Changing the pitch of a sound through QC?

[DusterdooSmock]

Is there a way to change the pitch of a sound that is being played through qc?
Sort of like the voicepitch for bots in CS:S, but I had another use in mind for it.

Not that I am aware of. I thought about it as well , but I guess you would need to port over a sound editing utility to the engine, and make up new paramaters for the sound commands in quake to modify them in game. I would imagine that it would soak up some decent CPU resources to convert sounds on the fly like that during the game.

void(entity e, float chan, string samp, float vol, float atten, float speedpct) soundpitch = #8;

identical to existing sound builtin. using random(80,120) or so gives a reasonable range to stop sounds from being quite so monotonous. and because its the same builtin number, its generally safe to call even if the engine doesn't support the extension, you'll just loose any randomised pitches, so its great for sound effects.
Works in FTE, and from what I hear also DP now, though you'll need a fairly recent build.

specifically, the added argument is a speed percentage. passing a value of 50 will make the sound play at half the speed and thus give it a lower pitch. exercise caution when using it for voice samples due to the duration changes.

Disclaimer: old versions of DP will explode due to not expecting the extra arg, no other engine will.

Darkplaces just added the ability to not too long ago. I also meant to add the ability to Engoo last year but the pitch value seemed to get lost in translation so I never did a release with it working

but when I do, i'll model it over DP's builtin

Wow, didnt know that !

#8 seems to be the regular sound command in my qc. Just substitute that in place, and I guess alter all the regular sound calls to meet the new one?

coder's choice. you can just have two separate #8 builtins defined, or use ... in the prototype so the qcc won't care if its there or not.

sounds like your dp client+server are not compatible with it and thus each other, specifically that the server supports it while the client does not.

a value of 100 is normal speed. you'll hear no difference from normal if the value is 100. the further away from 100 that it is, the greater the speed/pitch change.
