Algorithm
The Time and Pitch parameters can be set by typing numbers in the appropriate boxes, or by dragging
the sliders or the crosshair in the graph. Holding Shift while dragging the crosshair snaps the crosshair
to the nearest axis: X (time), Y (pitch), or the diagonal (equal time and pitch). Diagonal values on the
graph can be processed very quickly and with very high quality, but have the trade-off that changing
pitch does not preserve duration, and vice versa.
For the most natural-sounding results, choose low settings; transpose by no more than a third or a
fourth. Higher values, though, can be used for special effects.
To Apply Time/Pitch Stretch to Audio Data
1. Select the audio data to be affected.
2. Choose Audio Effects-Cakewalk-Time/Pitch Stretch from the Process menu or from the popup
menu to open the Cakewalk FX Time/Pitch Stretch dialog box.
3. Set the time/pitch stretch parameters, as described in the table above.
4. Click OK.
SONAR applies the time/pitch stretch to the selected data.

The crossfade amount for the blocks.
The accuracy of the calculations. Normal is good for most
sounds. High accuracy gives slightly better quality, but takes
longer to process.
The algorithm used for pitch stretching. The MPEX algorithm is
the default. Select Normal if you want to use the same
algorithm used by previous versions of SONAR.
