man bash will answer some of these questions.

$ is for variables.
$f is for the variable "f".
% can be used to remove text at the end of a variable.
{} these braces wrap the expansion you want bash to do, but are optional
in simple cases.

Here is where you probably want: ${f%.C.aif}

This means: expand the variable "f" and remove ".C.aif" from the end.
