32 <para><application>FAAC</application> is an encoder for a lossy sound
33 compression scheme specified in MPEG-2 Part 7 and MPEG-4 Part 3 standards
34 and known as Advanced Audio Coding (AAC). This encoder is useful for
35 producing files that can be played back on iPod. Moreover, iPod does not
36 understand other sound compression schemes in video files.</para>

76 <para>This package does not come with a test suite. However, basic
77 functionality can be tested by encoding a sample WAV file (the sample
78 file is installed by the <xref linkend="alsa-utils"/> package:</para>
79
80<screen><userinput>./frontend/faac -o Front_Left.mp4 /usr/share/sounds/alsa/Front_Left.wav</userinput></screen>
81
82 <para>Then, decode the result using the <command>faad</command> program
83 from the <xref linkend="faad2"/> package and play back the decoded file
84 (requires the <command>aplay</command> program from the
85 <xref linkend="alsa-utils"/> package:</para>
86
87<screen><userinput>faad Front_Left.mp4

123 <para>The quality of <application>FAAC</application> is not up
124 to par with the best AAC encoders currently available. Also, it only
125 supports AAC and not High Efficiency AAC (also known as aacPlus), which
126 provides better quality at low bitrates by means of using the
127 <quote>spectral band replication</quote> technology. There are the
128 following alternative programs for producing AAC and HE-AAC streams:</para>

138 Enhanced aacPlus general audio codec</ulink>:
139 available in the source form, can encode only HE-AAC up to 48 kbps
140 out of the box, but the maximum bitrate can be changed by editing
141 the tuning table in the

146 <para>Note, however, that iPod supports only Low Complexity AAC profile,
147 which is the default in FAAC, but may not be the default in Nero AAC Encoder
148 and is completely unavailable in the 3GPP encoder.</para>
