Re: [Audyssey] To Developers: Switching from DirectSound to OpenAL Soft
Hi Shaun, The delay / reverb and other effects are actually system-specific and not a part of OpenAL. OpenAL does not have these by default, so it relies on the particular system on which it is running to take care of this. So any issues you may be seeing are not with OpenAL itself but with the way the digital signal processing is implemented on the platform / machine it is being run on.

Re: [Audyssey] To Developers: Switching from DirectSound to OpenAL Soft
No but the people I work with for the deathmatch series do use fsl on purebasic which does have open al intigrated. The environmental and other effects do have a few echo issues, but over all are ok. I am not sure about anything else which is not purebasic. At 06:20 a.m. 14/12/2013, you wrote: Hi developers, I recently decided to switch from DirectSound to OpenAL Soft.

If you've used both DirectSound and OpenAL Soft you can probably give me the best information about what switching entails.

OpenAL Soft also suggests installing OpenAL from Creative Labs first and then installing OpenAL Soft side by side to get some possible extra driver benefit. Does this matter in the real world? I heard that Creative Labs stopped updating OpenAL ages ago, which is why I wonder about the actual benefit. Again, I'm looking for help from people with actual OpenAL experience.

Re: [Audyssey] To Developers: Switching from DirectSound to OpenAL Soft
Thanks Cara and Willem. This is very helpful. It is nice to have a library to look at for parsing sound files. I'm also quite glad to hear I can play sounds and music non-positionally. So I can set even a mono sound's source to be stereo and make it non-positional, right Cara? I think OpenAL and OpenAL Soft are 95% the same. You can even rename the OpenAL Soft dll to OpenAL32.dll and use it as a drop in replacement for OpenAL. The only differences I read about were HRTF support and some extra filter support. If you think of any other useful tidbits, I'm all ears, smile.

Re: [Audyssey] To Developers: Switching from DirectSound to OpenAL Soft
Hi Ian, I use OpenAL rather than OpenAL Soft so hopefully this will help. Yes, you can play music in the same context as positional audio simply by defining the source as stereo rather than mono. When you do this, the source automatically becomes non-positional so you can use it to play music etc, along with your positioned mono sources. To your second point about positioning stereo sounds, I'm not sure about OpenAL Soft but in OpenAL you would need to play the left and right channels of your sound independently using two sources. This way you can position a stereo sound in 3D space. Hope this helps.

In my current setup I use DirectSound for 3D sounds and DirectX.AudioVideoPlayback for all other sounds. It seems that OpenAL leaves parsing the sound files up to the developer. I do have code for parsing a .wav file, but it would also be nice to use mp3 and ogg vorbis for the stereo sounds and music. Is there a recommended library for getting this benefit? I am using C#, but in general popular C libraries have C# wrappers that I can use. Being able to play stereo sounds and music in OpenAL would be one step closer to cross platform. I also saw a comment in one of the text files in OpenAL Soft that indicated that it could play 3D mono and multi-channel sounds. Can it actually play multi-channel audio in 3D space? Assuming I set the position of the left track and the position of the right track in 3D space? The statement they made could be read as meaning that both mono and multi-channel sounds could be played in 3D. Or maybe the 3D adjective applied only to the mono sounds.

Re: [Audyssey] To Developers: Switching from DirectSound to OpenAL Soft
Hello Ian. I'm a bit rushed timewise, but I'll mention a few things to get started. For loading of other formats look at alure. HRTF is enabled automatically. If you have 3d sound support all you need to do to pan the sound is change the x coordinate of the source. As far as I know only mono sounds can be positioned in a 3d world, because a stereo source contains inherrant positional information which a mono source does not. Maybe you should ask this question on the developers list too.

[Audyssey] To Developers: Switching from DirectSound to OpenAL Soft
Hi developers, I recently decided to switch from DirectSound to OpenAL Soft. I did this for 2 reasons: 1 Because OpenALSoft has built in HRTF support. 2 Because OpenAL Soft is cross platform. Right after I got the simplest of demo applications playing a simple sound I got terribly sick and have been in bed for the past few days. So as I wait until I am well enough to continue working on it I thought I'd ask if any other developers have advice on the subject. If you've used both DirectSound and OpenAL Soft you can probably give me the best information about what switching entails. But even if you've only used Open AL Soft I think there is a lot I could learn from you. Basically any advice about quirks, gotchas, and awesome benefits are appreciated. Also, it's my impression that the HRTF support is automatic and I don't need to enable it in code. Is this correct? Has anyone had real experience with the OpenAL Soft HRTF specifically? Is it any good? Is anyone using the original OpenAL instead of OpenAL Soft for 3D games? If so, why? OpenAL Soft also suggests installing OpenAL from Creative Labs first and then installing OpenAL Soft side by side to get some possible extra driver benefit. Does this matter in the real world? I heard that Creative Labs stopped updating OpenAL ages ago, which is why I wonder about the actual benefit. Again, I'm looking for help from people with actual OpenAL experience. Thanks for any help you can give.
