Shairport-sync and SOX upsamling - howabout - 03-30-2022

Hi,

I am listening a lot to Apple music using the Airplay Renderer in combination with CamillaDSP using a RPI 4. In the airplay configuration panel in moode I've chosen SOX for upsampling the files (Not Basic). However, in the MPD config window I have not enabled SOX resampling. Is shairplay using a separate SOX installation/library? Or can I modify the SOX resamping settings from the mpd configuration page? (even if it says it is not enabled)

I would like to change my filters as described here at archimagos website:

It seems to me that it should be possible to replicate these settings using the "custom" resample settings.

Thank you!

It's using SoX but its completely separate from MPD's use of SoX.

Thank you so much for your swift reply!

I was suspecting this. Are you aware of some way of adjusting the digital filters using a configuration file, or accessing SOX via some other interface, or do I need to fix this in code and recompile?
