OpenAL, do I need a dll?BlitzMax Forums/BlitzMax Programming/OpenAL, do I need a dll?
| OpenAL works fine on my BMax PC, but when I tested it on a WinMe PC SetAudioDriver("OpenAl") returns null. Am I supposed to have a dll in with my game? If so where can I find the dll! Thanks. |
| You need the OpenAL installer for Windows.|
| You actually don't need the installer. Just put the two openAL DLLs in your program folder, then call EnableOpenALAudio() and it'll all work fine.|
But yeah, you can get the DLLs from the installer. :)
| right OK thanks. So I don't recall ever running that installer on my PC and I haven't called EnableOpenALAudio, yet it works fine...|
On the other PC I definitely haven't installed it so I'll try including the dlls with the exe.
| Well, you don't actually NEED to use EnableOpenALAudio, but in doing so you enable several different OpenAL audio drivers (including the software mixer which I'd highly recommend using). |
| Why do I need the software mixer again? And what are the different OpenAL drivers? (Why can't there just be one, nice an simple! arg) |
| When I used the default OpenAL driver on my laptop, I couldn't get it to allocate more than six audio channels, while the same code worked fine on everybody else's PC (I posted a thread here about it).|
The software mixer didn't have this limitation.
Full list of drivers available (after EnableOpenALAudio):
OpenAL Generic Software *
OpenAL Generic Hardware
* = Driver I use under Vista
** = Driver I use under all other OS's
| Yeah I recall the other thread now. OK good advice thanks. So all I do is call EnableOpenALAudio and then use the Generic Software one and I can use more channels without any other fancy code? |
| Under most circumstances you can just use the OpenAL hardware driver. But as I said, you'll likely have channel problems like I did if your end user has crappy on-board sound hardware.|
The software mixer is fine, but it does come with a slight performance overhead which is why I use this driver as default on Vista only. I figure any PC that can run Vista will be fast enough to suffer the [small] performance loss.
| yeah I heard you say that before and I agree, so I'll do the same.|
Also tried Direct sound, but hacing some problems, I'll report soon.
| Sorry to dig this up, but what are the two dlls I need? |
I see openAL32.dll but what's the other one people are referring to?
| wrap_oal.dll |
| Nice one, thanks. :) |
