For most stuff you will find "Application Notes" from the manufacturer of the mcu.
After all, it is in their interest to make development with their as easy as possible, so they will work on and release app notes.
Well, I haven't worked with audio streams so far, so I just google "adc audio app note".
for my mcu that might be:

I'm sure there is something too about using DSPs and DACs. But the actual algorithm for the DSP is up to you and your needs.
Almost all mcu's are programmed in C, but you can use assembler if you really want too.
For the configuration and initialization there are free tools from most manufacturers, which help you with creating projects for your ide with all the necessary stubs.
Like pic related: pick mcu, configure pins, do some settings, create project.
