Finalization Procedures

final :: auto_finalize

  • public subroutine auto_finalize(self)

    An automatic finalizer, by security.

    Arguments

    Type IntentOptional Attributes Name
    type(tape_recorder), intent(inout) :: self

Type-Bound Procedures

procedure, public :: clear_tracks

  • public subroutine clear_tracks(self)

    Erase all tracks on all the channels of the tape.

    Arguments

    Type IntentOptional Attributes Name
    class(tape_recorder), intent(inout) :: self

procedure, public :: copy_section

  • public subroutine copy_section(self, from_track, to_track, t1, t2, t3)

procedure, public :: finalize

  • public subroutine finalize(self)

    Called by the close_WAV_file() method.

    Arguments

  • public subroutine mix_tracks(self, levels, pan)

    Tracks 1 to tracks-1 are mixed on track 0.

    Arguments

    Type IntentOptional Attributes Name
    class(tape_recorder), intent(inout) :: self
    real(kind=wp), intent(in), optional, dimension(1:self%tracks) :: levels
