OK, I think I found my answer, this one should be right:
gst-launch-1.0 --gst-debug=audio-*:5, filesrc
location="/var/lib/mpd/music/NAS/loss4/Nina Simone/Baltimore/1.
Baltimore.flac" ! decodebin ! audioconvert dithering=tpdf-hf
noise-shaping=simple ! audioresample quality=10
resample-method=blackman-nuttall sinc-filter-interpolation=cubic
sinc-filter-mode=interpolated ! audio/x-raw, rate=176400 ! alsasink
device=hw:1,0
the only thing is that I don't understand how to activate dither, from
the log it seems that it doesn't apply it:
