I want to buy Switch, but it isn't working. I've put .aif files in, and I want to convert them to a different sample rate (but keep them .aif). I choose the correct options, hit convert, and the file Switch creates always has the same sample rate as the original. Switch acts like it's working, when really it's not. I've been very happy with switch for making quick mp3s and such, but this is frustrating. Any answers?
