Audio Capture Static

FredJones · 10-20-2009, 10:41 AM

I use ArchLinux with Xfce. I am using XVidCap to try to make a screencast but the audio quality is not good. The problem is background static. I think the mic is pretty good and it had good quality on another machine.

I tried another mic and it also has a hiss. The files are here:

and

If I play with the sound level of the pink mic input it seems to change, but nothing sounds good.

Are there other settings I should try to change?

Thanks!

Hi FredJ

check the mixer settings to see if the mic input is enabled and not muted.

Also check alsamixer and make sure to uncheck any mic booster, I've found this always amplifies background noise.

Then there's also the option of running a denoise filter on the file, say using audacity or other program.
