First of all sorry, because this question will definately be quite dull.
When it comes to 'later stages' of audio post-production I generally have no idea of all these many terms and procedures. Internet searches just confuse me more and more, so I'm searching for a book which covers the topic structured.
Due to my inability, I will just throw in a few terms so you can conclude about which field I'm talking: upmixing/downmixing from different sources LCR/LtRt/5.1/etc. ; nearly everything with 'Dolby' in its name (encoders, decoders, processors, codecs...); sound formats (AC3, DTS...); print masters; DCP, bitstream, PCM, ...it could go on forever.
