I am trying to downsample some tracks to make a kind of comparation between sample rates, to verify to myself if I am able to hear any difference. To be sure I am using the same mix of the song, I tried to downsample the tracks using "Switch Sound File Converter", which works fine when changing formats (for example, flac to m4c), but creates clicks and distortion when downsampling. I try with different formats and codecs, and all the time the same.
Any advice on how to properly downsample the file?
Other question: is there any way to carry a blind test using JRiver?
