If you don't have separate audio clips for each of the six channels required for
Dolby Surround mixing, MediaStudio Pro will generate the channels
automatically. The only requirement for automatic splitting of the single
stereo clip into six channels is that Dolby Surround Sound must be activated
in the project settings.
In the following example, we will create a mix of a hopping sound that jumps
among the three front speakers. This simple effect could be used in many different
situations - echo in the mountains, screams from the crowd, random shots, etc. -
all can be mixed in the same way.
To create a panning sound mix:
1. Insert a sound clip longer than 6 seconds into the Audio1 track. Make sure it
starts off at the beginning of the track.
2. Cut the clip at 2 and 4 seconds.
3. Move the two-to-four seconds part to the Audio2 track. Offset it slightly,
moving forward in time.
4. Repeat the same step with the four-to-six part, placing it on track Audio 3.
5. In the Audio Mixing Panel, click on the yellow dot in the middle of the
leftmost Audio 1 pan window. Drag it to the upper left corner of the window.
6. Repeat the step in the Audio 2 pan window, dragging the dot to upper center.
7. Do the same in Audio 3, putting the dot in the upper right corner.
8. Click the Play button to stream the mix. Notice how the sound pans from left to
right. Try placing audio clips on more than three tracks, experiment with sound
volume and position controls.
To edit the volume of the center channel, adjust the Center
slider. Similarly, to edit the volume of the Low Frequency Effect
(LFE) channel, adjust the LFE
window.
To edit the volume of the surround mix as a whole, adjust the Master
volume slider.
The more advanced mixes would include far more than just three clips of the same
source.
