Perhaps the following info is interesting for the forum:

I have done some tests with the palantir 2.7 -running as server on Asus wl-500gP- (in conjunction with the Windows client) audio duplex feature.
I found a Philips USB Digital Speaker System that outputs the 8 kHz sampling rate audio ok unfortunately with increasing delay whereas the audio input (e.g. webcam mic) does not show any delay. Interestingly this delay is not present when using palantir 2.7 as server on my Ubuntu linux box. It looks like the Asus wl-500gP is too busy with output audio (speakers) versus input audio (webcam mic) for whatever reason. I think as the Philips speaker set takes directly the 8 kHz audio stream no upsampling is involved at the Asus side. - Upsampling is said to be more CPU consuming -. So why the delay on the output audio? I asked this also the palantir developer.
Maybe someone has any idea? Has anybody else tried this audio duplex feature of palantir?
