[12:06:02] <nitrotrigger> how do I convert std::string to ALbyte* for the first argument of alutLoadWAVFile()?
[12:06:18] <nitrotrigger> I'm getting error for passing std::string::c_str()
[12:07:46] <KittyCat> cast it to a const ALbyte*
[12:07:57] <KittyCat> might need to use reinterpret_cast
[12:09:42] <nitrotrigger> could you give me an example?
[12:10:01] <nitrotrigger> I haven't done casting much
[12:10:40] <KittyCat> alutLoadWAVFile(reinterpret_cast<const ALbyte*>(some_string.c_str()), ...)
[12:11:34] <KittyCat> might be better to use alutCreateBufferFromFile, though. alutLoadWAVFile is deprecated
[12:11:52] <nitrotrigger> what's the difference?
[12:12:37] <KittyCat> alutCreateBufferFromFile will return an AL buffer directly, instead of having to load the data, create the buffer, and buffer the data
[12:13:39] <nitrotrigger> error: invalid conversion from ?const ALbyte*? to ?ALbyte*?
[12:15:08] <KittyCat> remove the const from the cast
[12:15:35] <nitrotrigger> error: reinterpret_cast from type ?const char*? to type ?ALbyte*? casts away constness
[12:16:17] <KittyCat> try const_cast instead of reinterpret_cast
[12:16:44] <nitrotrigger> it worked
[12:16:52] <nitrotrigger> now I'm getting only warnings
[12:17:19] <nitrotrigger> alutLoadWAVFile is deprecated...
[12:18:36] <nitrotrigger> http://rafb.net/p/yW6rXA59.html
[12:23:17] <KittyCat> alutCreateBufferFromFile is probably a better choice to use. but the code looks alright
[12:23:59] <nitrotrigger> :)
[12:29:25] <nitrotrigger> btw. should I delete buffer or source first?
[12:31:31] <KittyCat> the source, usually
[12:33:29] <nitrotrigger> http://www.devmaster.net/articles/openal-tutorials/lesson1.php
[12:33:36] <nitrotrigger> is this doing it wrong?
[12:36:08] <KittyCat> quite wrong, actually..
[12:36:31] <KittyCat> it needs to stop the source before trying to delete it, and it needs to make sure the buffer isn't attached to a source before deleting it
[12:36:54] <nitrotrigger> then I'm doing it wrong too
[12:38:26] <nitrotrigger> how to detach a source from buffer?
[12:42:10] <KittyCat> attach buffer 0 to the source
[12:42:25] <KittyCat> or delete the non-playing source
[12:44:09] <nitrotrigger> http://rafb.net/p/v8jW3t16.html
[12:44:12] <nitrotrigger> something like this?
[12:44:48] <KittyCat> looks good
[12:45:27] <nitrotrigger> alSourceStop() is always safe to call?
[12:46:30] <nitrotrigger> btw. OpenAL really needs a good tutorial
[12:47:15] <nitrotrigger> my google-skills were enough for only that one
[12:49:34] <KittyCat> yeah, there doesn't seem to be many good tutorials
[12:49:49] <KittyCat> I made a tutorial, but it's a bit more advnaced usage than most
[12:49:55] <KittyCat> *advanced
[12:51:07] <nitrotrigger> btw. (ALbyte*) fname.c_str() was enough
[12:51:47] <KittyCat> C++ discourages casting that way
[12:52:15] <nitrotrigger> I'll then stick in your solution
[12:53:07] <KittyCat> C++ tends to prefer the uglier some_cast<type>(foo), to discourage such casting all together, and just rely on inheritence
[13:16:14] <nitrotrigger> http://rafb.net/p/u3Bp3z33.html
[13:17:46] <nitrotrigger> should I make a buffer queue or something to prevent the sound to stop while the next loop continues?
[13:18:19] <nitrotrigger> it sounds like the sample is being played and then I can easily hear it starting again
[13:20:42] <nitrotrigger> argh
[13:20:48] <nitrotrigger> my sample is broken :(
[13:21:18] <KittyCat> if there's a break in the playback loop, yeah. openal shouldn't introduce any breaks
[13:22:15] <nitrotrigger> btw. do you know any good wav editing programs?
