Category: None Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Jesus R (sonorejr) Assigned to: Nobody/Anonymous (nobody) Summary: dsd to pcm support Initial Comment: Sebastian Gesemann wrote a c based code to convert dsd (dsdiff) to pcm at 24/352.4. I contacted Sebastian and request to be able to use and distribute the code he said sure. I can provide the exchange between us as needed. I then had a friend modify the code to parse the dsd data and make the same conversion without the header information. Can we add dsd to pcm support directly to SoX with this code? I can provide the code as needed.

I don't think we need it: sox's existing downsampler should be sufficient and may even be more efficient as it's FFT-based. > The most used fileformats which contain DSD streams are DSDIFF... Yes, so this is the main work that's needed, to write a reader for the container files. I'm not sure that it warrants the effort though (DSD seems something of a failed experiment), but if someone wants to submit a patch for it, I'm sure it could be added. ---------------------------------------------------------------------- Comment By: terual (terual) Date: 2012-10-10 02:15 Message: Sebastian Gesemann release his DSD2PCM code under the simplified DSB license here: https://code.google.com/p/dsd2pcm/ The license probably simplifies using his code. The first stage of his code converts the raw DSD stream to 352.8 kHz PCM 32-bits floating-point and this is probably the only part which should be used. The most used fileformats which contain DSD streams are DSDIFF (see http://www.sonicstudio.com/pdf/dsd/DSDIFF_1.5_Spec.pdf) which has the .dff extension from Philips and the simpler DSF fileformat from Sony (see http://www.dsd-format.sony.net/data/DSFFileFormatSpec_E.zip) which has a .dsf extension. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=360706&aid=3438368&group_id=10706 ------------------------------------------------------------------------------ Don't let slow site performance ruin your business.
