future: Research more about Opus as standard audio codec

[geolffreym]

Based on quality produced from high to low:
libopus > libvorbis >= libfdk_aac > libmp3lame >= eac3/ac3 > aac > libtwolame > vorbis > mp2 > wmav2/wmav1

"Our target will probably be CELT algorithm capabilities " for audio low latency
https://en.wikipedia.org/wiki/Opus_(audio_format)
https://trac.ffmpeg.org/wiki/Encode/HighQualityAudio

Why is this?

• Biggest bps support - full band stereo
• Opus has very low algorithmic delay a necessity for use as part of a low-audio-latency
