I would also like to see the source, 'cause DLLs don't work in Linux. Wondering if it's using any windows API in it, that prevent it from compiling under Linux.

Thanks a lot for your lib pjay, loving it

For retro sound generator i'm using sfxr (http://code.google.com/p/sfxr/) (under Linux and Windows)
A purebasic version with your lib would be neat

Well, I just realized that the lib for 4.31 also works for 4.40 - maybe you should mention it in your first post or so.

Thanks for the info c4s, still haven't got around to testing it myself.

I think this is redundant now anyway, as Demivec had released his source.

Sure, his code is really good for adjusting every setting to generate the sound. The only bad thing is that it's way more complicated than yours where I just have to use CreateSpotFX() and I have my sound.

I like your lib and I'm using it in several projects so don't you wanna post the source for exactly this procedure? Or at least keep updating it as long as it's needed.

ok so i'm the only one who can't get it to work..

1. how do i tell it to use the library in the editor
2. when i try to run it it comes up with seed is already defined

but this may be just what i've been looking for for about 20+ years

(PS i too would like to see the source code and learn)

pjay,

I'm having a blast with your SpotFX library - thanks!

I noticed that your first message in this thread shows this syntax:
CreateSpotFX(Random Seed, SoundVolume (0-127), Mutate#,Sound# to catch to)

Shouldn't the "SoundVolume" and "Mutate" parameters be swapped?

Regards,
Eric

what am i doing wrong .. running win 7 and purebasic 4.40 ... cry ....

its not woorking

Posted: **Thu Jan 21, 2010 5:20 pm**

Just place the library itself in "PureBasic\PureLibraries\UserLibraries\", use the command CreateSpotFX() and everything should work fine.

Posted: **Fri Jan 22, 2010 1:48 am**

ok i've done that and now its coming up with

---------------------------
PureBasic
---------------------------
The following PureLibrary is missing: Misc2.
---------------------------
OK
---------------------------

Posted: **Fri Jan 22, 2010 7:55 am**

Ok I have it working finaly.. it turns out i'd d/loaded the oine for an earlier version of PB that used a non exsistant library (Misc2)

now I just have to find a way or someone to combine the 2.

this one from PJ and the one from Demivec so that Demivec's one can use the command line or so that PJ's one can uise the sliders to build specific combo's to generate the CreateSpotFX() line ..
at the moment PJ's is hit and mis till you get one you like.
at the moment Demivec's one outputs to a wav file.

I'd like to see one that can do both / either or ..

I did notice that the save function (not generate wave) saves the data needed to re-load back in .. all it really needs now is a way to add that raw data thoe a statement line really .. and break it up into the different slider inputs as opposed to a big number mashed together .. so that you can tinker with it

but alas i'm way too new to PureBasic and i'm already hopelessly lost
I know what i want but not how to get it... lol

this is definatly the closest i've been to my "Holey Grail" that i've been searcdhing for for over 20 years

Any help would greatly be appreciated

I would be interested in your sourcecode, if you don't mind to release it open.

point is, I never use UserLibs, but I'm interested in learning about the functionallity of sound generating.
could be a great deal for minigames to create any sound on the fly...

haha! This is awesome! I was driving my cat crazy with number 125536120 at mutate 36 and max volume!

Posted: **Tue Apr 27, 2010 9:47 pm**

pjay, I'm still a fan of this library but again it isn't compatible with PureBasic 4.50. Sure Demivec's version is better but otherwise I like how simple yours is.

Please don't let this project die! What about releasing the source code if you don't want to take care about it anymore?

Posted: **Wed Apr 28, 2010 6:39 pm**

Crikey.... sorry guys, I thought I posted this months ago

This is the code I have on my USB stick at the moment - looking at the timestamp on the file, it appears I've made some changes that weren't on the previous library (pure laziness on my behalf of not commenting what I've changed!).

Edits - Changed to be MacOS compatible - Made unicode friendly.
