I’d like to see the option to upsample certain formats. Yes, i know, there are a few options already, but what i’m after is to upsample my low resolution files primarily, such as 320kbps MP3’s and AAC. At the same time i’d like to leave lossless content “as is”.
To my ears, lossy files benefit mostly from upsampling, but they are frowned upon by most of us here.
And quite correctly so, as most of them could be replaced by their streaming service equivalents, but there are quite often gaps in Tidal and Qobuz’s catalogues.
