Getting rid of fisssss fissss ....

Post by hadiuk » Sun Aug 29, 2010 5:52 am

Hello to everyone...
I have read all the instructions and wiki etc... tried all different settings etc... but the problem is still there

I am not very technical so the strange topic title... so please stay with me.
although i am not so technical but am a good friend of Audacity for years.... here is my problem:
to help you understand my problem, i have made an photoshop illustration you can see it here:

when i record a song from my computer, then export it as MP3, in those areas marked RED as "B(PROBLEM)", I get a horrible fissssssss fisssssss sound over the song itself, and they are where the singer sings or song goes high pitch... otherwise, when the song or singer are in low pitch and steady, i get the area marked RED as "A(ok)"...

how can i get the song recorded like in A(OK) area, all the way? i think i have some settings wrong.

i have the same problem in 1.2.6 version.
as long as i was using Windows XP, It was ok and no problem.

here is a sample of an exported MP3 file with that problem:

I am using both 1.2.6 and 1.3 version of Audacity, Windows 7 and i have done all the settings described in wiki.(i also have put my laptop's sound cart IDT high definition audio codec as a Default device)
Can anybody help with a simple language?

Thank you very much in advance for your help.

None of that recording is ok - you have clipping throughout the sample you have posted the pictures of (that's why you get the horrible noise.

It's because your input signal leve is far too high - you need to reduce the level either by using Audacity's input signal control (the slider with the microphone icon) - but note that if you are using a USB device then this may not be operable) - or by using the hardware gain/volume control on the device you are recording from.

You're recording too loud. When you record the performance, the red bouncing light sound meter should not go all the way up -- to the right. The blue waves should not touch "1" in either direction.

A recording that is too loud or overloaded can not be recovered. It is permanently damaged.

We don't know how you're performing the recording, so it's difficult to tell you how to fix it. Is this a live microphone? How is it connected to the computer?
