Can someone explain the purpose of upsampling?
Have a music streamer/server that has HQPlayer embedded and I’ve tried upsampling MP3 and flac files to DSD64 and DSD128 but don’t notice any difference. Know upsampling is also available in Roon.
Seems like trying to get more resolution than exists in the source file. Like converting a mp3 file to flac.
What am I missing?
