Hi there,

I was reading about pyramid vector quantisation and it was mentioned 
that Opus uses this type of encoding.

I understand that Opus has many different steps in the encoding process, 
it is rather formidable !

Are the encoding methods used in Opus based on polar or spherical 
components ?
Does opus encode polar movements ?
