I have recently started ripping all of my CDs into iTunes using ALAC. I’m nearly finished and afterwards I may want to convert my whole library to another lossless format like FLAC, AIFF, or WAV using dBpoweramp. My question after reading this article: https://support.apple.com/en-us/HT204310 , is in the very beginning of the article they referred to ALAC as a compressed format, and towards the end of the article they state that converting from a compressed format to an uncompressed format (AIFF or WAV) there will be no difference in sound, but the file will take up more space. Does this only apply to converting within iTunes? I plan to do all my converting in dBpoweramp, but before I do it I’d like to know I’m not wasting my time. I plan to covert my library to FLAC, as well as AIFF and/or WAV too. What settings should I use for converting from ALAC to FLAC, and also ALAC to AIFF and/or WAV? In the end I want three separate libraries: ALAC made from importing CDs into iTunes, FLAC library made by converting ALAC to FLAC with dBpoweramp, and AIFF or WAV made by converting ALAC to AIFF or WAV using dBpoweramp. Any input will be greatly appreciated.
