hmm, this is even trickier than I thought. the problem is 20 and 24-bit formats are actually 20 and 24 bits of data in a 32 bit sample. internally audio(4) uses "precision" as the exact sample size. so, we have to distinguish between "padded" and non-padded formats in audio(4) first. btw, 32-bit formats should already be supported, afaics. they aren't "padded". -- jake...@sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org
