Hey Ott, in reference to the encoding at 256 kbps, if you are on iTunes right click on track-get info-file and it shows it. Blumenkraft is a variety (194 kbps-209 kbps on SG&C), Fairchildren is 256 kbps across the board etc. I myself am wondering what it is exactly and if it makes a difference in quality
That's down to iTunes.
I upload everything to them as 16 bit 44.1kHz WAV files.
