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

This utility provides a command line interface to libfaad2. This program reads in MPEG\(hy4 AAC files, processes, and outputs them in either Microsoft WAV, MPEG\(hy4 AAC ADTS, or standard PCM formats.

-a <filename>, -\^-adtsout <filename>

Sets the processing to output to the specified file in MPEG\(hy4 AAC ADTS format

-b <number>, -\^-bits <number>

Set the output (individual) sample format. The number takes one of the following values:

1: 16\(hybit PCM data (default).

2: 24\(hybit PCM data.

3: 32\(hybit PCM data.

4: 32\(hybit floating\(hypoint data.

5: 64\(hybit floating\(hypoint 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\hy(4 profile 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\(hy4 AAC ADTS format when outputting in said format.

-w , -\^-stdio

Sets the processing output to be sent to the standard out.
