* Don't enable NFC for a 0 reference delayChris Robinson2017-05-141-1/+1
|
* Update ChangeLog for AL_SOFT_source_spatializeChris Robinson2017-05-131-2/+4
|
* Update a couple comments about the reverb modulationChris Robinson2017-05-131-12/+13
|
* Replace 4 separate all-passes with one vector all-passChris Robinson2017-05-131-53/+47
| | | | | | Each 4 related all-passes now share a structure with one delay line, which uses an interleaved sample history. Also fixes some potential rounding problems for delay lines with interleaved samples.
* Apply reverb modulation to the late feedback linesChris Robinson2017-05-121-104/+71
| | | | | | | | This seems to be more in-line with the intended behavior, to allow build-up and overlap within the reverb decay, rather than a pitch-shift on input. Unfortunately there's no readily available implementation of this reverb model that includes modulation to compare with, so a low depth coefficient is used to keep it very subtle.
* Remove the 0.5 gain on the reverb outputChris Robinson2017-05-111-6/+2
| | | | | Turns out to be unnecessary, as it reduced the volume below what other reverb implementations provide with the same presets.
* Restore the previous reverb B2A and A2B matricesChris Robinson2017-05-111-12/+12
| | | | Also, untranspose the A2B matrix.
* Log whether the output limiter is enabled or disabledChris Robinson2017-05-111-0/+1
|
* Finalize AL_SOFT_source_spatializeChris Robinson2017-05-113-7/+7
|
* Update ALC_OUTPUT_LIMITER_SOFT to handle ALC_DONT_CARE_SOFTChris Robinson2017-05-111-4/+8
| | | | | Essentially just adding a comment about it. Since we default to on, the behavior already fit.
* Reduce LIMITER_VALUE_MAXChris Robinson2017-05-092-7/+13
| | | | | | The previous value couldn't actually be expressed as a float and got rounded up to the next whole number value, leaving the potential for an overrun in the squared sum.
* Store the output limiter values as fixed-point integersChris Robinson2017-05-082-13/+12
| | | | | This helps keep the squared sum stable over larger updates, also avoiding the need to keep recalculating it.
* Update reverb conversion matrices and output gainChris Robinson2017-05-081-10/+12
|
* Apply attenuation when downmixing multi-channel sounds for panningChris Robinson2017-05-071-10/+26

* Put the app name after filename in the window titleChris Robinson2017-05-071-1/+1
|
* Update AL_SOURCE_SPATIALIZE_SOFT valueChris Robinson2017-05-061-1/+1
| | | | | | Though it didn't strictly clash since it was for a different component (global state vs source property), 0x1213 was used by AL_RESAMPLER_NAME_SOFT. Probably best to avoid duplicate property values regardless.
* Include the Built-In HRTF names in alsoft-config when enabledChris Robinson2017-05-051-0/+5

|
* Rename Zero-Order Hold to NearestChris Robinson2017-05-031-1/+1
| | | | | | A bit of a misnomer now since "Nearest" implies rounding (i.e. when the sample offset is >= .5, it should pick the next sample being closer in time), but that adds unnecessary complications.
* Add a mixing function to blend HRIRsChris Robinson2017-05-037-27/+95
| | | | | | This is a bit more efficient than calling the normal HRTF mixing function twice, and helps solve the problem of the values generated from convolution not being consistent with the new HRIR.
* Add a slight bit of attenuation to the reverb outputChris Robinson2017-05-021-2/+4

|
* Reimplement bilinear interpolation between HRIRsChris Robinson2017-05-011-25/+82
| | | | | | Some data sets are just too sparse, having noticeably few measurements to properly handle slowly panning sources. Although not perfect, bilinearly interpolating the HRIR measurements improves the positional accuracy.
* Allow querying the output limiter stateChris Robinson2017-04-301-2/+12

* Start an extension to toggle the output limiterChris Robinson2017-04-302-5/+23
|
* Don't do more reverb samples than there are to fade.Chris Robinson2017-04-281-2/+6
| | | | This avoids having to clamp the fade value when incrementing it.
* Fade HRTF coefficients over 64 samples at mostChris Robinson2017-04-281-40/+69
| | | | | | This greatly improves HRTF performance since the dual-mix only applies to the 64-sample coefficient transition. So rather than doubling the full mix, it only doubles 64 samples out of the full mix.
* Combine mostly duplicate functionsChris Robinson2017-04-271-121/+50
|
* Properly update the delay line offsets when fading is doneChris Robinson2017-04-271-28/+44