[13:22:33] <nitrotrigger> I want to get the stable engine sounds
[13:22:58] <KittyCat> only one I'm really familiar with is audacity. but it had a bit of a clunky UI
[13:22:58] <nitrotrigger> but all I have are sort of accelerating sounds
[13:23:16] <nitrotrigger> I've tried it, and it didn't have the feature I need
[13:23:48] <nitrotrigger> I actually made a suggestion to the audacity to add that feature

[15:22:50] <rsp> Hi
[15:23:05] <KittyCat> hi
[15:25:01] <rsp> Have you tried Ubuntu 8.04? :)
[15:29:20] <KittyCat> nope
[15:40:05] <rsp> Ok, it rocks
[15:46:32] <rsp> How can I add some cool realtime effects
[15:49:20] <rsp> reverb for example
[15:52:34] <KittyCat> the AL_EXT_EFX
[15:52:39] <KittyCat> extension
[15:52:58] <KittyCat> openal soft provides the standard reverb effect
[15:53:12] <KittyCat> details can be found in creative's openal sdk
[15:53:23] <rsp> Thanks
[15:53:29] <rsp> Are you going to add more of them
[15:53:53] <rsp> Or do you mean reverb was one of them
[15:53:59] <KittyCat> not sure. depends on how efficiently they can be done in software
[15:54:06] <rsp> Ok
[15:54:14] <KittyCat> reverb is the only effect. but it also does the lowpass filter
[15:56:01] <rsp> Cool
[15:57:44] <KittyCat> and things associated with it (eg. air absorption, cone gainhf)
[15:58:04] <rsp> Ok!

[16:10:39] *** barra_library has joined #openal
[16:11:06] <barra_library> hello
[16:11:10] <barra_library> ping KittyCat
[16:11:13] <KittyCat> hi
[16:11:36] <barra_library> I've built openal_soft from source on win32, activated the dsound backend as well
[16:12:26] <barra_library> I've build our engine against openal_soft, I don't hear any sound when I run the engine while sound plays fine if I replace the openal_soft.dll with a renamed openal32.dll from creative
[16:13:57] <KittyCat> how are you opening the device?
[16:14:16] <barra_library> btw.: I've used the 1.3.253 release
[16:14:21] <barra_library> let me try to find the code
[16:15:47] <barra_library> I guess the answer is hidden in here KittyCat: http://mirror1.cvsdude.com/trac/fife/engine/browser/trunk/engine/core/audio/soundmanager.cpp
[16:16:01] <barra_library> though I'm no programmer, sorry :-/ for which line should I search for?
[16:16:36] <barra_library> I guess that's the relevant line? >> m_device = alcOpenDevice(NULL);
[16:17:27] <KittyCat> hmm.. that looks alright to me
[16:17:50] <KittyCat> though you shouldn't just set m_device to NULL if there's an error. you should close the device if it's open
[16:18:42] <barra_library> I see, we don't really have an active audio programmer on the team ATM but I'll create a ticket for it later
[16:18:52] <KittyCat> the default orientation looks weird..
[16:19:29] <KittyCat> should be { 0.0, 0.0, -1.0, 0.0, 1.0, 0.0} for straight-ahead
[16:20:30] *** Walt has quit IRC
[16:20:32] <barra_library> but that shouldn't influence if I get sound on win32 I guess?
[16:20:52] <KittyCat> depends on how it works
[16:21:14] <KittyCat> it could implicitly fix it
[16:21:28] <barra_library> I tested openal_soft on win32 about 2 weeks ago and I thought that it worked but I was wrong; I've built it as openal32.dll and it seems it has used the creative DLL with the same name instead of openal soft so sound worked but openal_soft was not used
[16:25:02] <barra_library> oki, I've changed that according to your proposal, rebuidling ATM
[16:28:42] <barra_library> nope, no sound yet :-/
