I just got done dumping 2 shows onto my laptop. I opened all the files in audacity to normalize then exported them to there proper place. before putting the sd card back in the recorder [ sucks leaving the sd card at home in the lappy!!!] and formatting it, I actually got some time to check them out. they both have light crackling, like a bad connection or even a type of interference. its not constant through ether of the shows, but deff the same sound in each. no real pattern. so I went to the SD card to check the original files to see if they matched up with my files I used audacity on before setting up my gear to try and reproduce noise. not a peep on the original files. weird or did I do or not do something that was needed. I don't use audacity much, but its cut and dry on using it. any help or input is appreciated . thax, ed
