Wav files saving CPU?

| I'm currently working on a project which contains quite a lot of Vst's, Z3ta being the main one. I have a ty soundcard so the CPU is redlining to the max. If i render each individual Vst pattern into a WAV file, is it true that it will save me some CPU? Sorry for the noobie question, i'm still getting the hang of things... :) |

Yes.
By rendering to an audio file, your computer has only to read a simple audio file rather than your CPU having to perform all the calculations to make the sounds your VST instruments and effects are producing. You can also try freezing a track if your DAW software supports it. Track freezing is exactly the same thing as rendering to audio. |

Ok, thanks very much Eric! :D |

ASIO drivers did make a difference, though CPU was still sky high unfortunately :( |

A better soundcard will give you better sound quality, more inputs/outputs and so on, but won't help your CPU usage at all.
To get better CPU usage, get a better CPU or get some cards (like the UAD or TC Electronics ones) which run plugins off them. |

?
Yes it will.
ASIO4ALL is far from efficient. At the same latencies, a proper ASIO driver will chew up way less CPU. |

A better soundcard will get you a lower latency without it using as much CPU time.
So yes, a better soundcard with proper drivers = saving on CPU usage.
To the OP: how come you didn't just try it for yourself? I don't mean to sound like i'm taking a direct stab at you but was it really easier to log onto TA, make a new thread than it was to just press the freeze button and look at the CPU meter? |

i tested this theory on fl-8 with both my onboard ac'97 audio and my m-audio fast track pro.... i nearly maxed out my cpu (96%) with a bunch of instances of absynth 4 running chords on a complex atmosphere preset.
the same thing running on my fast track pro was an astonishing 1% lower cpu useage.
its all about cpu power when running vsts. recording audio is a different story

I've done a similar test on cubase about a year ago and it made about a 15% improvement.
You're right VST's are going to cane your cpu regardless of soundcard, but it is a factor in overall cpu usage. You computer can only work as fast as the weakest link in the chain. |

| Rendering will save CPU, but may tax your hard drive more in some cases. Its a tradoff that usually comes out OK for dance producers, since most of the stress is placed on CPU by VST instruments. But if your HD is slow, or your recording a lot (esp. in rock) then you might find it makes for dropouts as your hard disk gets overloaded. |

I suppose I could of...
Anyway thanks for the help everyone, much appreciated :D |
