Garbled Sound On Recording

[Bill Colbert]

I am having a problem recording an acoustic guitar rhythm track, even when no other tracks have been recorded. When I play back the track I recorded, it has a warbly sound, kind of like when you drag your finger on a turntable from time to time. I get this same sound if I move my mouse rapidly while playing back audio wave files; the more I move the mouse, the more exaggerated the effect is. It is not popping or dropping out, just warbly. I get the same result using both n-Track version 2.1.4 and Cakewalk Music Creator. Could this caused by a too slow hard drive?

Here is my equipment:

Pentium 200 MMX
64 Meg 66 bus DIMM RAM
SAMSUNG WA32162A EIDE Drive, 4500 RPM, 11ms seek time, set to DMA transfer mode
Trident SVGA card set at 256 colors, 640 X 480
Old Panasonic C1395 Monitor

Sounds like you have a soundcard that doesn't support record/playback. If you deselect record does it play back correctly?? i.e. does it only happen when you are in record mode?? Check Option/audio/advanced and select simutaneous record/playback. I think your puter is a bit too slow (HD mainly) to playback full signal and record at the same time.

cheers

Thanks, but it does it evn when I am not in the record mode. I can be playing back a wave file and if I move the mouse, I get this sound. I did get a 4.3 gig, 5400 RPM HD and I am using the DMA transfer setting. This helped with my occasional dropout problem, but I am still getting this garbled effect when I move the mouse. Any more ideas?

The fact that it seems to correlate with the movement of your mouse, could be a sign of an IRQ or interrupt conflict. I just finished helping a friend convert his studio from analog to digital and we had to change some IRQ's in the bios. The symptom we were having was that the midi and digital audio started to separate in timing during playback. This was more pronounced when the "Track" screen was minimized or maximized which required mouse action. I would take a look at the IRQ's

It turns out to have been the video card/monitor combination being too old. I changed from 256 colors to 16 colors and the problem went away. the graphics are not so hot but that's okay. The recording seems to be working fine now. Thanks
