Helix CPU Usage

Recommended Posts

Hello all, a few questions on the cpu usage I often read about in patches 

Are there any adverse tonal downsides to using to much CPU ?
is there any wat yo see how much CPU your given patch is using ?

How would  one know if using too much CPU  would there be tonal clipping of sorts ?

 

Thanks all for clarifying

Hi, again,

 

Well, if anything you want to add to a signal chain is “greyed out” and not selectable, then you have run out of DSP (rather than CPU). Other things may still be usable, because they don’t need a much processor power. None of this has any effect on the tone, simply because you cannot select something that would push things over the edge.

 

For the scientific detail you should have a look at forum user Malhavok’s (Ben Vesco) listing of DSP allocation in Helix.

Hope this helps/makes sense

Clipping isn't really associated with DSP usage.  If it were possible to overuse DSP it would result in latency not tonal impact because it would still be performing the mathematical transformations required for the model, it would just take longer so that latency would be apparent.  That's why it's controlled.

Sorry, but that is just not the case. A real time DSP has hard time constraints. If not all calculations are done, it has to break up and restart with the next sample. What that would sound like is not trivially predictable.

Well, I wouldn't happen to know in which scenarios it happens the way you're describing things, but in, say, a DAW (which isn't the worst comparison IMO), as Schmalle already mentioned, it's not even remotely as you say. In case the CPU isn't able to process things in time, you will not experience higher latencies but audio dropouts and the likes - which, at least sometimes, do indeed sound a tad similar to clipping (well, we could possibly agree to call it a "heavily degraded sound experience" or such).
