I wrote a script that upsamples 16/44 MP3s to 24bit 48khz MP3s. These MP3s work in my car (24/96 JVC KD-SH99) and on my PC (24/96 Echo MIA soundcard.)
The script is quite elegant, I can convert a few hundred MP3s overnight.
Probably doesn't sound as good as a kilobuck audiophile upsampler, but I do hear a slight improvement in the treble on the 24/48 mp3s.
How does your script upsample 16/44 MP3s to 24/48?
MP3 files have a fixed sample rate and can be decoded to any precision.
