[linux-audio-dev] Linux kernel HZ, audio latency and how to measure?

[Mulyadi Santosa]

Hello everyone....

I am kinda interested to study the effect of changing kernel HZ 
(internal timer frequency) and the audio processing. Since I am a 
newbie in Linux Audio, I will be glad to receive any comments, 
especially the constructive ones.

Is there any relationship between kernel HZ and audio timing? I imagine 
that something like audio recording from a Hi Fi will get a benefit 
from a finer granularity timer frequency, since it can achieve 1ms (or 
even smaller) resolution. But, if there is relationship between those 
two, then how to measure it? Do I need to check every delay function 
and record the requested delay vs the actual delay? Or is there other 
method?

I already searched the archieve looking for the similar question, but I 
found none. 

Thank you in advance your help and attention.

regards,

Mulyadi
