Any tips on how to lower that? Maybe an option to lower the sound quality a but or something?
I don't use FL but lowering the sound resolution can be an easy fix but never a good idea as u miss out important parts of ur mix, eq is next to impossible (unless u wanna keep re-exporting in hi res listening back, then tweaking again in low res - can be well frustrating!!)
best upgrade ur pc mate
edit - there are ways to optimise ur pc (cleaning up ur hard drive etc etc) but I did this once, followed this guide in music tech magazine, and I could hardly notice the difference on the effect of my programs performance really if u have a good processor and a nice chunk or RAM u shouldn't have this issue
If it doesnt happen in your headphones then it's not a case of cpu power but something to do with your speakers. Maybe this magnetic shielding goes haywire as some other dude said or they could even be broken. Lack of cpu power presents itself as stuttering or sudden drop of audio.
Anyway, you can test if enlarging the buffer size would help, press F10 and click audio tab and adjust buffer length to the right, maybe even maximum just to test things.
