Pandora uses AAC (Apple's advanced audio codec) for 64 kbit/s, not MP3, which would sound far, FAR worse. Are there any plans to switch to HE-AAC v2 or OPUS for these lower bitrates? I don't think OPUS will sound any better than AAC, as I have encoded some songs at 64 bit opus, and it's only medium, half-decent quality. AAC at 64 kbit/s is quite similar, but OPUS is open-source and newer. HE-AACv2 has the edge in very low rates less than 48, compared to opus, but above that, opus seems to sound a bit better. Are there any plans to switch the audio codecs used?
