Description: ffmpeg-normalize
        ================
        
        ffmpeg script for normalizing audio.
        
        This program normalizes media files to a certain dB level. The default is an
        RMS-based normalization where the mean is lifted or attenuated. Peak normalization is
        possible with the ``-m`` option.
        
        It takes any audio or video file as input, and writes the audio part as
        output WAV file. The normalized audio can also be merged with the
        original.
        
        Requirements
        ------------
        
        - Python
        - `ffmpeg` from http://ffmpeg.org/ installed in your `$PATH` (3.x or above recommended)
        
        Installation
        ------------
        
            pip install ffmpeg-normalize
        
        Usage
        -----
        
            ffmpeg-normalize [options] <input-file>...
        
        Options:
        
        -  ``-f``, ``--force`` — Force overwriting existing files
        -  ``-l``, ``--level <level>`` — dB level to normalize to [default: -26]
        -  ``-p``, ``--prefix <prefix>`` — Prefix for normalized files or output folder name [default:
           normalized]
        -  ``-x``, ``--no-prefix`` — Write output file without prefix (cannot be used when `--dir` is used)
        -  ``-t``, ``--threshold <threshold>`` — dB threshold below which the
           audio will be not adjusted [default: 0.5]
        -  ``-o``, ``--dir`` — Create an output folder under the input file's directory with the prefix instead of prefixing the
           file (does not work if `--no-prefix` is chosen)
        -  ``-m``, ``--max`` — Normalize to the maximum (peak) volume instead of
           RMS
        -  ``-v``, ``--verbose`` — Enable verbose output
        -  ``-n``, ``--dry-run`` — Show what would be done, do not convert
        -  ``-d``, ``--debug`` — Show debug output
        -  ``-u``, ``--merge`` — Take original file's streams and merge the normalized audio. Note: This will not overwrite the input file, but output to ``normalized-<input>``.
        -  ``-a``, ``--acodec <acodec>`` — Set audio codec for ffmpeg (see
           `ffmpeg -encoders`) (will be chosen based on format, default pcm_s16le for WAV)
        -  ``-r``, ``--format <format>`` – Set format for ffmpeg (see `ffmpeg -formats`) to use for output file [default: wav]
        -  ``-e``, ``--extra-options <extra-options>`` — Set extra options
           passed to ffmpeg (e.g. “-b:a 192k” to set audio bitrate)
        
        Examples
        --------
        
        Normalize a file and write to `normalized-file.wav`::
        
            ffmpeg-normalize -v file.mp3
            ffmpeg-normalize --verbose *.avi
        
        Normalize a number of AVI files and write to `normalized-<file>.wav`::
        
            ffmpeg-normalize -v *.avi
            ffmpeg-normalize --verbose *.avi
        
        Normalize a number of MP4 files to -5 dB peak volume and merge the audio stream back into the MP4 files, in a new directory called `normalized`::
        
            ffmpeg-normalize -vuofm -l -5 *.mp4
            ffmpeg-normalize --verbose --merge --dir --force --max --level -5 *.mp4
        
        Normalize a number of MKV files and merge the audio back in using the `libfdk_aac` encoder with 192 kBit/s CBR::
        
            ffmpeg-normalize -vu -a libfdk_aac -e "-b:a 192k" *.mkv
            ffmpeg-normalize --verbose --merge --acodec libfdk_aac --extra-options "-b:a 192k" *.mkv
