=head1 NAME
L<dtas-player(1)> effects overview
=head1 DESCRIPTION
Effects in dtas-player may be applied either at the source or the sink.
They are applied in the order described.
=over
=item 1. source effects
Source effects are effects which should be applied per-source and do not
rely on inter-track information.
Examples include:
=over
=item ReplayGain (simple gain changes)
=item anything which does not change the length of the audio:
gain, stereo, highpass, lowpass, loudness, bass, treble, equalizer, ...
=back
Modifying source effects should introduce no extra gaps in playback.
Effects which modify the length of the audio is not recommended here,
as seek functionality will be impaired.
=item 2. sink effects
Sink effects are any effects which:
=over
=item 1) should only be applied to a specific sink
=item 2) effects which require inter-track information
(multiband delays/compressors/expanders)
=item 3) alter the length of the audio
=back
In a multi-zone audio system (where each zone has its own sink), sink
effects may also customize the sound of a certain zone while not
affecting others.
Examples include:
=over
=item equalizer effects (highpass/bass/treble/equalizer)
=item loudness
=item delaying a certain channel or frequency range for time-alignment
=item compressors/limiters
=item reverb
=item gain
=item remix (for stereo image adjustments)
=back
Additionally, effects which are necessary due to the limitation of the
playback hardware are applied at the sink:
=over
=item rate
=item dither
=item remix (static channel mappings)
=back
=back
