Subject: What is the required accuracy of audio sampling rate?
Date: Tue, 16 Feb 2010 15:58:59 -0800 [thread overview]
Message-ID: <e5baf3861002161558x1d36f74anf63c5db145762668@mail.gmail.com> (raw)
Hi,
I have a PCI-e audio card that does not give very accurate sampling rate
(about -0.2% error, i.e., if I set the sampling rate to 8K, I got only 7984
samples per second on average). It caused various synchronization problems
in applications like gstreamer.
Since there will be some difference from one clock domain to another, I am
wondering if there is any defined tolerance on the sampling rate, and where
the right place is to correct this kind of error. I would really appreciate
if someone can point me to the related documents/links.
Thanks,
Yiliang
