Story

As a user
I want a stop button
so that I am able to stop the music when desired instead of having to close the application.

Acceptance Criteria

• There is a user interface input element that indicates selecting it will stop currently playing sound
• Selecting at element stops the currently playing sound rendering

Supporting Information

At present, when a user opens an image and starts audio rendering, the "music" only stops when it reaches the end of the image data or the program is halted. Closing the image window does not interrupt the audio rendering so the music will continue to play. Adding a "stop playing" control would allow the user to stop the music when they want to.

Note that the meaning of the "stop" control needs to be well-defined. For example, is "stop" associated with a particular image rendering, thus there would be multiple "stop" controls, each associated with a specific image being "played"? Is "stop" a global control that will interrupt all audio renderings that are currently playing? If "stop" is associated with a particular image, if the associated window is closed is the ability to "stop" lost? Does closing the visual rendering necessarily stop the audio rendering?

I would recommend this button be added under the play button.

I replaced the word "button" with "control" so that a wider range of user interface elements can be considered.
Note that "menu items" are currently the primary form of interaction within ImageLab.

This issue needs sketches of user-experience design alternatives from which we can choose. We might want prototypes to try out as well before making the decision.
