|
* Avoid calculating the filter coefficients multiple timesChris Robinson2017-05-211-24/+36
|
* Add a method to copy a filter's coefficientsChris Robinson2017-05-212-39/+6
|
* Avoid unnecessary doublesChris Robinson2017-05-211-2/+2
|
* Use a macro to specify the decay target gainChris Robinson2017-05-212-7/+7
|
* Use more correct doppler shift calculationsChris Robinson2017-05-201-11/+24
|
* Restore spec-defined cone behavior for auxiliary sendsChris Robinson2017-05-201-26/+23
|
* Apply more proper air absorption to the wet pathChris Robinson2017-05-191-21/+53
| | | | | | | | This properly accounts for the room rolloff factor for normal air absorption (which makes it none by default, like distance attenuation), and uses the reverb's decay time, decay hf ratio, decay hf limit, and room air absorption properties to calculate an initial hf decay with the WetGainAuto flag. This mirrors the behavior of the initial distance decay.
* Reorganize some code to have fewer temporariesChris Robinson2017-05-171-39/+34
|
* Add an env var to specify a default pulse deviceChris Robinson2017-05-161-0/+7
| | | | | Some apps don't allow selecting an audio device, and due to problems with KDE, PulseAudio isn't allowed to move the stream after being created by default.
* Reduce the main reverb filter gain limit to match the restChris Robinson2017-05-161-4/+4
|
* Limit the dry and wet path filter gains to -60dBChris Robinson2017-05-151-4/+4
|
* Improve distance-related absorption and decay attenuationChris Robinson2017-05-151-15/+14
|
* Make reverb delay line structs use interleaved floatsChris Robinson2017-05-151-68/+73
|
* Make the reverb's early and late feedback lines interleavedChris Robinson2017-05-141-42/+47
|
* Don't enable NFC for a 0 reference delayChris Robinson2017-05-141-1/+1
|
* 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 Robinson2017-05-111-1/+1
|
* 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 Robinson2017-05-091-6/+12
| | | | | | 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 Robinson2017-05-081-11/+6
| | | | | 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
|
* Calculate the output limiter gain using the RMSChris Robinson2017-05-052-30/+78
|
* Rename RollOff to RolloffChris Robinson2017-05-051-4/+4
|
* Increase the HRTF transition to 128 samplesChris Robinson2017-05-051-2/+2
|
* Implement cross-platform embedding of HRTF dataalexey.lysiuk2017-05-053-78/+8
|
* Start an extension to change the source's spatialize propertyChris Robinson2017-05-051-1/+4
|
* Add a property to force source spatialization on or offChris Robinson2017-05-041-3/+5
|
* Handle attenuated sources in CalcPanningAndFiltersChris Robinson2017-05-041-377/+442
|
* Calculate the multi-channel panning in a separate functionChris Robinson2017-05-041-249/+249
|
* Finalize AL_SOFT_source_resamplerChris Robinson2017-05-031-1/+1
|
* Add a mixing function to blend HRIRsChris Robinson2017-05-036-27/+90
| | | | | | 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
|
* Remove a duplicate checkChris Robinson2017-05-021-1/+1
|
* Change some ALuint parameters to ALsizeiChris Robinson2017-05-0210-75/+74
|
* Rename VOICE_IS_HRTF to VOICE_HAS_HRTFChris Robinson2017-05-022-5/+5
|
* Rename 'moving' flag to 'fading'Chris Robinson2017-05-021-2/+2
|
* 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 Robinson2017-04-301-5/+18
|
* 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
