Tools for simple software analysis of microphone audio for Windows?

Question

Perl

Hello.
Maybe someone knows the tools (programs with APIs/libraries for Perl, C++) that will help to analyze the audio signal coming from the microphone in real time.
Task: In real time, "listen" to the Audio Input on the computer, and analyze the signal level. If the signal becomes too weak, call a trigger.
Available programming languages: Perl, C++ (but Perl is better)
Thanks in advance

Answer 1

For C++, convenient for building applications: WDL-OL , Juice , Cinder .

Answer 2

At the moment, I found a cross-platform portaudio solution and a module for it for perl Audio::PortAudio
But at the moment I encountered difficulties in installing this module. And apparently not only me: judging by the information from the CPAN page, only 1 test out of 3 was passed.
I try further.
