* Fixes for embedded HRTFs on OSXChris Robinson2016-11-112-8/+11
| | | | | | | | Use an empty source file to build a stub object file, instead of /dev/null. Use _mh_dylib_header to retrieve the data on 10.7+, instead of _mh_execute_header. And shorten the names to fit in the 16-character limit. Thanks to Anna Cheremnykh for the fixes!

* | Rebalance the frequencies for B-Format HRTF coefficientsChris Robinson2016-11-011-14/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original pseudo-inverse method that generated the LF matrix expects the high frequencies to be scaled up by ~2.645751 over the low frequencies (or sqrt(7), ~8.45dB). However, the AllRAD method used to generate the HF matrix produced a matrix that was only scaled up by 1.46551981258 (based on the average of the W coefficients). Previously, the LF matrix was scaled down by sqrt(7), as the difference specified in the pseudo-inverse results. This failed to account for the increase already present in the HF matrix, so now the LF matrix is scaled down by the remaining difference between the expected scaling and the scaling already present in the HF matrix (sqrt(7) / 1.46551981258 = 1.80533302205, or roughly 5.13dB, where the reciprocal is 0.553914423 for -5.13 dB).

* Don't interpolate between nearest HRIRsChris Robinson2016-10-093-80/+43
| | | | | | | | It still fades between HRIRs when it changes, but now it selects the nearest one instead of blending the nearest four. Due to the minimum-phase nature of the HRIRs, interpolating between delays lead to some oddities which are exasperated by the fading (and the fading is needed to avoid clicks and pops, and smooth out changes).

* Enhance reverb using B-Format processingChris Robinson2016-10-031-405/+386
| | | | | | | | | | | | Technically it uses A-Format processing from the B-Format input and output. But this attempts to provide better spatial definition to the reverberation so that it can be used in a more generic fashion, allowing it to be decoded as any other B-Format signal to whatever output is needed, and also allowing for a bit of height information when the output is capable of such. There may still be some kinks to work out, such as properly decorrelating the early reflection taps and tweaking the late reverb density. But it seems to be a good enough start.
* Finalize AL_SOFT_gain_clamp_exChris Robinson2016-10-033-6/+6
|
* Update the ambisonic coefficients for HRTFChris Robinson2016-09-261-15/+15
| | | | | | | This uses an AllRAD-derived decoder matrix for the high frequencies, which seems to improve positioning response. It also switches back to dual-band. The low frequencies appear to be unexpectedly quiet by comparison, but it's not that bad and can be tweaked later.
* Add a volume-adjust config option to adjust the source output volumeChris Robinson2016-09-245-6/+32
| | | | | | | | | Designed for apps that either don't change the listener's AL_GAIN, or don't allow the listener's AL_GAIN to go above 1. This allows the volume to still be increased further than such apps may allow, if users find it too quiet. Be aware that increasing this can easily cause clipping. The gain limit reported by AL_GAIN_LIMIT_SOFT is also affected by this.
