[не удалять] Обработка и пересжатие звуковых дорожек [архив №2]

Usage:
faad [options] infile.aac
Options:
 -h    Shows this help screen.
 -i    Shows info about the input file.
 -a X  Write MPEG-4 AAC ADTS output file.
 -t    Assume old ADTS format.
 -o X  Set output filename.
 -f X  Set output format. Valid values for X are:
        1:  Microsoft WAV format (default).
        2:  RAW PCM data.
 -b X  Set output sample format. Valid values for X are:
        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.
 -s X  Force the samplerate to X (for RAW files).
 -l X  Set object type. Supported object types:
        1:  Main object type.
        2:  LC (Low Complexity) object type.
        4:  LTP (Long Term Prediction) object type.
        23: LD (Low Delay) object type.
 -d    Down matrix 5.1 to 2 channels
 -w    Write output to stdio instead of a file.
 -g    Disable gapless decoding.
 -q    Quiet - suppresses status messages.
Example:
       faad infile.aac
       faad infile.mp4
       faad -o outfile.wav infile.aac
       faad -w infile.aac > outfile.wav
       faad -a outfile.aac infile.aac

Usage:
neroAacEnc.exe [options] -if <input-file> -of <output-file>
Where:
<input-file>  : Path to source file to encode.
                The file must be in Microsoft WAV format and contain PCM data.
                Specify - to encode from stdin.
                Note that multiple input files can be specified, they will be
                encoded together into a single output file with chapter marks
                indicating source file divisions.
<output-file> : Path to output file to encode to, in MP4 format.
  ==== Available options: ====
Quality/bitrate control:
-q <number>   : Enables "target quality" mode.
                <number> is a floating-point number in 0...1 range.
-br <number>  : Specifies "target bitrate" mode.
                <number> is target bitrate in bits per second.
-cbr <number> : Specifies "target bitrate (streaming)" mode.
                <number> is target bitrate in bits per second.
                When neither of above quality/bitrate options is used,
                the encoder defaults to equivalent of -q 0.5
Multipass encoding:
-2pass        : Enables two-pass encoding mode.
                Note that two-pass more requires a physical file as input,
                rather than stdin.
-2passperiod  : Overrides two-pass encoding bitrate averaging period,
  <number>    : in milliseconds.
              : Specify zero to use least restrictive value possible (default).
Advanced features / troubleshooting:
-lc           : Forces use of LC AAC profile (HE features disabled)
-he           : Forces use of HE AAC profile (HEv2 features disabled)
-hev2         : Forces use of HEv2 AAC profile
                Note that the above switches (-lc, -he, -hev2) should not be
                used; optimal AAC profile is automatically determined from
                quality/bitrate settings when no override is specified.
-ignorelength : Ignores length signaled by WAV headers of input file.
                Useful for certain frontends using stdin.
