How to get audio input volume

[lveillette <lveillette at jourdelaterre dot net>]

Hello,

I would like to know how to obtain the audio input level.

I am looking for something that I could poll to get the general level, and
if possible to get a level at specific frequency or over a range of
frequency.

Does someone have some code examples?

Thanx


Louis Veillette
