At least my application. And I'd be happy to support any custom format created for the purpose... :) (http://www.signalyst.com/consumer.html for those who are interested) I would propose to create custom 8-bit sample formats for DSD purposes, similar to the ASIO formats. Practically two main ones, byte with oldest bit in MSB and byte with oldest bit in LSB. And maybe the "DSD-wide" one which is 8-bit DSD sample. - Jussi
