I’ve been playing around with the headroom setting and upsampling (with great results), but one thing seems like it could help a lot, especially with dialing in how much headroom you really need to add, and that is to add logging of clips in the RoonServer log of you’ve enabled the show clips option in the headroom settings. That way, you don’t have to sit there and look for it go red - you can play tons of music and then look back in time if anything clipped. It would also be nice to have track name and track timestamp if possible just incase you want to listen to that specific area when you go to tweak the DSP.
Thanks!
