Subject: Re: [Ardour-users] optimal jack settings for ice1712 From: Jan Depner <eviltwin69@cableone.net> Message-Id: <1055600670.28675.28.camel@eviltwin> Date: 14 Jun 2003 09:24:29 -0500 If you're monitoring what you're recording there will be a delay in what you're hearing that is equal to the period / sample rate (I think) so at 2048 samples and 44.1K sample rate you get a delay in what you're hearing of .046 seconds. This is extremely annoying. If you use a period size of 256 the delay is .006 seconds which is just barely noticeable. If you use an envy24 chipset card you can monitor what you are recording via the card itself thus eliminating this problem. As I understand it the advantage to setting a small period size is that you can monitor with inboard effects. The disadvantage is that you are pushing your system a bit harder and may get xruns. If you use a lot of inboard effects or a lot of tracks this can be a problem. The advantage of the envy24 chipset card is that you can use a large period size which may reduce xruns. The disadvantage is that you can't hear inboard effects on the track(s) you are recording. There's my 56 millionth of a troy ounce of gold (at current market value).
