| | Stephen Baker | Using the 'convention' of an argument of zero turns something off is ugly for large applications because you can't globally enable or disable something without touching a bazillion lines of code. OpenGL had this right. | Pending |
| | Stephen Baker | Again, large programs need to be able to save current state - do something weird for a while - then restore the old state with absolute certainty. You might argue that you can do this in the application - but that's nasty to maintain in the presence of extensions to the underlying API...you can't manually save and restore state if new state items appear in extensions. | Pending |
| | Stephen Baker | alPushMatrix/alPopMatrix/alLoadMatrix, etc...and a way to position sources using said matrices. This would make integration with OpenGL applications *MUCH* simpler. | Pending |
| | Stephen Baker | I'd like to see an option to have source velocities be deduced automatically from consecutive source positions - given a global 'time step' specified by the application. I can see how not every application would want this - but for those that do, this would be a huge simplification. | Approved |

| | Stephen Baker | The idea is that an envelope (in OpenAL terms) would be a short, and typically very low frequency (1Hz to 5Hz maybe) alBuffer. An envelope could be attached to an alSource to modulate one of it's properties. The most obvious being it's pitch and volume. So you'd add just one extra call to the alSource API -- alSourceEnvelope (ALuint source, ALenum envelope_type, ALuint envelopeBuffer). Envelope_type would be either AL_ENVELOPE_PITCH or AL_ENVELOPE_GAIN. The idea is basically simple - as the main alBuffer is replayed, so are any envelope buffers - with the result of them modifying the alSource's parameters on-the-fly. | Pending |

| | Eugene Stets | That is highly awaited features for most of developers. It's very important point to take everything from the hardware acceleration and to show it's advantages like extremely low latency for example. X-RAM is the best idea i seen so far but it's incomplete without Play/Stop callbacks. We need the swiss knife API so in long term the community can make any "ALchemy" with ease. | Pending |
| | | OpenAL library implementation could compensate for low count of sources implemented in hardware, by "swapping" the sources into inactive list, swapping out sources most distant from the listener, to compensate for limit of simultaneous active sources.
The sources would still advance current position, playback, queve new buffers, etc.. but would not output any samples (null output) until they come back into the listener active range or number of sources decreases under the maximum limit.
| Pending |
| | | OpenAL should have an api to retrieve the precise hardware timer data, this would improve precision of timing simulation in audio system related events and for other related usage.
| Pending |
| | Michael Heilmann | The VBO/PBO system of OpenGL separates the buffer data from its interpretation and offers a very flexible system of manipulating the data in the buffers. OpenAL should employ a similar concept. | Pending |
| | Patrick Dugan | OpenAL should allow for callbacks to perform CPU processing of audio buffers. The ability to add in your own effects into the signal path is common in many other audio engines (XAudio2, FMOD, Wwise, etc). I believe this would provide alot of value for developers using OpenAL. | Pending |
| | Raks | Can you please add 6.1ch support to the next driver update for vista 64, we all would appreciate if this could be done since most of us still use 6.1ch speaker + amp systems.
We would be grateful if you could add 6.1ch support to the driver and console manager and any other relating pieces of software for games, music and apps, much appreciated | Pending |
| | Zbigniew L. | Please provide hardware accelerated OpenAL (with EAX5 extensions) library for Linux. For example OpenAL for X-FI on Linux could be good reference start point for porting Windows games to Linux and creating fast sound processing applications. In Linux good OpenAL library could be used for sound scientific applications in a very same way as OpenGL is used now. | Pending |

| | JernejL | There is very large need for callbacks, such as when the AL_SOURCE_STATE changes, using this i can perform various custom real-time buffer "stitching", for example in some cases i don't want to queue buffers early, but queue them manually when they are needed, this is important for example where you have a source which consists of several buffers and only one of them is looping.

| | Dan O. | This would be great to have in conjunction with Play/Stop Callbacks. It would let you rest easy until OpenAL requests more data which you could send during the callback. this would make streaming in a complex application much cleaner to implement. And would remove the need for silly extra threads just to watch a handful of alSources. | Pending |
| | emacinnes | Being able to automatically handle stereo (and quad) sound in 3D space, via multiple positions.
The GL equivalent here is multi-texturing, by allowing position indexes, with index 1 as being the "default" to represent where each part of the channel should go.
Real world implementation here would be to simulate a character walking into a bar or a disco nightclub setting with surround sound, being able to position the speakers independently.
If the multi-positioning isn't enabled, to just flatten the audio into mono before playback, if 3D positioning is enabled for non-mono audio. | Pending |
| | Nils | Though OpenAL can play multichannel sound data, it only allows to output them to analogue outputs of a soundcard, digital outputs will only get a stereo downmix because a multichannel digital output would require AC-3 encoding.
A realtime AC-3 encoder would be a nice addition to be able to have 5.1 sound sent to a A/V receiver for any program that makes use of OpenAL.

| | Victor G. | When playing video, it's necessary to synchronize video and audio streams. This involves keeping a timestamp of an audio buffer being played until just before or just after it's been played. Since audio streams typically come in packets of unpredictable length, it's not possible to know the exact timestamp of an unqueued buffer by pushing decoded buffers and popping played buffers from a fixed-sized queue. The only possible solution involves pushing longer, fixed-sized buffers into a short (2 or 3 buffers) queue, which is far more complex and not even possible if the decoded buffers have variable sample rates or channel counts.
The ability to add arbitrary user data to a buffer would greatly simplify the design of client applications in these situations. | Pending |

| | LR | The alSourcef AL_GAIN don't let to use a Volume factor >1 even when changing the min/max range values of the output factor. So, it is important for porting Direct3D applications to have the possibility to use a volume >1. Some sounds are recorded very slowly and it is not possible to re-sample all files whereas OpenAL can easily allow Volume range >1. | Pending |
