandwidth utilization at the sending end by 8/5ths
is clearly a sub-optimal idea, but to interoperate with everything it was
seen as a necessary mode and a starting point.

SetUp

1. Station 1
Apple Mac IIfx
MacOS 7.5
Quickcam and drivers 1.0.3
CU-SeeMe=810.83b1(68K)
CU-SeeMe 26b/s receive&send max CAP to stay modem ~compatib=

2. Station 2
Apple Powerbook 160
MacOS 7.5
CU-SeeMe=810.83b1(68K)
CU-SeeMe 26b/s receive&send max CAP to stay modem ~compatibl=

3. Connection
TCP over localtalk with 2XCU-SeeMe 26b/s receive&send max CAP

The sound from Powerbook internal Mic to Mac fx is OK
The sound from Macfx + QuickCam Mic to Powerbook is difficult to decifer,
speaking low-pitch helps a bit ;)
