We used to have earbuds that don't need to be charged because they had a headphone jack, didn't get lost so easily because they had a cord attached to a headphone jack, never lost the bluetooth connection because they had a headphone jack, and they cost less because they had a headphone jack. https://bsky.app/profile/daisyfm.bsky.social/post/3l3mfjc6sn62k
It’s a bit more complicated than that. There are multiple codecs available (some with much higher bitrates), but even in AAC (which I assume you are referring to) there are different implementations. Also note that 328kbps is not “garbage mp3”, 128kbps CBR was the common (and shit) variant that you probably meant. But more modern codecs achieve much better fidelity at lower bitrates even.
328kbps is absolutely horrid and nowhere close to CD quality (1411 kbps). Good quality audio is over 6000 kbps.
328kbps in a lossy format is plenty. You might be one of those people who claim to hear the difference, but to date we are yet to see a double blind trial where a substantial percentage of individuals reliably could demonstrate such ability.
328 kbps is nowhere near enough. 1411 kbps .wav is the minimum I'll listen to, even on my phone.
24 bit 96kHz is optimal, but I can't hear any difference going higher than that.
