* Store the source's previous samples with the voiceChris Robinson2015-10-152-0/+5
| | | | | | This helps avoid different results when looping is toggled within a couple samples of the loop point, or when a processed buffer is removed while the source is only a couple samples into the next buffer.
* Replace the sinc6 resampler with sinc8, and make SSE versionsChris Robinson2015-10-111-4/+5
|
* Move the FIR4 from SSE2 to SSE3Chris Robinson2015-10-111-2/+3
| | | | | SSE3 can avoid the slow _MM_TRANSPOSE_PS4 call thanks to the inclusion of horizontal adds.
* Allow apps to request a specific HRTFChris Robinson2015-10-071-2/+3
|
* Use the enumerated HRTF list for selecting an HRTFChris Robinson2015-10-061-0/+1
| | | | Also report the proper specifier of the one currently in use.
* Enumerate and list HRTFs per-deviceChris Robinson2015-10-061-0/+1
|
* Add a function to get a list of data filesChris Robinson2015-10-031-0/+2
| | | | | | The method takes a marked-up filename (e.g. may include %r for a sample rate, %% for %, etc), and returns a vector of strings of found filenames that match. It will search the CWD, the local, and global data directories, in that order.
* Add methods to enumerate and query device HRTFsChris Robinson2015-10-031-0/+4
| | | | Currently just returns a dummy entry.
* Move the resampler stuff to mixer.c where it's usedChris Robinson2015-10-012-14/+0
|
* Implement a 6-point sinc-lanczos filterChris Robinson2015-09-292-2/+12
|
* Replace the cubic resampler with a 4-point sinc/lanczos filterChris Robinson2015-09-272-4/+4
|
* Don't keep selecting the mixer to useChris Robinson2015-09-272-3/+1
|
* 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.
* Get rid of ALCdevice_GetLatencyChris Robinson2015-09-211-1/+0
|
* Fix updating listener params when forcing updatesChris Robinson2015-09-181-0/+2
|
* Use sizeof T for the size of the object typeChris Robinson2015-09-151-5/+5
|
* Rename F_2PI to F_TAUChris Robinson2015-09-131-1/+1
|
* Set both BS2B parameters at onceChris Robinson2015-09-081-7/+4
|
* Don't store the HRTF request mode in the device flagsChris Robinson2015-09-051-8/+1
|
* Allow for device-specific config valuesChris Robinson2015-08-281-8/+8
|
* 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.
* Move HRTF params and state closer togetherChris Robinson2015-02-091-3/+3

* Add missing alignas to CubicLUT declarationChris Robinson2015-01-131-1/+1
|
* Remove some IN_IDE_PARSER usesChris Robinson2014-12-241-7/+0
|
* Remove some unnecessary restrict usesChris Robinson2014-12-241-7/+6
|
* 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.
* Use a macro for the record thread nameChris Robinson2014-12-211-0/+2
|
* Fix logging on WindowsChris Robinson2014-12-201-1/+1
|
* Use aluVector and aluMatrix in a couple more placesChris Robinson2014-12-161-1/+1
|
* Use aluVector in some more placesChris Robinson2014-12-162-5/+5
|
* Add explicit matrix and vector types to operate withChris Robinson2014-12-162-2/+41
|
* Use a lookup table to do cubic resamplingChris Robinson2014-12-151-9/+9

|
* Move the voice's last position and gain out of the Hrtf containerChris Robinson2014-11-241-2/+3
|
* Add a boolean to specify if a device is headphonesChris Robinson2014-11-231-0/+1
|
* Remove unused channel enumsChris Robinson2014-11-231-2/+0
|
* Remove the cube+diamond virtual layoutChris Robinson2014-11-231-1/+1
|
* Partially revert "Use a different method for HRTF mixing"Chris Robinson2014-11-232-1/+11
| | | | | | | | | | | | 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
