Guitar Recording Problems

got an odd problem here. Im using Audacity 1.2.6 and i’m having issues reocrding guitar. First of all, im running my Line 6 amp from the record out directly into my soundcard, and when i go to record guitar, for the first 20 seconds or so, its fine, but anything after that has a very compressed chipmunked(?) kind of sound, and the volume level is greatly reduced, thusly rendering the track useless. all my volume settings are at acceptable levels, as i never changed them from previous recording projects, all of which were fine. I have no idea how or why this problem came about. any help or advice would be awesome. Thanks.

here’s an audio example of the problem i am having recording gutar. Thanks again…

When you say it has a chipmunk sound do you mean that the your track is playing back too fast thus sounding like chipmunk (ususally what people mean when they say chipmunk)? if so this is usually a sample rate problem and you may have changed a setting by accident. make sure that your sample rate are the same

I suppose “chipmunking” was the wrong term to use…its hard to describe, more like a "watery kind of sound with greatly reduced volume which is why i posted a link to audio of the problem. if ya could give a listen, that would be cool. BTW, i have Win XP and Audacity 1.2.6.
Thanks again…

My guess - you are recording with a laptop computers on-board sound card and it has some “noise removal” or “Automatic Gain Control” (AGC) effect that it is applying to your recording. If I’m correct, you will need to find the settings for your sound card where you can turn these effects off. There may be an icon near the clock that will give you access to the controls.

Thanks! that was it! problem solved! Thank you very much…

For the benefit of others, could you say what your sound card is, what settings you changed, and where you found them?

Realtek AC97 intergrated…i had something on my start menu called Multi-Channel sound manager, opened that up, clicked on microphone effect, then UNCLICKED noise supression, then clicked OK, and it corrected the problem.

On some inbuilt devices, another analogous and unwanted result of having the “noise suppression” recording option enabled is to filter out the higher frequencies - that may even be happening here. Although you might record at 44100 Hz (which should give you frequencies up to circa 20000 Hz in the recording, because a given sample rate can only carry frequencies up to half that rate), the actual recording only has frequencies up to circa 10000 Hz. This is easily confirmed by selecting a few seconds of the recording in Audacity and clicking Analyze > Plot Spectrum.


Hi, The problem is Your recording or line input volume might be too high. If you have a mixer like I have a 4 channel sound mixer from Radio Shack & Plug your cable from your guitar into your mixer if you have a pickup in your guitar i’ve got a fender accoustic. I have a Deam Markley Pickup from the Guitar Center In new london. I do alot of Home recording for a Hobbie!!! I’ve been playing guitar 8 years now. doin country, johnny cash, real country. only. I Enjoy it ALOT!!!

hope this helps TOMMY
