[QUOTE="dcs.79c, post: 1951247, member: 333068"] Wow! 4000+ CDs! These comments/questions apply to Apple Music (henceforth AM). I noticed that FLAC doesn't appear in AM, but ALAC does! As does WAV. I noticed that the AAC on AM encoder maxes out at 320 kbps just like mp3. Also, the AAC sample rate is fixed at 44.1 just like a CD. What's High Efficiency encoding on AAC? Is that VBR? The sample rate on AIFF maxes out at 48 kHz. That's higher than the CD rate. No custom settings on ALAC. For mp3, the higher the "Quality", the bigger the file. I thought that the sample rate for mp3 was fixed. Apparently not. It can go as high as 48 kHz. What is joint stereo? I've seen that on YouTube. What are smart encoding adjustments on mp3? [/QUOTE]
