You haven't included the part of your program where 'msg' is declared,
so it's hard to say exactly why the compiler is whining...
The problem with packet is that variables can only be declared at the
beginning of code blocks in C and Nesc. A code block is surrounded by
{ } braces, so declarations are usually put at the beginning of
the function.
In answer to your audio recording question, search this list for
audio, microphone, and similar key words. I sent some links, maybe
last month, that didn't seem to help much but could provide guidance.
