Hi Chris. Can you give us more infos about this "open source" object-based platform? Because sometimes, "open source" can mean "mostly closed".
Also, PCM (or LCPM) is a lossless format; how can DSD sound better at the same resolution? Are you referring to the format or the hardware? -- Marc On Thu, 21 Apr 2016 18:26:17 +0000 (UTC) chris boozer <chrisboo...@yahoo.com> wrote: > DTS-X is based upon an open object codec that SRS labs developed and > open sourced, the decoder is a proprietary implementation but > anyone can make their own decoder.
