It is my understanding that an updated 24 bit 'reference' (funny that the reference library for ALAC that everyone uses does not come from Apple...) codec will appear on crazy.net in the near future.

Thanks for the update. I have downloaded and installed the new pack. I have a ~2000kbps ALAC file that is 24-bit at 44.1KHz. I made it from a 24-bit 44.1KHz WAV file downloaded from a website. The ALAC file was made with iTunes a year or two ago but I could never use dBpoweramp to convert it. I would always have to use iTunes to convert it to WAV first and then use dBpoweramp to convert that file.

I effectively converted that 24-bit ALAC file down to -q0.45 with Nero AAC without issues. I even converted it to a 24-bit FLAC file without problems. Thanks for updating your ALAC encoder/decoder. I don't have any other 24-bit files or I would test ALAC encoding.
