There is a song called "The World Spins" by Julee Cruise which was played on Twin peaks, and I notice the version on the show is different from the one on the album -- the version on the album sounds slightly flatter and more artificial. Is there any way to discern why this might be the case by listening to the music? Is it because the version on the show was recorded live in studio as opposed to recorded using tracks? Is the TV version less compressed? I was hoping someone more knowledgeable than me about music production might be able to listen and come up with an answer.

i am aware of aptx, but to me it still just proves how shitty today’s standars are. we already have opus. if aptx is better than opus then i want to encode my audio to aptx and listen to in even on my phone with wired headphones AND bluetooth devices WHITHOUT trancoding. if opus is better than it should be supported in a2dp. afaik opus was created especially with low latency streaming in mind. bringing in aptx which is also heavily patented (i suppose) is pointless from technical point of view and is just a way of making money by qualcomm
AFAIK the only codec used both for music and BT A2DP in any significant way is AAC. Usually speakers and headphone manufacturers will advertise it if they use a non-SBC codec, it's selling point. Most modern Sony speakers and headphones use AAC at the very least, with higher tier ones using also LDAC. I know MP3 also can be used for BT, but no one that I know uses it, especially not any mainstream devices. In contrast, AAC over A2DP is supported in AOSP since Android 8.0, so probably all devices with 8.0 and above will support it. I think Apple also supports AAC on Bluetooth. Now if the devices will or won't reencode the AAC stream is up in the air, who knows.
