Hi I know how to remove noise, but I want to find the solution to prevent it while record. Thank you. ----- Original Message ----- From: Jacob Kruger To: audacity4blind@xxxxxxxxxxxxx Sent: Monday, December 29, 2014 12:46 AM Subject: [audacity4blind] Re: ask about recording Not sure what's causing it, but, if you can find a piece of recording that just has noise in it, select something like a second or two of that piece, and under effects, look for noise reduction, and use the initially focused button to sort of evaluate/match what counts as noise, then select whole track, bring up noise reduction again, and apply it - haven't used it for a little while, but, for example, it took out background noise from LP recordings for me.

Now I see a problem, that the recorded file sometimes has noise like we turn on the fan while recording. I turned off my microphone, and record. It still have a noise sound. Are there anything i need to check? Using a desktop with windows 8 professional 64 bit, latest audacity, and the audio Technica ATR 2100 microphone. The mic plugged directly into the USB port.
