Installation of FAAD2

Install FAAD2 by running the following commands: 

./configure --prefix=/usr --disable-static &&
make

This package does not come with a test suite. However, basic functionality can be tested by decoding the sample AAC file: 

./frontend/faad -o sample.wav ../sample.aac

This should display a copyright message and the following information about the sample file:

sample.aac file info:
ADTS, 4.608 sec, 13 kbps, 16000 Hz

  ---------------------
 | Config:  2 Ch       |
  ---------------------
 | Ch |    Position    |
  ---------------------
 | 00 | Left front     |
 | 01 | Right front    |
  ---------------------

Now play the result (requires the aplay program from the alsa-utils-1.2.1 package): 

aplay sample.wav

aplay should identify the file as “Signed 16 bit Little Endian, Rate 16000 Hz, Stereo”, and you should hear some piano notes.

Now, as the root user: 

make install
