Buffer and CoreAudio ?

Hello,

i am totally new to Audio.
I am seeking to find the best way to make a very simple application :
- I need to record audio then to have that sound as buffer
- I need to get that buffer and send it to another function i made with parameters.

Format :
- WAVE
- 8000 Khz
- 16 bits

My questions are:
#1 what is best to use CoreAudio or Quicktime ?
#2 Why is it so hard to get AudioStreamBasicDescription gAACFormat = {8000, kAudioFormatLinearPCM, kLinearPCMFormatFlagIsPacked | kLinearPCMFormatFlagIsSignedInteger, 2, 1, 2, 1, 16, 0}; informations relative to format options. Exemple, if i change number of channels size i get a fail in the file creation.
#3 i need to Set buffer ize but without success (i based my first try on CoreAudio sample source on Apple website)

Maybe these questions were already treated but i cannot find explicit answers.

thanks for your help
