there has been a discussion about the sound quality that in 3/2010, unfortunately split up in a few threads: http://lists.puredata.info/pipermail/pd-list/2010-03/077079.html http://lists.puredata.info/pipermail/pd-list/2010-03/077205.html (…) the upcoming double precision Pd will change a few things there i recon.
