In AS, treatments as a whole, are symbolized as "container", represented by blocks in the Processing Sequencer and by the superior band of the BPF in the Sonogram Window. The dynamic behaviour of the treatment is represented by a BPF. The transposition, melodic transposition and frequency shift parameters can be modified via the Sonogram or Inspector windows and Processing Sequencer.
The block can be moved and resized in time, which will affect the BPF's profile and values.
The BPF can be edited manually, creating and manipulating points from its internal editor.
For more information about all possible manipulations and edition operations, refer the corresponding section.
The transposition BPF is selected by default.
To select a BPF,
To hide an unselected BPF, choose
The transposition factors can be reset reopening the Tranposition dialogue window with a double click on the block in the Processing Sequencer. If a BPF has been edited, all its values will be reset. A dialogue window will ask you to confirm your choice.
The constant value of the BPF is displayed on the left, with a scale and grid corresponding to the maximum and minimum displayed values specified in the Inspector. The space between the grid's segment varies with the sonogram window's height. Its values depend on the min and max values.
When the container is selected, its parametric values can be visualized and edited in the Inspector. These parameters can regard constant, dynamic and/or melodic transposition.
Two options are related with melodic transposition, and cannot be modified :
Melodic : this option actually indicated whether you have chosen to execute a melodic transposition or not.
Use Annotation : melodic transposition is automatically based on annotations.
Visible Range Min and Max : these are the visible boundaries of the transposition, which are designed to improve the BPF visualization, but do not limitate it. The maximum up and down transposition limits are equal to 3600 or -3600 cents for the transposition BPFs, and to a value in Hz that depends on the sonogram's frequency limits.
X and Y : coordinates of a selected point in cents and seconds. If several points are selected, these will be those of the first point.
