emu10k1 effect processor

emu10k1 effect processor

[Patrick Dumais]

Hi,

Could any one point me out where I could find information on how to
control the integrated effect processor on the Live card with an alsa
programming interface? and possibily how to make my own modules? I know
there is an assembler for that, I found a couple of links. I just want to
know if someone has a specific link to recommend.

But I am mostly looking for specification of how to use emu10k1 effect
within my alsa application

Thank you

Patrick Dumais

Check out Peter Zubaj's ld10k1, http://ld10k1.sf.net.  It now has a GUI,
qlo10k1, and a C library interface to the emu10k1 DSP.  It is still
under development and is not as advanced as the kX DSP, yet.

The other emu10k1 utilities are for the OSS driver, ld10k1 is the one
you should use.  They might have some features that aren't yet in
ld10k1, this project could always use more developers.  Currently the
Windows emu10k1 hacker community is much bigger than Linux, due to the
kX drivers being better than the ALSA driver.  I am one of the people
working on this.

I see.

So the only way to use emu10k1 effects is to load them with a loader only.

I had in mind that I could do something like this:
snd_loadEmu10k1Effect("./vibrato.bin");
snd_setEffectParam("vibrato",PARAM_VIBRATO_FREQ,20); // to set the
frequency of the vibrato effect to 20hz

anyway, something similar.

I want to be able to at least control the effect within my app.
I currently have an effect processor in my soft-sampler but I wanna let
the hardware take care of it, but I don't wanna lose control over it.

Hi,

>snd_loadEmu10k1Effect("./vibrato.bin");

ld10k1 contains library and you can load effect to dsp with 2 function
calls + some function call calls to connect to ld10k1. But effect is
program and needs inputs and outputs, and this you need tell to ld10k1
too.

>snd_setEffectParam("vibrato",PARAM_VIBRATO_FREQ,20); // to set the
>frequency of the vibrato effect to 20hz

You can export effect parameter as controls. These controls are
acessible through standard alsa mixer api.

It even has a GUI now.

You can do this, this is exactly what the library part of ld10k1 does.
