SoX resampling setting options
#1
I play audio files in FLAC format as a priority. What are the recommendations for MPD (Sox resampling) settings? Thanks for the tutorials and comments. I am currently using the 24bit / 192kHz setting. It is correct ?

I don't think there is a universal consensus. I for one prefer to leave resampling off and feed the DAC bit-perfect stream. I have read people that are resampling to as high as what the DAC can handle or the DACs internal upsampling rate to ease its load.

Then there is the quality settings. I have read reports of normal and high values working best, while others prefer the high quality settings.

What does you hearing tests tell you? Which do you prefer?

Exactly as @RafaPolit said.
It all depends on what DAC you using and what your ears tels you.
And also keep in mind that upsampling is put an extra demand on the CPU and every extra computerized process have some errors which need corrections. So this may actually lover the audible quality of the output sound you hear.

So the best is you try and set which ever you prefer

I fully agree! One test you can run is using SoX to upsample via command line to create a new file that matches the rate that you have set MPD/SoX to use. I believe the playback from the external upsampling is ever so slightly better, not enough to make me batch-create a whole new library that will possibly go out of date when I next change  DACs. The drop in CPU usage is not small.
