Quoted from digitalbytes:Does anyone else have a problem with clipping? I process songs and they sound terrible once they are on the pin with popping, cracking and distortion (Whisky in the Jar in particular). I am converting from .m4a (iTunes) files to .wav using Audacity and I am wondering if it's Audacity that's causing the problem because the songs sound fine as .m4a's.
I am no expert and am still learning myself but are you changing the Project Rate to 24000Hz in the bottom left corner in Audacity?
Sorry I couldn't be more help?
