Default: ``command``.
- **overwrite**: Re-analyze files that already have ReplayGain tags.
Default: ``no``.
- **targetlevel**: A number of decibels for the target loudness level.
Default: 89.
- **targetlevel**: A number of decibels for the target loudness level for files
using ``REPLAYGAIN_`` tags.
Default: ``89``.
- **r128_targetlevel**: The target loudness level in decibels (i.e.
``<loudness in LUFS> + 107``) for files using ``R128_`` tags.
Default: 84 (Use ``83`` for ATSC A/85, ``84`` for EBU R128 or ``89`` for
ReplayGain 2.0.)
- **r128**: A space separated list of formats that will use ``R128_`` tags with
integer values instead of the common ``REPLAYGAIN_`` tags with floating point
values. Requires the "ffmpeg" backend.

- **peak**: Either ``true`` (the default) or ``sample``. ``true`` is
more accurate but slower.
This option is deprecated:
- **method**: The loudness scanning standard: either `replaygain` for
ReplayGain 2.0, `ebu` for EBU R128, or `atsc` for ATSC A/85. This dictates
the reference level: -18, -23, or -24 LUFS respectively. Only supported by
"bs1770gain" backend.
