Note:
Encodes with quality presets, not constant/variable/target bitrates
Floating point samples makes Vorbis very flexible, it's 32-bit floats though
Fairly popular audiobook format
Commonly paired with Therora video format
Created because of a licensing dispute with MP3
FSF approved
Standard is public domain
Apple are weird and don't support it
