Graphic Data Entry

The latest version of the Sound Loom allows you to enter various types of control data by drawing them with the mouse over a graphic display of the waveform or spectrum of the source sound.
You can also play the source, or any part of the source, from the same display, while you are creating the data.

Marks, boxes or breakpoints are created by clicking or dragging the mouse, sometimes with the Control, Shift or Alt Key depressed.
