Just wondering what could cause DSP spikes when just importing raw tracks with no plugins. I’m on 4096 buffer snd dsp is like 1 percent to 3 and then 16 then back down. It’s not a big issue just wondering what could cause that.
I’m using a lll my cpus in settings and high performance mode on my workstation.
Is there anything I can adjust in settings to make things more stable.
I was previously on a session at 96k with minimal plugins and dsp would go into the 60s etc snd I would be worried since when I start mixing if it will t worse even at higher buffer settings. Think it was 2084 at that time.
I had something similar which turned out to be because in Ardour’s ALSA settings I had accidentally selected ‘default’ for the ALSA interface. ‘default’ was / is actually not a real audio interface, but, instead Pulseaudio pretending to be an ALSA interface. Because of the way pulse does what it does this caused erratic latency variations and DSP demand spikes. Switching instead to the real audio interface solved the problem.
I wasn’t using JACK at all. Perhaps I’m mistaken, I was sure that was the reason. I definitely had DSP spikes with no plug-ins, just a basic audio track - in that case I can’t remember what was the cause, or, maybe I just reverted to an earlier version for the testing I wanted to do.
