* Rename Ambisonics to Ambisonic in a couple placesChris Robinson2016-07-311-3/+3
|
* Remove DevFmtBFormat3D, which is covered by DevFmtAmbi1Chris Robinson2016-07-311-9/+0
|
* Add an option to specify the ambisonic output configurationChris Robinson2016-07-311-0/+15
|
* Rename ambisonic channel config values to be shorterChris Robinson2016-07-301-3/+3
|
* Add a stand-alone upsampler for higher-order ambisonic oputputChris Robinson2016-07-301-2/+5
|
* Add a config to output first-, second-, or third-order ambisonicsChris Robinson2016-07-291-4/+54
| | | | | | | | | Currently incomplete, as second- and third-order output will not correctly handle B-Format input buffers. A standalone up-sampler will be needed, similar to the high-quality decoder. Also, output is ACN ordering with SN3D normalization. A config option will eventually be provided to change this if desired.
* Don't try freeing the context in ReleaseThreadCtxChris Robinson2016-07-291-6/+6
| | | | | | | | | | | | Unfortunately on certain systems, the TLS callback is called in a restricted context, and isn't allowed to access certain messaging sub-systems. Such sub- systems may be used if the thread's context is freed, in turn freeing the device, which it tries to close. Ideally, the app shouldn't have tried to destroy a context while it was still current on a thread, or even leave a context current on a thread that's being destroyed,. So for now, release the context ref and print an ERR that it might be leaked.
* Remove broken autowah effect codeChris Robinson2016-07-261-7/+0
| | | | | It's been disabled forever, and I have no idea how to make it work properly. Better to just redo it when making something that works.
* Avoid function calls to get the HRTF sample rate and IR sizeChris Robinson2016-07-071-3/+3
|
* Remove the VirtOut buffer aliasChris Robinson2016-07-051-14/+10
|
* Use separate arrays for UIntMap keys and valuesChris Robinson2016-07-041-3/+3
|
* Rename MaxNoOfSources for consistencyChris Robinson2016-06-081-15/+15
|
* Add property queries to get the device latency with the clockChris Robinson2016-06-031-11/+32
|
* Clean up a couple variable names and declarationsChris Robinson2016-05-301-4/+4
|
* Use a linked list for active effect slotsChris Robinson2016-05-291-7/+1
|
* Use a specific lock for the backend's stop/reset/play callsChris Robinson2016-05-271-30/+44
| | | | | This helps protect against the device changing unexpectedly from multiple threads, instead of using the global list/library lock.
* Properly pluralize some messagesChris Robinson2016-05-221-5/+10
|
* Improve locking for device attribute queriesChris Robinson2016-05-221-8/+28
| | | | | Avoids the backend device lock, instead using the list lock to prevent the device from changing while being queried, and adds some missing locks.
* Update the right effect state when the device is resetChris Robinson2016-05-171-2/+2
|
* Use floats for the listener transformsChris Robinson2016-05-161-5/+5
|
* Avoid separate updates to sources that should apply togetherChris Robinson2016-05-151-0/+2
|
* Allocate context storage before starting/resetting the deviceChris Robinson2016-05-151-19/+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 updatedChris Robinson2016-05-151-2/+2
| | | | | 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 sourcesChris Robinson2016-05-141-48/+17
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Avoid updating the effect state object if it's not changedChris Robinson2016-05-121-12/+12
|
* Provide (mostly) lockless updates for effect slotsChris Robinson2016-05-121-31/+25
| | | | | | | | | | | | | | | | | 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 propertiesChris Robinson2016-05-111-4/+31
| | | | | | | | | | | 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 offsetChris Robinson2016-05-091-1/+1
|
* Find a valid source buffer before updating the voiceChris Robinson2016-05-091-3/+14
|
* Store more "active" listener and context properties separatelyChris Robinson2016-05-091-0/+5
| | | | | This helps ensure async listener/context property changes affect all playing sources at the same time.
* Don't crash when there's no backend to probeChris Robinson2016-04-301-2/+7
|
* Start AL_SOFT_buffer_samples2 as a replacement for AL_SOFT_buffer_samplesChris Robinson2016-04-251-8/+22
|
* Add support for AL_EXT_SOURCE_RADIUSChris Robinson2016-04-251-4/+6
|
* Drop support for AL_SOFT_buffer_samples and AL_SOFT_buffer_sub_dataChris Robinson2016-04-241-12/+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.

* Rename the BFormat channels to AuxChris Robinson2016-03-161-4/+4
|
* Add config options to enable the hq ambisonic decoderChris Robinson2016-03-161-1/+12
|
* Add a dual-band ambisonic decoderChris Robinson2016-03-151-6/+11
| | | | | | | | | | This uses a virtual B-Format buffer for mixing, and then uses a dual-band decoder for improved positional quality. This currently only works with first- order output since first-order input (from the AL_EXT_BFROMAT extension) would not sound correct when fed through a second- or third-order decoder. This also does not currently implement near-field compensation since near-field rendering effects are not implemented.
