[02:14:14] <KittyCat> okay, so I have a skeleton app. does opengl/openal initialization and shutdown, with a basic (empty) render loop and input controls.
[02:14:24] <KittyCat> what could I do to make a good openal demo?
[02:19:39] <KittyCat> also, how useful would some sample-accurate controls be? (eg. start/stop/change a source at a precise time measured in samples)
[02:23:47] <kb1ooo> that'd be useful for me.
[02:35:10] <kb1ooo> i'm pretty much an audio n00b.  I've been interested in openal, not for 3D sound, but for its portability.
[02:35:36] <kb1ooo> it'd be nice to see a few examples focussed on porting to openal..
[02:36:47] <KittyCat> I'd imagine sample-accurate controls would mainly be useful for things like rendering midi or module files. not something you'd typically want to do in a game, but perhaps as a stand-alone listening/converter app
[02:36:53] <kb1ooo> e.g. most other APIs are either block, or use callbacks.  OpenAL doesn't use either mechanism.
[02:38:00] <kb1ooo> it'd be useful for me because some of the apps that I'm interested in use the soundcard as a high precision timer, simultaneously while streaming audio.
[02:38:47] <KittyCat> the actual readable timer would likely be as accurate as the update size
[02:39:32] <KittyCat> but the actual mixer can use it as a base value and break/start the mixing at specific points
[02:40:29] <KittyCat> eg.
[02:40:49] <KittyCat> alGenTimers(1, &timer);
[02:41:19] <KittyCat> alTimerStartSource(timer, source, pos);
[02:41:29] <KittyCat> alTimerStart(timer);
[02:41:45] <KittyCat> then once the timer gets to 'pos' samples, the source will automatically start
[02:42:25] <KittyCat> alTimerBegin would probably be a better name to start it, actually..
[02:43:10] <KittyCat> and you'd have alTimerEnd to stop, alTimerReset to reset it back to 0, alTimerRead to read the current position, etc..
[02:45:58] <KittyCat> with source loop points and control for changing the various source parameters (eg. gain, pitch, position), I could imagine being able to render a midi file rather accurately
[02:46:12] <kb1ooo> cool
[02:46:49] <KittyCat> but I can't really think of much use beyond that, except maybe properly timed music fades
[02:47:53] <kb1ooo> that's what'd I'd use it for :)

[10:17:58] <KittyCat> well, I have a working proof-of-concept streaming api working for freealut, with both C and C++ interfaces

[17:22:01] <nitrotrigger> is openal v0.099 old?
[17:33:28] <nitrotrigger> http://rafb.net/p/S8n3EZ64.html
[17:37:10] <nitrotrigger> aww, looks like I need alut
[19:47:49] <prophile> nitrotrigger: yes
[19:48:41] <nitrotrigger> but how did it guess that alutInit() returns void?
[19:49:11] <prophile> C or C++?
[19:49:16] <nitrotrigger> C++
[19:49:23] <prophile> not a clue
[19:49:31] <nitrotrigger> "Pasted as C++ by nitrortrigger"

[23:38:16] <KittyCat> that must be an old alut
