Introduction to FAAD2

FAAD2 is a decoder for a lossy sound compression scheme specified in MPEG-2 Part 7 and MPEG-4 Part 3 standards and known as Advanced Audio Coding (AAC).



Development versions of BLFS may not build or run some packages properly if dependencies have been updated since the most recent stable versions of the book.

Installation of FAAD2

Install FAAD2 by running the following commands:

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

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-1.2.6 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
