New and Improved AST Conversion Software by ArcticJaguar725 at 3:28 AM EDT on August 17, 2017
Yeah, yeah, I'm aware that software already exists for the creation of Nintendo AST files, but I've found all of them to be unsatisfactory. For one, some of them just crash on me when I try to use them, but there's one thing that every program I've seen has in common: that is, they require the entry of loop points using milliseconds! Being a perfectionist and an audiophile, that is just not specific enough information to be able to create a satisfactory AST file.
So I decided to write my own command line tool, which can be found here. In addition to accepting loop points using samples, it supports creation of multichannel streams and allows the disabling of looping, among other things.
