Pop at end of samples in 60

Anyone know of a software that can convert those .snd files into wav?
I have Chicken Translator, and it does that, but while the previewing works well, the result of the conversion is always closer to a burst of noise than actual sample.

not sure if awave (i think it was called) did the 60 SND files... there was a few pieces of software on windows that apparently could do it. What I always did was, i loaded the SND files from the 60 disk into the 2000 classic and it read them fine.. then resaved them on a 1.44mb floppy disk, but i can't remember if you were able to resave SND to .WAV.

Thanks guys!
I'm on a Mac though.

However, I reported the issue to Chicken Systems, and they just fixed the file conversion!
