      It's extremely sad that it's 2020 and internet streaming and Twitter video are stuck with 90s era 96kbps mp3 quality audio, **because of bad code**, and apparently nobody cares.

      OBS doesn't let you pick a codec for streaming, but it *does* let you configure a "recording" output that actually goes to an RTMP stream, and *that* lets you pick codecs, so you can pick MP3 and get way better audio quality than with the ffmpeg AAC encoder (at a lower bitrate).

      Honestly it's kind of funny how the open source world has best-in-class h.264 encoding (x264) and worst-in-class AAC encoding (ffmpeg aac) and those two are most often used together.

      Anything that performs worse than MP3 is tied for last place.

      VO is, to be clear, _much_ worse

      Is Google really using that in Android?

      they used to! now they use FDK (which is why it's open-source-ish to begin with)

      So on the sample I'm testing now libfdk_aac actually does worse than LAME. Though to be fair, the original file was already an MP3, so that probably gives LAME a bit of an advantage.

      qaac (QuickTime/AudioToolbox) is usually considered best-in-class fwiw

      Scratch the previous reply; libfdk_aac falls over with overshoots (makes sense, it's integer) and I was feeding it some fairly clipped mix. After lowering levels it's better than LAME.
