1. Fftrate is a set of libraries, programs and plugins designed to change sound parameters:
  - bit depth
  - number of channels
  - sampling rate (this is the most important thing!)

3. Project build.

3.1 Essential Libraries and Tools.
For build, it is enough to have a gcc/g++ compiler with a standard library.
However, for the ALSA plugin, you must install the ALSA development package (in the case of Debian: libasound2-dev).

3.2 Build order.
Build all:
    make

Libraries only:
    make libs

Console programs:
    make libs apps

ALSA tools:
    make libs tools
