adjusting Delay effect

Audiophaser · Mar 27, 2003, 04:47 PM

Hi folks,

I'm kinda new at this, I would like to use a delay filter that has only a 'wet' signal as output. With this I mean, I don't want the effect copied over the original sound (resulting in an 'echo' kind of effect), but I just want the effect.

How do I accomplish this?

Regards,

AudioPhaser

Audiophaser · Mar 28, 2003, 09:47 AM

ps: How does the delay percentage work, is it percentage of the wavelength? Can't i set the delay in ms?

TheKezmiester · Mar 28, 2003, 11:46 AM

Maybe Max has a new delay for us soon too? I've never been able to make sense of the time slider in the present one.

Audiophaser · Mar 28, 2003, 12:28 PM

or maybe i can edit the current delay in the DSP editor?(though I don't have a clue how emu10k2 DSP coding works). Perhaps someone allready has code that just outputs the filtered signal?

**Eugene Gavrilov** · Mar 29, 2003, 02:06 AM

the 'delay' effect bundled with the driver is not recommended for usage simply because it is a 'demo' effect
I hope we will write a real 'delay' effect soon

New delay effect would be VERY NICE!!:.

this one is very bad....It would be nice to have real Overdrive effect, and Distorsion.
Chours is pretty much OK..
and those are the most used effects in guitar recordings...

Hanz Petrov · Apr 3, 2003, 05:11 PM

It would be relatively simple to port the APS delay effect to kX - in fact it's one of the last couple remaining to be done (and with Soeren's kickass EQs, there's not much need for the APS EQs :-)

Maybe for the next release.

Regards,

/Hanz

p.s. Eyagos, thanks for looking at the PitchShift - seems like a lower-level (driver) change has helped with the "sound artifacts".

eyagos · Apr 7, 2003, 08:01 AM

Uauuu Hanz.

Dont remember well if I said you that in my computer the orginal effect (for KX) worked sometimes well and sometimes bad. And probably the cause was the 'skip' instruction as I commented you. But it could be too a solar storm...

I agree that Soerens EQs works fine. He mades a good work.

Regards.

Stop all the LEGAL wars.

Blento · Apr 7, 2003, 10:01 AM

Where can I get that Soerens EQs ?

eyagos · Apr 7, 2003, 05:57 PM

They are bundled in the KX drivers. Soerens was the author. About real overdrive and distortion... cant say nothing at the moment.

The APS Fuzz effect is pretty real imho (it's also identical to the LiveWare version) - are we looking looking for something more?

/Hanz

p.s. eYagos, yes now I see that the pitchshift is still hit & miss - needs more study (skip you say?)

Audiophaser · Apr 8, 2003, 12:35 PM

Well, all I really want is to control(via midi) the time it takes for the audio to reach each speaker, 6 channels per audio card(something in a range from 0.1 ms to 20ms).

This is for a school project that wants us to make an Audio phased array (we have about 32 boxes, 3 computers and an x amount of audigy cards). Each box has to have a different delay (very small) so we can accurately direct the sound to a certain location.

If anyone wants to work on this or has any pointers for me, It'd be great

(I'm currently browsing some documents on the emu10k1 assembly and dane, but it's quite hard for someone not familiar with low level programming)

Audiophaser, that sounds like an interesting project!
I too would like to have delay effect with fine adjustment, but for a different purpose.
I'm using kxproject drivers for an active crossover in my speaker-building hobby and would like to use the delay effect for correcting time alignment of the high and low frequency transducers (tweeter, woofer). I'm not a programmer so I don't have much to contribute to the creation of such an effect, but maybe it will have enough utility in p.a. or home theater applications to get attention from the creators.

alvins · May 21, 2003, 05:26 PM

If someone makes this delay effect. I would be very interested. I am also working on a project...for the car..need timealignment to delay speakers so they reach the driver at the same time.

dMic · May 26, 2003, 06:43 AM

This isn't sample accurate, but it works for me:

Code:

xtramsize 24000; (0.5 seconds)

const maxDelay=0x2EE0000; used to scale control value
input in;
output out;
temp tmpIn;
temp tmp;

; UI controls
control delay=0x20000000; delay time
control dryLvl=0x7fffffff; dry signal pass-through level
control wetLvl=0x7fffffff; delay output level
control feedback=0x0;

xdelay write wrt at 0x0 ; write point, always 0x0
xdelay read rd at 0x0 ; read point

; code
acc3 tmpIn, in, 0x0, 0x0;
; scale delay control value to line size
interp tmp, 0x0, delay, maxDelay;
; set read point
acc3 &rd, tmp, &wrt, 0x0;
; set dry level
macs tmp, 0x0, tmpIn, dryLvl;
; read from delay, set wet level, mix with dry signal
macs out, tmp, rd, wetLvl;
; set feedback level, mix with input, write
macs wrt, tmpIn, rd, feedback;

Blento · May 30, 2003, 09:45 AM

where should i write this?...an will it work in latest (33) drivers?

dMic · Jun 2, 2003, 05:40 AM

Yes, it works for me in 3533.

First, right click the kX tray icon and select "kX Editor" to create a new plugin. Paste the code from my earlier post directly below the ;code line. Edit the name line at the top of the file and give it a name (such as "delay2"). Click the little floppy disk icon on the right side of the editor window and save your new plugin. Double-click the new plugin file to register it with the kX driver. It will now appear in the DSP plugin menu under the name you gave it.

alvins · Jun 4, 2003, 06:34 PM

This produces the echo delay, not a full delay.

wilho · Jun 10, 2003, 07:09 AM

Hey this is what I was looking for. Works allmost perfect. Adjusting of delay should be in ms though.

---edit: deleted comment of sound quality, there's nothing wrong with that.

I'm not sure I understand what you mean. What is a "full delay?"

This would be nice, but it is not currently possible with the DSP editor.

Right, ths is what 'plugin dll' (kxl) is for.
DSP should process sound data... But all parameters calculations (and user interface) - all that ms, db, Hz etc. - can (and should) be moved into kxl..
Raw "*.da" code is more for algorithm test actualy - the good plugin is "da + dll' one :) ...
Well, for 'kxl' examples see SDK.

Unfortunately, the SDK requires MSVC++/MFC, which I don't have.
