Long description
This is an interactive that may be used to record sound and display a visual representation of it on the screen. The recorded sound is shown as a series of vertical pink lines between positive and negative voltages, representing the sound amplitude. The horizontal bunching of these lines represents frequency. When the sound is played, a vertical cursor moves from left to right across the screen to show the user where they are in the recording. The control bar is at the bottom with two buttons, Record and Play, on the left, followed by some numbers that show the position of the cursor and the total length of the recording. At the right of the control bar is a Full Screen button. Below the control bar is a Zoom slider that allows the user to zoom in to the visual representation at the current location of the cursor. Because this interactive changes visually according to the nature of the recorded sound, you may need a sighted helper to describe the results to you.
