I am pretty new to this game (elec. music), wondering what others on Mac use to slice and dice audio files and extract samples for use in AudioMulch and elsewhere. I have a program called Fission, from Rogue Amoeba, which I can recommend for general trimming and manipulation of files, but to zoom in very close, I need to first chop out a rough piece of file, then reload that piece and trim again. So, I am looking for something with more precision. Are there any programs known to be especially good for this kind of thing? Thanks in advance.
