Audacity Forum

Hi, as I don't know the name of the problem, I took a look at the forum, but it is hard to read everything that might be some help. Sorry if you people answer the same thing every day!

I'm recording from a CASIO Privia PX - 310 to a laptop computer, windows XP using audacity 1.3 beta... I saw many people asking about free space of the computer, so mine is about 35% in use only.
The problem here is that when I record long notes or short notes using the damper pedal of the piano (specially if they are many repeated notes), the sound recording starts fine but goes fading out as if it was under water or something like that. I can't describe, so there is a sample with pipe organ. It also happens with drums, guitar, bass sound... even with the piano sound, in faster songs, specially in low notes - by low notes I mean the ones on the left part of the keyboard. If it's of any need, I am recording with 1/3 of the max volume of the piano.

Åh, I'm using a Y cabe with two RCA jacks (with converters to make them big mono jacks) and a stereo small 3.5mm jack in the other side, connected to the micropohone plug of the laptop.

I appreciate any help!

Microphone inputs on laptops frequently have "Noise Suppression", "Echo Cancellation" and other such effects. You need to find all of these effects (which are usually hidden in the sound cards control panel and can be hard to find) and turn them off.

Ok, I inderstand not much on computers, but I'll try to find these stuff. Thank you very much!

As I'm already here... Any tips on how to desable or how to control "noise suppression" and "echo cancellation"?
And I have no PC at home, but if I try recording it on a PC it will not happen, is that right?

Unfortunately the place to disable this varies from one machine to another. Here's the setting (left side - green dot shows it is enabled) of where it is on one version of the RealTek sound card control panel. To access the sound card control panel, you can often open it by double clicking on a loudspeaker icon near to the Time/Date on the desktop.

Hahaha Thank you so much! You saved me!
It works now, thank you really much!
