What's the downside to larger jackd buffers?
I usually use a hardware recorder to capture my audio and then I edit it in ardour. Thus I've never cared about latency and xruns. As a matter of fact I've never really understood what it is. I'll see some xruns in the jackd terminal window but that doesn't seem to affect the quality of the exported audio from ardour so I haven't cared.
Now I'm starting to record some audio directly into the computer and jackrec will halt if there are too many xruns.
The jackd man page says I can decrease the number of xruns by increaseing the -p and -n options. I just did and the xruns seems to be gone.
Now what is the downside to this? What exactly is latency and why is it so important to have low latency?
