Yeah, but sox did not produced ten times better sound, so i feel this much resource need a bit too much.
The archives are separate, because this tool should be in C: and the executable names are identical. I could put them in drawers by CPU, but why? The three archives together weighs around 32k, i think that's small enough.
As for the readme, what should i write into it? The program prints the usage when no parameters passed, no further info needed to use.
If you think, there is a need for an aminet release, then you can make an aminet archive the way you want: you can put the three version into the same archive and you can include a readme too; the tool is free to put to any website.
