History of Voiceprint Identification

About VoiceApp

VoiceApp works by reading audio directly from your soundcard (in Linux it's file /dev/dsp), and transforming data via FFT. The result is thrown on the screen in matrixish colors ;).

Version 0.4.2 in action here(220k).

Requirements

Pentium (??) -- developed on PPro200/GF2PCI and eats 10%..
SDL (Simple DirectMedia Layer) -- www.libsdl.org.
FFTW (Fastest Fourier Transform in The West) -- www.fftw.org.
Linux (www.linux.com) -- VoiceApp sets some linux (OSS/Free??) specific settings, so porting it onto other platform is not easy. (as a side note, I have somewhere sources for same-kind app using DirectSound & MS Windows things..).
To get them under
debian/unstable (don't know about stable):
apt-get install fftw-dev (needed to compile)
apt-get install sdl1.2-dev (-''-)
then
make and ./voiceapp.

NOTE!
Please verify that your Microphone / line-in is not 'muted'.
VoiceApp needs some data input to work..
