What is Aquila?
===============

Aquila is a digital signal processing library written in C++.

NOTE: Aquila 3 is an experimental release breaking backwards compatibility.
We're moving from Subversion to Git, from qmake to CMake, reorganizing 
core classes and introducing major API changes. The work is still under
heavy development and at some commits the source code may even not compile. 
Remember, you were warned :)

See http://code.google.com/p/aquila for the stable 2.5 branch.


Features
========

This is copied from Aquila 2.5 description.

 * reading input files in WAVE format, 8 or 16-bit per sample, mono or stereo,
   with almost any sample frequency
 * dividing input signals into short frames and applying mathematical
   transformations to each frame
 * calculating energy, power, FFT and DCT of a signal
 * feature extraction, including MFCC and HFCC features, widely used in
   speech recognition
 * a simple DTW (dynamic time warping) pattern matching algorithm which
   also can be used for recognition


Requirements
============

The following dependencies are required to build the library from source.

 * Boost C++ libraries
 * CMake > 2.6
