      seconds. A paused bank starts from silence where it was paused, and a
      completed bank starts again from the beginning. A bank which is fading out
      turns around from where the fade had reached. }
    procedure FadeIn(Seconds: Single);
    { Lower the bank to silence over a number of seconds and then pause it. Its
      position is kept, so FadeIn or Paused continues from there. }

      and Reserved are not changed. }

      bank is then paused. }
    property Completed: Boolean read FCompleted;
    { A paused bank is not decoded or mixed. The default is True. A bank without
      a source is always paused. Setting Paused to False plays at the volume of
      the bank at once, ending any fade. }
    property Paused: Boolean read FPaused write SetPaused;
    { The number of times to play before the bank is completed. A value of less
      than 1 plays until it is stopped, and reads back as 0. The default is 1. }

      0. }
    property Pan: Single read FPan write SetPan;
    { Position is the playback point in seconds. Setting it clears Completed and
      sets Loop to 0. Most formats move the position to the start of the nearest
      block they can decode from, so the value read back can differ from the
      value set. }
    property Position: Single read GetPosition write SetPosition;
    { Volume ranges from 0 for silence to 1. The default is 1. Volume reads as 0
      while the bank is muted. }

      be loaded directly }
