| BrianHechinger[m | What is a reasonable number for the DSP to be running at under minimal load? (ardour, no other jack plugins/applications) | 07:32 |
|---|---|---|
| rgh | Brian Hechinger: dsp load is how much of the audio buffer is used | 08:16 |
| rgh | So it totally depends on how you set up your audio backend. | 08:17 |
| rgh | Please remember that low latency / small buffers is only needed when monitoring your audio during recording. And only that if you don't monitor through your hardware sound device. | 08:19 |
| rgh | Since I hardly record / monitor live audio / midi I use a fairly large buffer (1024) and my dsp load is about 2 to 4 % | 08:21 |
| BrianHechinger[m | I only ask because I'm playing with Liqourix and I can now run 32/3 which uses 20% DSP (64/3 only used 10%) and unless I'm misremembering on the old system even 16/2 wasn't using that much DSP. | 09:17 |
| BrianHechinger[m | 12% with 64/3 (had to drop down due to xruns) | 17:39 |
| BrianHechinger[m | so, I guess 20% isn't too far off base. | 17:39 |
| rgh | Brian Hechinger: I've never got lower than 256 I think | 17:41 |
| BrianHechinger[m | I couldn't reasonably get below 256 with USB audio. FireWire FTW. :-D | 17:43 |
| OvenWerks | BrianHechinger[m: if you are doing firewire using the alsa drivers, 256 is pretty much minimum. The same device using ffado drivers will do 16/2 solidly. USB devices must have their own irq and a clear USB bus. Many new mother boards will not allow this at all. The only way around may be to add another USB port with a PCIe card. Also, whichever USB bus you are using needs to have a higher priority | 21:58 |
| OvenWerks | than your mouse, webcam, etc. | 21:58 |
