faad — Process an Advanced Audio Codec stream

       Matthew W. S. Bell <matthew (at) bells23.org.uk>

       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.

-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.
