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 program reads in MPEG‐4
       AAC files, processes, and outputs them in  either  Microsoft  WAV,  MPEG‐4  AAC  ADTS,  or
       standard PCM formats.

OPTIONS

       -a <filename>, --adtsout <filename>
              Sets the processing to output to the specified file in MPEG‐4 AAC ADTS format

       -b <number>, --bits <number>
              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 floating‐point data.
                     5: 64‐bit floating‐point data.

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

       -f <number>, --format <number>
              Set the output file format. The number takes one of the following 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 <number>, --objecttype <number>
              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 <filename>, --outfile <number>
              Sets the filename for processing output.

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

       -t , --oldformat
              Sets the processing to use the old MPEG‐4 AAC ADTS format when outputting  in  said
              format.

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