Effect like "24bit Crystalizer" from X-Fi in kX....

VANT · Oct 9, 2005, 02:40 PM

I hear that this effect is like compressor.......What You thing...How we can make this effect in kX..??

kingme · Oct 11, 2005, 11:02 PM

There's already a compressor/dynamic processor?

Rogacz · Oct 18, 2005, 02:08 PM

I believe it's more advanced that this compressor in kX.

VANT · Oct 18, 2005, 03:10 PM

i belive that this effect can be relized in kX....

you should have clear in your mind what you want to make before makin' it...

Look into the many reviews of the x-fi. In at least one of them I recall reading that this effect already existed before in at least two commercial products. It explained a little what this effect does. I don't remember which review it was.

EDIT : found the link http://www.digit-life.com/articles2/...tive-x-fi.html

As far as I know it's not dynamic, so it doesn't change for each audio source, what means it can be done for kX.
But what CPU usage will be after using it?

if u use a dsp effect on your card you are not using the cpu for that effect!
the effect is on your card's dsp.

Rogacz · Oct 19, 2005, 04:42 AM

Hm, so the question is - will the cards resources be enought for such an effect.

You can build a multiband compressor. I can think of using crossovers and the existing compressor right now and should be fine without loading much other efx.

Yes, Ive been experimenting with that too.

The DSP gets a bit messy/confusing - which makes tweaking a bit of a pain, compared to a single interface like in Waves LinMB say, but yes... possible with out draing too many resources.

I cant compare it to what the crystalizer does, as I dont have an X-Fi to play with, or RMAA to test with.

It would be nice to have a single KX plugin to do this, I wish I was a better programmer.

- 'Some day Danial-son... some day'

Update:

4-6 bands of MB compression are easily do-able. (Using APS compressor's)
But I just noticed, trying to use 'LOSHELF' EQ plug in - doesnt seem to work.
Is this a bug in 3538h? - or am I doing something wrong?

@Maddogg6
Any progress in your kx_crystalizer??

@Trill
Maybe You can try make this effect......??

...still loosing time on Crayola Labs Bullshit? Every time i see enthusiastic people about new stuff comin' out from Crayola Labs i think: still waiting some serious stuff?
Do you want to get serious? Get an M-AUDIO... RME.... not Crayola

Tril · Dec 6, 2005, 12:20 PM

I never had any plans to make something that works like the Crystalizer. I don't even know what's the definition of a multiband compressor.

Also, I have never heard this effect and I don't have an X-FI. I have no way of knowing what it does.

Also, the kX cards use 16 bits. I suppose that you need 24 bits to take full advantage of such an effect.

The most important to me :
I heard bad things about the effect. It decreases the audio quality of good quality sound.

Maddogg6 · Dec 6, 2005, 02:22 PM

Im thinking the crysalizer is a combination of common processing (comb or IR filter - compressor/expander - Harmonics exiter/synth etc) in some patented dsp code. I doubt they have broke new ground in the psycho-accoustics field - thats usually them MIT / Bell Labs types doing all the pioneering.

I have not made a MB Compressor module - I just chained modules together within the dsp to acheive a multiband compression - But Trills NEW Harmonics Generator is a sweet addition.

Basically - to accomplish multi-band compression

Split the input signal into (multi) Hi-Pass, Band-pass, and Lo-pass filters and seperate compressors (or expanders - for MB expanders) for each (band) filter - then re-mix with a mixy4x2 or 8x2
Make sure ALL output is DELAYED equally in the eCompressor - they do a 'look ahead' which will introduce 'delay' effects. This was a lesson for me.

I use this (3 bands) JUST before out (fronts only usually).

I also find my self using prologica - its great for TV and stereo upmixing. I use it with digital cable Music Channels as it s A SPDIF out on the converter box.

- But I do find myself 'tweaking' all the time (song to song & channel to channel) - so Im working on an 'All around' configuration. But the sound is great. Rivaling them expensive Bose Lifestyle systems, with these cheap Altac Lansing speakers. And when I use my monitors - fehgedaboudit....

I would be excited to learn more about the X-FI's technical specs.
I wonder how much CL developers crippled ITS potential...

In what way is this new pugin useful?

That Harmonics Generator plugin could be improved (to get more or less harmonics and to lower the number of instructions).

Maddogg6 · Dec 6, 2005, 08:07 PM

Well....
If your asking about your own plugin...
It really helps with speakers with a crappy low end - really brings up the bass in a smooth way.

Multiband compression allows compressing (or expanding) certain parts of the spectrum - and is useful for adding punch to a solo instrument - or in my case compensate for the dips and peaks inhearent in my speaker freq response curves as well as loss from MP3 compression.
If I were a programmer, I'd prolly make a 3 -5 Band MB compressor using exisiting Dane code - just kinda lump em all into 1 module and possibly free up some resources - and strip compressor features I dont use. But Im not - lol. I started looking into it and was distracted by the great sound I get already... so...

I love what I hear eitherway. PLUS its a LOT of fun trying different configs.

Hi, Tril, i think it would be cool too have a low pass filter already implemented in your plugin, and being able to choose what harmonics to generate... in general it would be cool a more complex skin with more controls!

Tril · Dec 7, 2005, 02:41 PM

radiocolonel.it, I thought about it. I wanted to do this but it would have taken a lot more time to make. Maybe I'll do it later. It is more complicated than the current plugin because I have to make a C++ plugin.

Anyone else is free to do it in my place if they want it sooner. The code of the harmonics generator is posted in the forums and the C++ code of the lowpass plugin is in the SDK.
