AirPlay volume-control attenuates volume (gain) by up to -30dB: the decibel range -30:0 can be rescaled from _Low_:0, or _Low_:_High_, using the
option `-db` ("-db _Low_ " or "-db _Low_:_High_ "), _Low_ must be negative. Rescaling is linear in decibels. The
option ```-taper``` provides a "tapered" AirPlay volume-control

Note that GStreamer's audio format will "clip" any audio gain above +20db, so keep *High* below that level. The

The -vsync and -async options
also allow an optional positive (or negative) audio-delay adjustment in _milliseconds_ for fine-tuning : `-vsync 20.5`
