ZDoom

Well, as the title says, I'd like a function where you can specify and force the pitch the sound is played at. Not a fancy way, just changing the sample rate as ZDoom already does.

Maybe it could be done as an extension to the original A_PlaySound:

A_PlaySound(sound whattoplay = "weapons/pistol", int slot = CHAN_BODY, double volume = 1.0, bool looping = false, double attenuation = ATTN_NORM, bool local = false, double pitch = 1.0, bool randompitch = true);

So a pitch of 0.5 would half the sample rate, and randompitch determines whether the random pitching (if enabled and set in SNDINFO) should still be factored in on top of it.

A_PlaySound has been extended with a pitch parameter. A setter function has also been added.

As well as a starting pitch for A_PlaySound directly, too.

I shouldn't have to say this but some people asked me about A_PlaySoundEx, and failed to realized it's deprecated: No. Never. Deprecated means it's no longer going to be updated. End of story. Use A_PlaySound instead.
