Hardware DSP Effects

thomasabarnes · Jun 14, 2004, 06:39 AM

Hi all:

I've been reading about some mention that the kx compatible cards have hardware based digital signal processing (DSP) possibility. I would love to save my cpu power for other things. So, I have some questions about what available effects are hardware based. It will be great to have EQ, Reverb, and a compressor that's hardware based in the KX compatible cards!

What effects are hardware based in the Audigy (model SB0090). Is Max M's Reverb R a software based reverb? What effects available on the right click menu of the KX DSP are processed by the Audigy (hardware), and what effects are processed by software means? Is the APS Compressor effect software based for an Audigy card user?

My objective is to use the available DSP hardware based effects to save CPU power. Any help is appreciated. Thanks for any comments.

Sincerely, thomasabarnes

All the available effects in KX DSP window are hardware based, including Max's Reverb! That's the beauty on them!

unfortunately the current batch of UFX will be incompatible with 3538… until max updates them

Hiya Daniel Drummond:

You say all the KX DSP effects are hardwarebased. That is indeed fantastic!

Sorry to sound stupid, but does that mean I can use the APS Compressor even though I have an Audigy soundcard, and the processing of the compressor will be done by the Audigy hardware?

Sincerely, thomasabarnes

Hi!

Not fully, a part of aps-compressor lies in the DSP, another will be calculated by the CPU over a *.dll.

i think that is due to the fact that there needs to be a constant register, instead of the same thing being calculated 48 thousand times a second (this will change soon

)

Thx for the info Gents.

Yes, you can use the APS Compressor in the A2. No problems. And yes, some calculations are done by software but as far as I know, those are really, really light as the heavy processing is done by hardware DSP.

Cool, thx Daniel D : )

What I see here is that there is some misunderstanding about what the role of the emu10kx digital signal processor(DSP) actually is.

All the realtime digital signal processing (in our case the signal is sound but generally it might also be any other type of signal) including sound effects is performed by the DSP. Generally the role of the CPU is to perform calculations on the effect parameters, so the load it gets by doing so is very very small.
