Hi

I seem to having a little issue with 24 Bit Wave Source drivers. When playing a wav file then stopping it I get an echo effect each time. This only happens in some programmes and it happens with 16 bit and 24 bit wav files. Has anyone had a seemlier problem if so did you find a solution?

Regards

Gary

Hi

It happens when I play back wav files in either media player, Vegas or a programme I use called SFX. It’s not a problem in Adobe Audition 1.5. I think its something to do with flushing the memory out when stopping.

Have you come across this problem before?

Regards

Gary

Yes, it happens here too. Thats the reason why I'm not using 24-bit wave source.

in the task manager, set vegas or sfx's priority to above normal. that should help.

Hi

Thanks very much for your suggestion but I’m afraid it did not fix my problem. If it helps it only seems to repeat on the right hand channel. I would be grateful for any other suggestions.

I think the problem is in driver level (in conjunction with os), as all sources i've tried (soundforge, wmp, etc.) suffer the same symptoms. Unfortunately driver update is improbable.

I had thought the same thing but needed someone else to confirm it. Why do you think driver update is improbable? Do you think there is sny life in Creamware?

Gary

Sorry, didn't mean to say there never will be software updates. But the situation seems (to myself) like there are no resources for further scope development at the moment. Lets hope ASB boxes sell well and things will come back alive in other areas as well.

I hope so too, I think the Scope cards are great. I wish I had discovered then sooner.

Congrats, you found the bug in the WAV driver, gary :> Indeed, the driver as posted in Presets and Tools (?) forum here repeats it's RH buffer 3 times when playback is stopped. Not that disturbing, except for editing short samples (drums?) in SoundForge etc...

Yup Gary, this is a well known bug. I also have it on my system when I stop a wavefile in e.g. Mediaplayer or Adobe Audition. I don't find it that annoying, but ofcourse I wish it wasn't there...

never happens here. lucky, i guess.....

never happens here either.

Are you using win98, W2000 or XP?

xp.

hi

wave driver 24 bit give glitches here

Hi

1st of all thanks for the replies.

Can I confirm something; is the standard Wave Source a 16bit WDM driver?

Is it possible to try and work out why 24 Bit Wave Source works fine on some PC’s and not on others?

Not sure if this help but in the programme I use for show playback which is SFX, by Stage Research. It has an option setting called Flush Buffer (for Win2K if small pops at the beginning of a cue). If the is selected then the echo effect stops. As soon as I turn this off and restart SFX the echo effect starts again.

How can we get this echo effect fixed?

I know if my clients see as an option they will want to use it.

Look forward to any thoughts on this.

Regards

Gary

It happens on my internet machine (I have a Luna2 in it at the moment) with windows media player, it's a Pentium 4 running 98se.

My working machine that has 2 Scope Pro(precisely a Scope Pro and a Powerpulsar) cards and a Pulsar1, doesn't show this phenomenon, but it runs XP on a Pentium III-s.

The Pentium III machine is extremely more stable and better than the other one, the brute cpu power might be lower (1.26 Ghz vs. 2.66 of the PIV) but I don't use VST's, and the feel of the 2 machines is very different.

The problem is that the 815e chipset has memory limitations, fortunately I'm not an heavy sample user, but if I should watch for an upgrade my istinct suggests to stay away from P IV's.

The Pentium M adapter for ATX mobos is intriguing....

I'm afraid I use P IV on all my systems. Is it worth me trying to get Creamware to fix it?

Garyb uses PIV as well, but he doesn't have this problem....I suspect more of a software problem of the windows sound manager is some systems...if some systems don't show this bug it's not something under the total control of CWA.

Maybe an in deep study on 2 similar systems, one with the "bug" and one without could reveal something, some particular conflicting system driver or whatsoever...it's not an easy task.
