Thank you for your good work!

It would be very nice if mpd-dsd could support the new branch of sox with PCM --> DSD upsampling (patching Sox Resampler.cxx)

A package sox-dsd-git is already available for archlinux at https://aur.archlinux.org/packages/sox-dsd-git/ I have also made yesterday a package for mpd-dsd 019 with your patch here https://aur.archlinux.org/packages/mpd-dsd/

Nice! Good to have a way to do DSD upsampling on Linux. I did a few testruns outputting DSD64 and DSD128, it takes quite a while to convert a FLAC file to DSD. Realtime conversion does not seem to be possible with the current sox SDM code.

According to the developer the option "fast" is "Reasonably good quality while fast enough for real-time operation. This is the default." Example: sox PCM44.flac DSD64.dsf rate -v 2822400 sdm -f fast

Available options (from fast to very slow) fast hq audiophile goldenear
