* Increase the max pitch to 255Chris Robinson2015-09-261-1/+1
| | | | | | | Note that this is the multiple above the device sample rate, rather than the source property limit. It could theoretically be increased to 511 by testing against UINT_MAX instead of INT_MAX, since the increment and positions are using unsigned integers. I'm just being paranoid about overflows.
* Use a single enum list for source propertiesChris Robinson2015-09-221-346/+416
|
* Avoid a potential race condition with NewThunkEntryChris Robinson2015-09-211-0/+13
| | | | | | It's possible for another invocation to increase the array size in between the ReadUnlock and WriteLock calls, causing the 'i' index to refer to a taken entry.
* Handle up to 6 values with alSourcedvSOFT and alGetSourcefvChris Robinson2015-09-211-4/+4

* Allow for device-specific config valuesChris Robinson2015-08-282-9/+9
|
* Use ACN ordering for ambisonics coefficients arraysChris Robinson2015-08-281-4/+4
| | | | | | Note that it still uses FuMa scalings internally. Coefficients loaded from config files specify if they're FuMa (in both ordering and scaling) or N3D, and will get reordered or rescaled as needed.
* Don't explicitly store first-order coefficientsChris Robinson2015-08-181-5/+3
| | | | | | | It seems a simple scaling on the coefficients will allow first-order content to work with second- and third-order coefficients, although obviously not with any improved locality. That may be something to look into for the future, but this is good enough for now.
* Allow specifying ALC_DONT_CARE_SOFT for ALC_HRTF_SOFTChris Robinson2015-07-061-2/+8
| | | | | ALC_FALSE now indicates explicitly no HRTF mixing, while ALC_DONT_CARE_SOFT is autodetect.
* Update a couple commentsChris Robinson2015-07-041-1/+1

* Add a macro to simplify allocating and constructing an objectChris Robinson2015-05-181-0/+12

* Convert the solaris backend to the new APIChris Robinson2015-05-171-3/+0
|
* Add a method to reset the deviceChris Robinson2015-05-161-0/+4
| | | | | | | This basically acts as if the app created a new context with the specified attributes (causing the device to reset with new parameters), then immediately delete it. Existing contexts remain undisturbed, except for a temporary pause while the device output is reconfigured.
* Add a few more HRTF status valuesChris Robinson2015-05-161-1/+4
| | | | | | | | | DISABLED - Generic disabled status ENABLED - Generic enabled status DENIED - Not allowed (user has configured HRTF to be off) REQUIRED - Forced (user has forced HRTF to be used) HEADPHONES_DETECTED - Enabled because headphones were detected UNSUPPORTED_FORMAT - Device format is not compatible with available filters
* Add an HRTF status queryChris Robinson2015-05-151-0/+5
| | | | | This can report the status of HRTF, specifying if it's enabled or not and why (currently only reports unsupported formats, but this may be extended).
* Add an option for "basic" HRTF renderingChris Robinson2015-02-111-0/+8
| | | | | | | | | | | | | | | | | This method is intended to help development by easily testing the quality of the B-Format encode and B-Format-to-HRTF decode. When used with HRTF, all sources are renderer using the virtual B-Format output, rather than just B-Format sources. Despite the CPU cost savings (only four channels need to be filtered with HRTF, while sources all render normally), the spatial acuity offered by the B-Format output is pretty poor since it's only first-order ambisonics, so "full" HRTF rendering is definitely preferred. It's /possible/ for some systems to be edge cases that prefer the CPU cost savings provided by basic over the sharper localization provided by full, and you do still get 3D positional cues, but this is unlikely to be an actual use- case in practice.

* Add a lockless ringbufferChris Robinson2014-12-231-0/+19
| | | | | | Largely copied from JACK, it's extended to work with user-specified element sizes instead of bytes. This is necessary to be able to work with 6- and 7- channel output modes.

|
* Partially revert "Use a different method for HRTF mixing"Chris Robinson2014-11-233-1/+22
| | | | | | | | | | | | The sound localization with virtual channel mixing was just too poor, so while it's more costly to do per-source HRTF mixing, it's unavoidable if you want good localization. This is only partially reverted because having the virtual channel is still beneficial, particularly with B-Format rendering and effect mixing which otherwise skip HRTF processing. As before, the number of virtual channels can potentially be customized, specifying more or less channels depending on the system's needs.
* Attempt to use BS2B when using headphones without HRTFChris Robinson2014-11-221-1/+0
|
* Rework HRTF decision logicChris Robinson2014-11-221-0/+1
| | | | | | This way takes into account a new stereo-mode config option, which when set to "headphones" will default to using HRTF. Eventually the device will also be able to specify if headphones are being used.
* Remove an unused macroChris Robinson2014-11-221-3/+0

|
* Use a different method for HRTF mixingChris Robinson2014-11-223-41/+35
| | | | | | | | | | | | | | | | | | | | | | | This new method mixes sources normally into a 14-channel buffer with the channels placed all around the listener. HRTF is then applied to the channels given their positions and written to a 2-channel buffer, which gets written out to the device. This method has the benefit that HRTF processing becomes more scalable. The costly HRTF filters are applied to the 14-channel buffer after the mix is done, turning it into a post-process with a fixed overhead. Mixing sources is done with normal non-HRTF methods, so increasing the number of playing sources only incurs normal mixing costs. Another benefit is that it improves B-Format playback since the soundfield gets mixed into speakers covering all three dimensions, which then get filtered based on their locations. The main downside to this is that the spatial resolution of the HRTF dataset does not play a big role anymore. However, the hope is that with ambisonics- based panning, the perceptual position of panned sounds will still be good. It is also an option to increase the number of virtual channels for systems that can handle it, or maybe even decrease it for weaker systems.
