* Fix the lfo_offset for a 0-rate flangerChris Robinson2017-12-191-1/+1

* Fade gains in the chorus and flanger outputChris Robinson2017-12-192-16/+20
|
* Use a single delay line for chorus feedback on a fixed tapChris Robinson2017-12-182-92/+118
| | | | | | The outputs themselves use a variale-delay tap, but using a separate fixed- delay tap on the feedback helps improve the perceived "wobble" with sustained notes. This also applies to the flanger effect.
* Apply chorus and flanger feedback on the tapped re-feedChris Robinson2017-12-172-6/+6

* Mix multiple buffers in each buffer list itemChris Robinson2017-12-161-64/+112
| | | | Basically now this just relies on being able to specify composited buffers.
* Pre-clear the source temp buffer and accumulate into itChris Robinson2017-12-161-18/+7
|
* Rename SrcDataSize to be less confusingChris Robinson2017-12-161-25/+23
|
* Allow storing multiple buffers in a ALbufferlistitemChris Robinson2017-12-152-4/+8
| | | | | | | | | | | | | | | This will be to allow buffer layering, multiple buffers of the same format and sample rate that are mixed together prior to resampling, filtering, and panning. This will allow composing sounds from individual components that can be swapped around on different invocations (e.g. layer SoundA and SoundB on one instance and SoundA and SoundC on a different instance for a slightly different sound, then just SoundA for a third instance, and so on). The longest buffer within the list item determines the length of the list item. More work needs to be done to fully support it, namely the ability to specity multiple buffers to layer for static and streaming sources. Also the behavior of loop points for layered static sources should be worked out. Should also consider allowing each layer to have a sample offset.
* Update flanger with the same changes as chorusChris Robinson2017-12-151-44/+55
|
* Use a separate LFO offset in the chorus effectChris Robinson2017-12-151-10/+19
| | | | | Given that the LFO range is not a power-of-two, it won't correctly wrap on overflow.
* Use linear interpolation for the chorus delay outputChris Robinson2017-12-151-37/+39
|
* It's getFactory that may be NULL, not its return value...Chris Robinson2017-11-261-3/+4

* Don't probe a NULL backend factoryChris Robinson2017-11-261-2/+2
|
* Properly initialize with the default distance modelChris Robinson2017-10-291-6/+3
|
* Enable NFC filters for HRTFChris Robinson2017-10-231-0/+2
| | | | Only applies to the Ambisonic mix (basic HRTF rendering, or B-Format buffers).
* Store the HRTF distance in the Hrtf handleChris Robinson2017-10-232-8/+13
|
* Update mhr format for 24-bit, multi-field, stereo measurementsChris Robinson2017-10-221-44/+83
| | | | | Currently only single field HRTFs are supported, but the format now allows up to 16.
* Add casts for assigning the SSE bsinc filter pointersChris Robinson2017-10-071-4/+4
|
* Avoid a separate function to query ambisonic mode supportChris Robinson2017-09-271-26/+10
| | | | | | Now FuMa and ACN channel orders are required, as are FuMa, SN3D, and N3D normalization schemes. An integer query (alcGetIntegerv) is added for the maximum ambisonic order.
* Re-update effect slots when context properties changeChris Robinson2017-09-272-78/+91
| | | | | Also keep all free property update structs together in the context instead of per-object.
* Don't update context and listener props unnecessarilyChris Robinson2017-09-271-2/+9
|
* Update the context state properties separatelyChris Robinson2017-09-272-34/+69
| | | | | | | | | | | | | The context state properties are less likely to change compared to the listener state, and future changes may prefer more infrequent updates to the context state. Note that this puts the MetersPerUnit in as a context state, even though it's handled through the listener functions. Considering the infrequency that it's updated at (generally set just once for the context's lifetime), it makes more sense to put it there than with the more frequently updated listener properties. The aforementioned future changes would also prefer MetersPerUnit to not be updated unnecessarily.
* Restore the original JACK message callback when possibleChris Robinson2017-09-231-1/+9

* | Use the app-specified speed of sound for reverb decayChris Robinson2017-09-212-5/+9
| | | | | | | | | | Specifically, the initial reverb decay as determined by the source distance, and the reverb decayhf limit from air absorption.

* Manually save and restore the FPU rounding mode on WindowsChris Robinson2017-09-191-0/+10
| | | | | | | Apparently there is a bug with at least MinGW-W64 where fegetenv and fesetenv do not properly save and restore the FPU rounding mode, resulting in the rounding mode remaining as round-to-zero after certain function calls. I do not know if this also affects MSVC, but better safe than sorry for now.
* Avoid some extraneous load callsChris Robinson2017-08-302-26/+23
| | | | | This likely doesn't change anything given a working optimizer, but it cleans up the code some.
* Automatically generate the bsinc table when buildingChris Robinson2017-08-282-6703/+1
| | | | | This makes bsincgen a native tool like bin2h, so it can run automatically when compiling.
* Ensure some macros have the correct sizeChris Robinson2017-08-281-0/+4
|
* Add a higher quality bsinc resampler using 24 sample pointsChris Robinson2017-08-274-11/+1319
| | | | | | | This improves the transition width, allowing more of the higher frequencies remain audible. It would be preferrable to have an upper limit of 32 points instead of 48, to reduce the overall table size and the CPU cost for down- sampling.
* Rename the bsinc resampler to bsinc12Chris Robinson2017-08-254-25/+26

* Constify some pointersChris Robinson2017-08-233-3/+3

* Properly clear the extra ChannelsPerOrder entriesChris Robinson2017-08-191-1/+1

* Pass the filter entry to apply to resample_fir4Chris Robinson2017-08-185-7/+6
|
* Keep bsinc filter quality more consistent between scalesChris Robinson2017-08-171-544/+544
| | | | | | | This generates the filters using the proper size and scale. The 'a' divisor should represent the +/- sample range (and thus be a whole number), with the number of sample points being double that. Increasing the filter size to a multiple of 4 (for SIMD) can be done by padding in 0s afterward.
* Correct the bsinc filter orderChris Robinson2017-08-171-963/+963
| | | | | | Despite the claim that it was an 11th order filter, the transition width was generated by specifying 12th order. A 12th order filter would need 14 sample points rather than the 12 it had.
* Make the sinc4 table staticChris Robinson2017-08-161-1/+1
|
* Store the sinc4 table in the filter stateChris Robinson2017-08-1610-85/+112
| | | | Also rename the resampler functions to remove the unnecessary '32' token.
* Simplify bsinc filter storage in the filter stateChris Robinson2017-08-164-24/+18
| | | | | | | Rather than storing individual pointers to filter, scale delta, phase delta, and scale phase delta entries, per phase index, the new table layout makes it trivial to access the per-phase filter and delta entries given the base offset and coefficient count.
