When I was younger I would listen to music recorded on my phone from the radio. They were 128 kb/s, which sounds OK until you see they’re .wav files so they don’t use the bitrate effectively: just mono, 32kHz sample rate, 4 bits per sample. They sound worse than 24 kb/s MP3s!
(The SoC can and does do AMR compression when recording MPEG-4 (more specifically 3GP4, which uses MPEG-4 part 2, not the well-known AVC, which is MPEG-4 part 10) video but the manufacturer just didn’t take advantage of it, maybe the library for video recording was proprietary and the AMR codec not well documented.)
Audiophiles when they can’t tell the difference between lossless and 320kbps mp3:
That’s my coworkers face when I said I find mp3 rips sound muddy to me, so I have been using flac and wav.
I had to prove it to him with two back to back rips.
But for many people, like my darling wife, she can’t discern the difference and a clippy phone speaker is the same for her as my DAC on a 5.1 system
me listening to music I encoded at ~90 kbps opus
