hi,<br><br>I have a project at my university to look through the vorbis encoder and run some tests on how it is working in different situations etc. therefore I have some questions that you probably know the asnwers for. Please, help - I want to understand correctly the the process:
<br>a) the floor vectors are the less precise vectors representing a spectrum in a channel<br>b) they are selected from the predefined ones in modes/setupXX.h<br>c) are they somehow computed with the use of data provided in the stream of pcm samples?
<br>d) this information is sent once in a header no.3<br>e) the residues are the differences between floor vector and the actual spectrum<br>f) in which file/function that process is shown<br>g) in the header packet is sent a type of residues (0,1,2) ? because i understand that
<br>h) the residues are in fact in audio packets because they represent the actual values<br>i) code books are somehow computed to minimalized the space for codes of residues?<br>j) where is that?<br>k) which file is responsible for coding the audio packets?
<br>l) which file is responsible for packing data into packets?<br><br>thank you in advance, Mike.<br><br clear="all">
