Sound effects experimentation - kevin - 01-20-2024
I love the new sound effects in the latest N7 version. I am working on this program to let me see the effects of changing the various parameters that you need to use when creating the sound effects.
You need to click the mouse when inside the blue buttons to change the paramenters, and click the red button to play the new sound.
I've only incorporated one of the new functions so far, and spent little time on aesthetics, as you can see.
I'll leave this now until tomorrow, and see whether I can think of any changes that I can make, before moving on to the other 2 functions. In the meantime, I would love to hear any suggestions for improvements that you may have?
All the best - Kevin.

Ah, that makes it a lot easier to find good parameters
I added a hack to unflag the mousebutton when the user clicks "PLAY SOUND", because I kept getting multiple instances of the sound effect playing.
Code:
...
if mousebutton(0)
if mousey() > 60 and mousey() < 110
if mousex() > 20 and mousex() < 220
tmp = mousebutton(0, true) ' mousebutton will return false until it has been
' released and pressed again.
play_sound = true
laserShotSnd = CreateSquareSfx(duration, startFreq, endFreq, fadeOut, sampleRate)
play sound laserShotSnd
endif
endif
endif
...Maybe I should write some examples on how to use the ngui library that NED and all the included editors are using. It makes it easier to make these type of programs.

I've had a look at the ngui library in the past for this type of program, but wasn't able to work out how to apply it, so I would certainly appreciate seeing some examples Marcus.

Now added the other 2 functions, and incorporated Marcus's fix for playing sound:
Code:

Kevin,
Firstly... Cool additions... Immediately drawn to the "noise" generator... "Pitch" may need a "tweak". I wanted to see how "low" it would go... you know for explosions etc... The slider, using the mouse, can get it down to "-0". Yep. That's a minus... "invalid pitch" error... getting the pitch down to "0.05" works fine...

Johnno,
Thank you so much for finding that. I've fixed the code above. If you just want to change the code in your saved program, you will need to change lines 480 & 481 to this:
Code:
elseif mousex() > screen_w - 220 and mousex() < screen_w - 220 + pitch3 * 200/5
pitch3 = max(0.01,pitch3 - 0.05)Line 480 has nothing to do with the -0 issue, but caused a different issue where the slider would move to the left even though the mouse was to the right, but outside of the blue box.
I note that if line 481 is set to "pitch3 = max(0.00,pitch3 - 0.05)" it still causes a crash, so I assume that pitch has to be > 0.
I have absolutely no idea why the value was showing as -0.0 (negative), but the above seems to fix it. I can only assume that there is an issue with rounding.
RE: Sound effects experimentation - johnno56 - 01-21-2024
Kevin,
That fix worked fine. The lowest is now "0.01". Thank you for the fix. Much appreciated.
