NAME
       faad -- Process an Advanced Audio Codec stream


SYNOPSIS
       faad  [options]  [-w  |  -o  <output_filename>  | -a <output_filename>]
       input_filename


DESCRIPTION
       This utility provides a command line interface to libfaad2.  This  pro-
       gram  reads  in MPEG-4 AAC files, processes, and outputs them in either
       Microsoft WAV, MPEG-4 AAC ADTS, or standard PCM formats.


OPTIONS
       -a &lt;filename&gt;, --adtsout &lt;filename&gt;
              Sets the processing to output to the specified  file  in  MPEG-4
              AAC ADTS format

       -b &lt;number&gt;, --bits &lt;number&gt;
              Set  the output (individual) sample format. The number takes one
              of the following values:
                     1: 16-bit PCM data (default).
                     2: 24-bit PCM data.
                     3: 32-bit PCM data.
                     4: 32-bit floatingint data.
                     5: 64-bit floatingint data.

       -d , --downmix
              Set the processing to downsample from 5.1  (surround  sound  and
              bass) channels to 2 channels (stereo).

       -f &lt;number&gt;, --format &lt;number&gt;
              Set  the output file format. The number takes one of the follow-
              ing values:
                     1: Microsoft WAV format (default).
                     2: Raw PCM data.

       -g     Set the processing to not perform gapless decoding.

       -h , --help
              Shows a usage summary.

       -i , --info
              Shows information about the about the input file.

       -l &lt;number&gt;, --objecttype &lt;number&gt;
              Sets the MPEG    rofile and object type for  the  processing  to
              use. The number takes one of the following values:
                     1: Main object type.
                     2: Low Complexity (LC) object type (default).
                     4: Long Term Prediction (LTP) object type.
                     23: Low Delay (LD) object type.

       -o &lt;filename&gt;, --outfile &lt;number&gt;
              Sets the filename for processing output.

       -q , --quiet
              Quiet - Suppresses status messages during processing.

       -t , --oldformat
              Sets  the processing output to be sent to the standard out. Only
              raw PCM may be sent to the standard out, as headers cannot  cur-
              rently be streamed.

       -w , --stdio
              Sets the processing output to be sent to the standard out.
