VAD algorithm implemented using ALSA library in C programming language

Voice Activity Detection (VAD) algorithm made based on Moattar and Homayounpour's publication A simple but efficient real-time voice activity detection algorithm.

Code is written in C language using:

• ALSA (for sound processing)
• pthreads (for multithreading)
