Subject: [AVT] Query on Audio stream clock tolerance

Hi,

I am new to this area. Could someone help me on the impact of clock speed
variance on Audio Quality. Let me explain the scenario.

Originating source smaples voice at (8Khz - 100ppm) clock rate and produces
a 64kbps digital stream.
The data gets transmitted over IP to the Receiving end and is played back at
(8Khz + 100ppm).

The scenario is for a PC to PC communication using RTP as the media
transport protocol.

My question is, what would be the effect of this clock speed variance on the
voice quality both in forward and reverse direction?

Thank you for the help.

Regards,
Subhas
