4 speaker rehearsals

[MasterGy]

Hi !

I want to ask for a little help!
I want to do the car game with good sounds, engine noise, etc.…
I tried adjusting the balance. The rehearsal works with 2 speakers, so in stereo.
Unfortunately I only have a 2 speaker system.
I would like someone to test with 4 speakers to see if it works that way.
Just enter an mp3 music at the beginning of the program and then the position of the mouse in the circle will give the sound.
Does it work this way with 4 speakers?
Thanks for trying!

Code: QB64: [Select]

1. sn = _SNDOPEN("engine_01.wav")
2.  
3.  
4. monx = 600
5.  
6. cent = monx / 2
7. rad = monx * .9 / 2
8.  
9. mon = _NEWIMAGE(monx, monx, 32): SCREEN mon
10. CLS
11. CIRCLE (cent, cent), rad
12. CIRCLE (cent, cent), 5
13.  
14. DO: _LIMIT 30
15.  
16.     WHILE _MOUSEINPUT: WEND
17.  
18.     IF _SNDPLAYING(sn) = 0 THEN _SNDPLAY sn
19.  
20.     'volume
21.     dis = SQR((cent - _MOUSEX) ^ 2 + (cent - _MOUSEY) ^ 2)
22.     IF dis > rad THEN dis = rad
23.     volume = 1 - 1 / rad * dis
24.     _SNDVOL sn, volume
25.  
26.     'balance (left-right)
27.     disx = cent - _MOUSEX
28.     IF ABS(disx) > rad THEN disx = rad * SGN(disx)
29.     disx = -1 / rad * disx
30.  
31.     'balance (reae-front)
32.     disy = cent - _MOUSEY
33.     IF ABS(disy) > rad THEN disy = rad * SGN(disy)
34.     disy = -1 / rad * disy
35.  
36.  
37.     _SNDBAL sn, disx, disy, , 1 'left
38.     _SNDBAL sn, disx, disy, , 2 'right
39.  
40. LOOP
41.  
42.

I have never been able to get sound from the QB64 to the rear speakers, but it is possible that I will have a mistake because the rear speakers usually play very quietly. In your program, I rotate the mouse sound left, center, and then right. The front / rear doesn't work, but as I say, it wants someone else to try it as well. I have Logitech 5.1 speakers and it also depends a lot on whether I have a dolby digital switch and a switch on the speaker driver. When I switch that switch, my subwoofer gains and weakens when I move the mouse in the Y axis, but the rear speakers still nothing.

So - please test it also someone else with 4.0 / 4.1 / 5.1 / 7.1 speakers

I would also be interested in someone else's result.

thanks Petr for trying it! it's a shame it doesn't work, even though it would have been interesting.
