If you pair headphones that don't support AAC to an iPhone, it will transmit audio using SBC.
So the way it works is it takes the source audio, transcodes it to the codec for bluetooth, transfers the sound to the headphones, the headphones decode the codec in a DAC and send analog audio to your ears. Apple does not want to pay Qualcomm to license AptX, so they use AAC. Many codecs require certain license agreements. Not all headphones are compatible with all codecs. AAC is favored by Apple because it is their home-grown one. There aren't that many bluetooth audio profiles that are high quality. Amazon is also very good but I just hate the way it handles albums (adds an album for every track on a playlist so I ended up with hundreds of 1 or 2 track albums)ĭon't forget on an iPhone if you listen wirelessly you are capped at 256 kbps anyway as AAC bluetooth does not support any higher I think that others such as Deezer or google are with considering as they get strong reviews for audio quality. I am not a massive fan of apple music either but the consistency is excellent.
#Apple music vs spotify 320 kbps#
I read somewhere that not all of the library is actually 320 kbps, apparently back in circa 2010 they were supposed to convert all of the library to 320 kbps ogg format but some feel that they did not do this or just upscaled rather than replaced, or maybe their source files are not great to start with? I love the discovery and it is the best app imo but I am only keeping it as it is free for me until June. I have both and just find spotify to be inconsistent, when it is good it is as good as apple music imo but there are just too many turds in there.
