################################################################################
The Spectrograph application performs Fast Fourier Transform
on audio input (from file or microphone) and
draws its spectrogram (in real time).

Dependencies:
OpenGL, Freeglut 3.0
PulseAudio, libav-tools
The application itself expects a binary stream of floats of audio samples
on standard input, therefore it is recommended to run the wrapper scripts
spectrograph-mic (for real-time input audio processing)
and spectrograph-file (for audio file processing).
Simple usage:
spectrograph-file --file file.mp3
spectrograph-mic
For more options run:
spectrograph -?
spectrograph-file -?
spectrograph-mic -?
The interface (including options and wrappers) will change in later versions.
See:
VERSION for current version of the application
