How to Synchronize Animation to a Specific Time within a Sound Object

This tutorial has already shown how to set a variable to equal a specific time within a sound object using the mySoundObject.position property. The following is a simple trick for capturing the exact positions you need.

Fig. 15: Example of synchronizing animation to a time position of a sound object

For the Flash example Fig. 15 above, to display the "7" animation, the following code was used:

if (playing==true && mySound.position/1000 >= 8.5 && mySound.position/1000 <= 9.5) {

In the above example, when the sound object "mySound" reached 8.5 seconds, the contents of a dynamic text box with the variable name of "numbersText" was changed to "7".

If you have an audio file in which the positions you wish to capture are very close together, you could use the following player to capture a sound position on mouse click.
