* Remove the SAFE_CONST macroChris Robinson2018-01-141-10/+9
| | | | | Seems compilers are now allowing a pointer-to-type-array to implicitly convert to pointer-to-const-type-array.

* Remove the sinc4 tableChris Robinson2018-01-071-5/+0
|
* Replace the sinc4 resampler with cubicChris Robinson2018-01-071-2/+0
| | | | | | | Turns out the C version of the cubic resampler is just slightly faster than even the SSE3 version of the FIR4 resampler. This is likely due to not using a 64KB random-access lookup table along with unaligned loads, both offseting the gains from SSE.
* Allow storing multiple buffers in a ALbufferlistitemChris Robinson2017-12-151-1/+1
| | | | | | | | | | | | | | | 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.
* Re-update effect slots when context properties changeChris Robinson2017-09-271-54/+41
| | | | | Also keep all free property update structs together in the context instead of per-object.
* Update the context state properties separatelyChris Robinson2017-09-271-20/+32
| | | | | | | | | | | | | 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.
* Add an option to ignore the app's speed of sound for reverb decayChris Robinson2017-09-221-2/+10
|
* Use the app-specified speed of sound for reverb decayChris Robinson2017-09-211-1/+2
| | | | | Specifically, the initial reverb decay as determined by the source distance, and the reverb decayhf limit from air absorption.
* Pass the context to the auxiliary effect update methodChris Robinson2017-09-211-3/+3
|
* Automatically generate the bsinc table when buildingChris Robinson2017-08-281-1/+1
| | | | | This makes bsincgen a native tool like bin2h, so it can run automatically when compiling.
* Add a higher quality bsinc resampler using 24 sample pointsChris Robinson2017-08-271-9/+14
| | | | | | | 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 Robinson2017-08-251-6/+6
|
* Meters per unit can't be 0Chris Robinson2017-08-211-2/+2

* Properly clear the extra ChannelsPerOrder entriesChris Robinson2017-08-191-1/+1
|
* Pass the filter entry to apply to resample_fir4Chris Robinson2017-08-181-3/+2
|
* Store the sinc4 table in the filter stateChris Robinson2017-08-161-3/+11
| | | | Also rename the resampler functions to remove the unnecessary '32' token.
* Simplify bsinc filter storage in the filter stateChris Robinson2017-08-161-12/+3
| | | | | | | 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.
* Make the bsinc table layout more efficientChris Robinson2017-08-161-4/+4
| | | | | | | | | | | | | | | | The old layout separated filters, scale deltas, phase deltas, and scale phase deltas into separate segments that each contained a numbers of scale and phase entries, Since processing a sample needed a filter and one of each delta entry relating to a particular scale and phase, the memory needed would be spread across the whole table. And since subsequent samples would use a different phase, it would jump around the table a whole lot as well. The new layout packs the data in a way more consistent with its use. The filters, scale deltas, phase deltas, and scale phase deltas are interleaved, such that for a particular scale and phase, the filter and delta entries used are contiguous. And the phase entries for a particular scale are kept together, so the ~500 to ~1000 samples processed per source update stay within the same 3KB to 6KB area of the 70+KB table, which is much more cache friendly.
