SoX Wrap is a wrapper of the conversion routines of the
open-source sound utility SoX. It handles conversions between many different formats: 8svx, aiff, al, au, avr, cdr, cvs, dat, gsm, hcom, la, lu, maud, mp3, nul, ogg, prc, raw, sb, sf, sl, sph, smp, snd, sndt, sw, txw, ub, ul, uw, vms, voc, wav, and wve. It is a batch converter: you can give it a long list of files to churn through, and walk away.
Addition (1/5/09): The Xcode project for this is now available at
