[Gambas-user] R: OpenAL (gb.openal) example code and problem loading .wav files
the function to load a .wav file into an audio buffer in order to play it. The latter doesn't work, however. The alure class seems to be similar to glu in that it's a high-level helper class to make common functions easy, such as loading sound files directly. This line should load the .wav file into the buffer We can use no Alure Class to load a .wav file into an audio buffer. We can load directly the row audio data of a wav file in 3th parameter of Al.BufferData() method. vuott Ven 21/8/15, Kevin Fishburne kevinfishbu...@eightvirtues.com ha scritto: Oggetto: [Gambas-user] OpenAL (gb.openal) example code and problem loading .wav files A: gambas-user@lists.sourceforge.net Data: Venerdì 21 agosto 2015, 06:39 Okay Benoît, you can take me off your list of people to kill now that I've finally gotten around to implementing OpenAL. :) The documentation online is pretty spartan, with much of it being outdated, but I still managed to set things up reasonably well to play a sine wave at a specified frequency and I think I've found the function to load a .wav file into an audio buffer in order to play it.

If OpenAL support it however, the library might need to be added as a dependency during compilation. -- Kevin Fishburne Eight Virtues www: http://sales.eightvirtues.com e-mail: sa...@eightvirtues.com phone: (770) 853-6271 -- ___ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user -- ___ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user
[Gambas-user] R: OpenAL (gb.openal) example code and problem loading .wav files
Hello Kevin, you did a good work. Well, in your code I replaced 'setting up listener' code with this: ' Set up listener. Al.Listenerfv(Al.POSITION, [0, 0, 0]) Al.Listenerfv(Al.VELOCITY, [0, 0, 0]) Al.Listenerfv(Al.ORIENTATION, [0, 0, -1]) and the wav file plays (but NOT sine wave and wav file together ...I do not know if you want it also). I suggest you insert this: Free(DataPointer) after Close #Mem Regards vuott Ven 21/8/15, Kevin Fishburne kevinfishbu...@eightvirtues.com ha scritto: Oggetto: [Gambas-user] OpenAL (gb.openal) example code and problem loading .wav files A: gambas-user@lists.sourceforge.net Data: Venerdì 21 agosto 2015, 06:39 Okay Benoît, you can take me off your list of people to kill now that I've finally gotten around to implementing OpenAL. :) The documentation online is pretty spartan, with much of it being outdated, but I still managed to set things up reasonably well to play a sine wave at a specified frequency and I think I've found the function to load a .wav file into an audio buffer in order to play it.
