       Usage: rsgain custom [OPTIONS] FILES...

       Custom Mode allows the user to specify the options to scan files with.

       The list of files to scan must be listed explicitly after the options.

   OPTIONS-h, --help
              Show help.

       -a, --album
              Calculate album gain and peak.

       -S, --skip-existing
              Don't scan files with existing ReplayGain information.

       -ss, --tagmode=s
              Scan files but don't write ReplayGain tags (default).

       -sd, --tagmode=d
              Delete ReplayGain tags from files.

       -si, --tagmode=i
              Scan and write ReplayGain 2.0 tags to files.

       -ln, --loudness=n
              Use n LUFS as target loudness (-30 ≤ n ≤ -5).

       -cn, --clip-mode=n
              No clipping protection (default).

       -cp, --clip-mode=p
              Clipping protection enabled for positive-gain values only.

       -ca, --clip-mode=a
              Clipping protection always enabled.

       -mn, --max-peak=n
              Use max peak level n dB for clipping protection.

       -t, --true-peak
              Use true peak for peak calculations.

       -L, --lowercase
              Write lowercase tags (MP2/MP3/MP4/WMA/WAV/AIFF).
              This is non-standard but sometimes needed.

       -Ikeep, --id3v2-version=keep
              Keep file's existing ID3v2 version, 3 if none exists (default).

       -I3, --id3v2-version=3
              Write ID3v2.3 tags to MP2/MP3/WAV/AIFF.

       -I4, --id3v2-version=4
              Write ID3v2.4 tags to MP2/MP3/WAV/AIFF.

       -od, --opus-mode=d
              Write standard ReplayGain tags, clear header output gain (default).

       -or, --opus-mode=r
              Write R128_*_GAIN tags, clear header output gain.

       -os, --opus-mode=s
              Same as 'r', plus override target loudness to -23 LUFS.

       -ot, --opus-mode=t
              Write track gain to header output gain.

       -oa, --opus-mode=a
              Write album gain to header output gain.

       -O, --output
              Output tab-delimited scan data to stdout.

       -Os, --output=s
              Output with sep header (needed for Microsoft Excel compatibility).

       -Oa, --output=a
              Output with files sorted in alphanumeric order.

       -p, --preserve-mtimes
              Preserve file mtimes.

       -q, --quiet
              Don't print scanning status messages.

rsgain (really simple gain) is a ReplayGain 2.0 command-line utility.

       It applies loudness metadata tags to audio and video files while leaving the audio stream untouched.

       A ReplayGain-compatible player will dynamically adjust the volume of your tagged files during playback.

       rsgain supports writing tags to the following file types:
         - AIFF (.aiff, .aif, .snd)
         - APE (.ape)
         - FLAC (.flac)
         - MP2 (.mp2)
         - MP3 (.mp3)
         - MP4 (.m4a)
         - Musepack (.mpc)
         - Ogg (.ogg, .oga, .spx)
         - Opus (.opus)
         - TAK (.tak)
         - WAV (.wav)
         - WavPack (.wv)
         - WMA (.wma).

   OPTIONSANDCOMMANDS-h, --help
              Show help.

       -v, --version
              Show version number.

       easy   Easy Mode:
              Recursively scan a directory with recommended settings.
