Confused by the different versions of AAC (LC, HE, HE v2, SSR, etc.); LC vs HE 2019-10-18 17:04:58 Hi all -- I'm confused by all the different versions of AAC and was hoping you could clear some things up for me. I've read the Wiki, which was helpful, but I still have some questions.First, am I correct in understanding that Apple uses AAC LC with iTunes tracks? Does this apply to songs purchased from the iTunes Store, or songs ripped using the iTunes app as the encoder, or both?Why would Apple use the Low Complexity format? Wouldn't that translate into lesser audio quality than regular AAC?Which yields more transparent audio at the same bitrate -- HE or LC?Thanks for your help.
