Recording ASIO -> WAVE/MME crackles (Kontakt 2, Samplitud

deepcode · Post by **deepcode** » Sat Jun 23, 2007 4:37 pm

Hello,

I tried to set up a environment for Video Sound Design. Main - System is Samplitude 8, Source for Sound FX is Kontakt 2 / standalone.
Here I can create and process / pitch Sounds extremely fast and well. The Idea was to record the single Sounds with Samplitude, routed over my pulsar 1 system.
While the realtime ASIO output from K2 sounds perfect, all recordings in Samplitude have heavy crackles, like a very old vinyl.
I tried to get higher buffers (in the Scope driver settings and in SAM), but without success.
Playing / Playback sound on the MME drivers however is no problem, works perfect, its just the recording which makes trouble.
I additional tried Audition 2 and a small recording app, but with the same result.

Anybody there with a idea what to do ?
Is there any possibility to use more Programs with ASIO at the same time ? I tested it, but It seems to be impossible with the standard settings.

Config: Pulsar 1 + SRB, Scope 4, WinXP, Asus P5B, core2duo E6420, 4 GByte RAM

If you dig under the hardware properties tab in the 'Sounds and audio devices' control panel and choose the Pulsar1's properties, or choose it's properties from Device manager, you will find a tab that has options. One of the options is an 'output preload' slider, plus you can also set the number of wav & midi 'software' drivers available there. Make the Output Preload slider HIGHER and see if this solves your issue. Ignore the 'preferred bit depth' option as it's a carryover from the 16 bit windows wav driver era (Win98/ME).

BUT, can't you load Kontakt2 as a vsti inside Samplitude? This is by far the easiest & most preferable route for sure.

> .. Make the Output Preload slider HIGHER ..
thanks, but this I tried at first. No success. Seems to be an general driver issue, as this problem appeared on my old system too and I hoped to get rid of it with the new machine but no ..

Anyway, more Ideas still welcome!

thanks in advance!

I've had issues recording via the wav drivers in the past too. Output preload & ULLI combined were how I've always fixed it. But again, why not just use Kontakt2 directly in Samp as a VSTi? Or are you just trying to get wav recording to work?

yes It would be cool to have a completely free routing, this is one of the very cool things in scope - I often work with many different applications and so It would be nice to have a simple workflow e.g. to record any output of everything.
Now I use logic 5.5 as host and do the recording there, it is a bit unconfortable but works well.

Does anybody know If the MME / ASIO drivers / cooperation in 4.5 are better or is 4.5 just more DSP plugins ?

thanks.

Version 4.5 is in fact just more plugins
you cannot have 2 (or more) applications using the same Asio driver - that's beyond Asio specs.
and beyond the specs of the OS anyway... or would you really expected it to be that smart ?

cheers, Tom
ps: I know there's this audio-jack thingy in Linux - but that doesn't make it a smart OS either... for other reasons

Actually some ASIO drivers are multi-client, but they achieve this by having the driver allow access to each output independantly. Disable the output (or input actually) in one application that supports this, and another application can 'see' the asio output (or input).

This came along after the v2 drivers were working in Scope. Something to request for the future platform I suppose.

the common interpretion of 'multi-client' by manufacturers has been that one application sees the Asio part, another one sees WDM.
Not even RME could do the trick you describe, which is btw exactly what any reasonable person would expect from 'multi-client'.

Possibly things have changed during last (couple of ?) year - as I have not checked this feature for at least that time.

cheers, Tom

Actually, RME has done it for several years. My multiface does it fine

set samplitude's priority to "above normal"(cntrl-alt-del/processes/right click on sam/set priority).

tried it, but no success.

I also tried to use the STS 3000 or 4000 now as audio recorder within scope, but this thing does not sample on my system!

But maybe I can fix this issue, new thread on STS talk for this.

thanks @ all!
