* | Improve reverb panning gains for "3D" output. | Chris Robinson | 2016-05-17 | 1 | -8/+8 |
| | |||||
* | Ignore the listening angle for the wet path sound cones | Chris Robinson | 2016-05-16 | 1 | -32/+51 |
| | | | | | | | Since the wet path is essentially the room response to a sound, the direction of the sound to the listener doesn't change the amount of energy the room receives. Instead, the surface area defined by the cones dictate the volume the room gets for the sound. | ||||
* | Use floats for the listener transforms | Chris Robinson | 2016-05-16 | 2 | -66/+28 |

* | Allocate context storage before starting/resetting the device | Chris Robinson | 2016-05-15 | 1 | -19/+23 |
| | | | | | In case allocation fails, we don't have to worry about the playing status of the backend. | ||||
* | Avoid using a flag to specify if the effect state needs to be updated | Chris Robinson | 2016-05-15 | 2 | -6/+10 |
| | | | | | This fixes a potential missed state change if an update with a new state got replaced with one that doesn't. | ||||
* | Provide asynchronous property updates for sources | Chris Robinson | 2016-05-14 | 3 | -181/+153 |
| | | | | | | | | | | | | | | | | | | | | | | | | | This necessitates a change in how source updates are handled. Rather than just being able to update sources when a dependent object state is changed (e.g. a listener gain change), now all source updates must be proactively provided. Consequently, apps that do not utilize any deferring (AL_SOFT_defer_updates or alcSuspendContext/alcProcessContext) may utilize more CPU since it'll be filling out more update containers for the mixer thread to use. The upside is that there's less blocking between the app's calling thread and the mixer thread, particularly for vectors and other multi-value properties (filters and sends). Deferring behavior when used is also improved, since updates that shouldn't be applied yet are simply not provided. And when they are provided, the mixer doesn't have to ignore them, meaning the actual deferring of a context doesn't have to synchrnously force an update -- the process call will send any pending updates, which the mixer will apply even if another deferral occurs before the mixer runs, because it'll still be there waiting on the next mixer invocation. There is one slight bug introduced by this commit. When a listener change is made, or changes to multiple sources while updates are being deferred, it is possible for the mixer to run while the sources are prepping their updates, causing some of the source updates to be seen before the other. This will be fixed in short order. | ||||

* | Call the effect state update method after "returning" the container object. | Chris Robinson | 2016-05-12 | 1 | -2/+2 |
| | |||||
* | Avoid updating the effect state object if it's not changed | Chris Robinson | 2016-05-12 | 2 | -20/+19 |

* | Provide (mostly) lockless updates for effect slots | Chris Robinson | 2016-05-12 | 13 | -132/+177 |
| | | | | | | | | | | | | | | | | | Similar to the listener, separate containers are provided atomically for the mixer thread to apply updates without needing to block, and a free-list is used to reuse container objects. A couple things to note. First, the lock is still used when the effect state's deviceUpdate method is called to prevent asynchronous calls to reset the device from interfering. This can be fixed by using the list lock in ALc.c instead. Secondly, old effect states aren't immediately deleted when the effect type changes (the actual type, not just its properties). This is because the mixer thread is intended to be real-time safe, and so can't be freeing anything. They are cleared away when updates reuse the container they were kept in, and they don't incur any extra processing cost, but there may be cases where the memory is kept around until the effect slot is deleted. | ||||
* | Use a lockless method for updating listener and context properties | Chris Robinson | 2016-05-11 | 2 | -22/+71 |
| | | | | | | | | | | | This uses a separate container to provide the relevant properties to the internal update method, using atomic pointer swaps. A free-list is used to avoid having too many individual containers. This allows the mixer to update the internal listener properties without requiring the lock to protect against async updates. It also allows concurrent read access to the user-facing property values, even the multi-value ones (e.g. the vectors). | ||||
* | Use the source's offset type to determine if there's an offset | Chris Robinson | 2016-05-09 | 1 | -1/+1 |

* | Store more "active" listener and context properties separately | Chris Robinson | 2016-05-09 | 2 | -11/+25 |
| | | | | | This helps ensure async listener/context property changes affect all playing sources at the same time. | ||||

* | Drop support for AL_SOFT_buffer_samples and AL_SOFT_buffer_sub_data | Chris Robinson | 2016-04-24 | 1 | -12/+3 |
| | | | | | | Unfortunately they conflict with AL_EXT_SOURCE_RADIUS, as AL_SOURCE_RADIUS and AL_BYTE_RW_OFFSETS_SOFT share the same source property value. A replacement for AL_SOFT_buffer_samples will eventually be made. | ||||

| | |||||
* | Don't look up the dry buffer's FrontCenter in the Dedicated effect | Chris Robinson | 2016-04-16 | 1 | -8/+4 |
| | | | | | | The real FrontCenter output is used if it exists, and if it doesn't, it's unlikely the dry buffer will have it (and even if it does, it won't be any better than panning). | ||||

| | | | | | | Instead of looping over all the coefficients for each channel with multiplies, when we know only one will have a non-0 factor for ambisonic mixing buffers, just index the one with a non-0 factor. | ||||
