Use ``replaygain-clip=no`` to disable this. + ``replaygain-fallback`` + Gain in dB to apply if the file has no replay gain tags. This option + is always applied if the replaygain logic is somehow inactive. If this + is applied, no other replaygain options are applied. ``softclip`` Turns soft clipping on. Soft-clipping can make the sound more smooth if very high volume levels are used.
