There is no "DSP" going on in any of the examples - at least not in the sense you mean. The volume-based functions are all extremely lightweight. RG for example simply adds/subtracts a fixed value from each sample. Likewise the volume control. Crossfade subtracts a slowly increasing amount. Although these are technically "DSP" functions they aren't the sort of thing you typically use SOX for. -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...
