* Use a different method for HRTF mixingChris Robinson2014-11-221-4/+4
| | | | | | | | | | | | | | | | | | | | | | | 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.

* Use the UNUSED macro instead of a void castChris Robinson2014-07-191-2/+1

* Stop trying to read samples if there was an errorChris Robinson2014-07-191-1/+1

* Trace when a soundfont buffer goes unusedChris Robinson2014-07-191-0/+3
|
* Keep existing presets when loading in a new soundfontChris Robinson2014-07-191-3/+5
| | | | | | Note that alLoadSoundfontSOFT doesn't currently allow using a soundfont with existing presets. This is for being able to load and stack multiple soundfonts for the default soundfont.

* Load soundfont samples into an ALbufferChris Robinson2014-06-292-8/+21
| | | | | Also remove ALsoundfont's now-unneeded sample storage functions and struct fields.
* Store and use an ALbuffer for samples in an ALfontsoundChris Robinson2014-06-291-3/+5
| | | | | | | | The fontsound still maintains its own start, end, and loop offsets, so that the same buffer may be shared between multiple/all fontsounds. Ideally a single buffer should be used for all fontsounds to avoid memory fragmentation and help CPU caching, although higher quality soundfonts may need more memory than a single buffer can hold.
* Add a cast to silence an MSVC warningChris Robinson2014-05-041-2/+3

* Trace skipped info sub-chunksChris Robinson2014-05-041-0/+2

* Use ALuint for the amount to skipChris Robinson2014-05-041-1/+1
|
* Add a GCC-specific STATIC_UPCAST macro that checks the object typeChris Robinson2014-04-191-1/+1
| | | | | The check is compile time, and is functionally identical to the old/alternate version.
* Add a VECTOR_INSERT method to insert a range of elements at onceChris Robinson2014-04-091-10/+6

* Add some integer casts, and a range checkChris Robinson2014-03-231-1/+1
|
* Add a stub 'soft' MIDI synth handlerChris Robinson2014-03-222-0/+143
| | | | | Eventually this one will be used to handle MIDI internally, using our own mixers and resamplers.
* Use a void* for the MidiSynth Delete method paramChris Robinson2014-03-223-18/+9

* Slightly shorten a long lineChris Robinson2014-02-021-1/+1
|
* Rework MIDI clock timingChris Robinson2014-02-024-123/+62
| | | | | | It's best to avoid using doubles in the mixer since the FPU's set to single- precision mode. The new clock timing is similar to the device clock timing, and should hopefully be less prone to drift caused by fp rounding errors.
* Use nanosecond resolution for MIDIChris Robinson2014-02-011-2/+2
| | | | | This makes the MIDI clock use the same resolution as the device clock and source latency and the device clock.
* Properly fill the SF2 sample buffer on big endianChris Robinson2014-02-011-1/+1
