[PD] Tweaking audio settings

Hi

I just installed a Delta 410 card (like Delta 1010Lt but with fewer Ins) and am using the latest ASLA driver. For the first time in several years I need to tweak the audio settings when I run PD, otherwise I get glitches (DAC blocked DIO errors and spikes in the sound).

I have been experimenting with the options:

-audiobuf -blocksize -frags -fragsize

...and found that -audiobuf with a setting about 100 works well. In my book this should add a horrible latency, but I cannot notice it (I use a graphical application of an exploding firework to trikker playback though netsend, so I use 'visual' latency measurement).

My question(s):

1. What does a audiobuf size of 100 mean in terms of latency (how many

samples or ms are we talking about here?)

2. What does the other audio settings mean?

TIA
