6.9 3D sound

This sound driver supports the following two types of 3D sound. The types of localization and number of channels that can be specified are as follows. Specify any panorama with the “3D control (11h)” or “Qsound control (12h)” command of the sound control command. The virtual sound source moves to the specified location.

Since the movement of the virtual sound source is often random for both Q and YAMAHA3D sounds, the main system controls all of the panning movements. The sound driver simply moves the sound image to the specified location. However, if you need a simple linear movement, or if you want the sound driver to have a little more intelligent control, you can do it for each project as needed.

As DSP expansion module of YAMAHA, 4 kinds of DSP programs of Q sound 4ch, Q sound 8ch, YAMAHA 3D sound 1ch, YAMAHA 3D sound 2ch are prepared, so when using 3D sound, the above 4 kinds of DSP Download the necessary DSP program from the programs using the “Effect Change (83h)” command.

6.9.1 Q Sound

You can swing a wide-angle PAN up to 180 degrees left and right. The pan type is only PAN, but up to 8 channels can be controlled simultaneously.

 channel (0-7): 4 channels (0-3) or 8 channels (0-7) can be specified.
PAN position (0-30): 15 is the center, and up to 15 levels of PAN can be shaken. 

6.9.2 YAMAHA 3D sound

The virtual sound source can be moved to any position in 360 degrees, 128 steps in height and 128 steps in distance. The number of channels used is 1 channel, but you can specify any position up / down / left / right.

 Distance (0-127): The value is 0, the distance is 0, and the distance increases as the value increases.
Azimuth (0-127): Specify 360 degrees of horizontal orientation in 128 steps. 0 for front, 32 for right
〇90 degrees, 64 right behind, 96 left 90 degrees.
Height (0-127): Specify the height in 128 steps. A value of 0 is directly below, 32 is the eye height, 64
, Just above, 96 behind.
