[Alsa-user] period time/size - buffer time/size

[jakob k. <jak...@ho...>]

Hi
I try to understand the asound.conf options. In some plugins like dmix and 
dshare I can choose a period time and a period size as well as a buffer size 
and a buffer time. What is the technical meaning of this options?
I read something about the buffer stuff - is it right, that buffer size is 
the size of one data package that is sent to the sondcard at one time, and 
that buffer time defines how often new packages are sent to the output? If 
yes, what is that period stuff for?
I hope, that anyone can explain this to me. Does anyone know a good text 
online, which describes how a soundcard works and how it interacts with the 
software. I didn't find such a text but would like to get a better 
background, so maybe one day I know what I am doing when I change audio 
options.
Whish you all the best

Jakob
