* | Reimplement bilinear interpolation between HRIRs | Chris Robinson | 2017-05-01 | 1 | -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 state | Chris Robinson | 2017-04-30 | 1 | -2/+12 |
| | |||||
* | Start an extension to toggle the output limiter | Chris Robinson | 2017-04-30 | 2 | -5/+23 |
| | |||||
* | Don't do more reverb samples than there are to fade. | Chris Robinson | 2017-04-28 | 1 | -2/+6 |
| | | | | This avoids having to clamp the fade value when incrementing it. | ||||
* | Fade HRTF coefficients over 64 samples at most | Chris Robinson | 2017-04-28 | 1 | -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 functions | Chris Robinson | 2017-04-27 | 1 | -121/+50 |
| | |||||
* | Properly update the delay line offsets when fading is done | Chris Robinson | 2017-04-27 | 1 | -28/+44 |
| | |||||
* | Write directly to the output for HRTF | Chris Robinson | 2017-04-27 | 1 | -51/+26 |
| | |||||
* | Document the output-limiter config option | Chris Robinson | 2017-04-26 | 3 | -4/+47 |
| | | | | Expose it in alsoft-config as well. | ||||
* | Implement a limiter on the device output | Chris Robinson | 2017-04-26 | 3 | -4/+72 |
| | | | | | | This reduces the output volume when the mixed samples extend outside of -1,+1, to prevent excessive clipping. It can reduce the volume by -80dB in 50ms, and increase it by +80dB in 1s (it will not go below -80dB or above 0dB). | ||||
* | Compile with -fno-math-errno when available | Chris Robinson | 2017-04-26 | 1 | -0/+5 |
| | | | | Helps GCC to inline some fp functions, e.g. lrintf | ||||
* | Reverb code update | Chris Robinson | 2017-04-26 | 1 | -824/+1213 |
| | | | | | | | | | | | | | | This update modifies the reverb in numerous ways. The 3-series, 4-parallel all-pass is replaced with a Gerzon vector all-pass. The vector all-pass is also applied to the early reflections, to help with the initial diffusion in the late reverb. The late reverb filter and feedback attenuation has been replaced with a dual first-order equalization filter, which controls the low and high frequencies with individual low-pass/high-shelf and high-pass/low-shelf filters with gain control. Additionally, delay lines now have the ability to blend the output between two offsets, to help smooth out the transition for when the delay changes (without such, it could result in undesirable clicks and pops). | ||||
* | Skip mixing the fade out step when starting silent | Chris Robinson | 2017-04-25 | 1 | -12/+19 |
| | | | | | Unfortunately it can't skip mixing the fade in when going to silence because the history needs to be up to date. | ||||
* | Remove const from _Atomic vars to make Clang happy | Chris Robinson | 2017-04-21 | 5 | -19/+42 |
| | | | | | | | | Clang does not allow using C11's atomic_load on const _Atomic variables. Previously it just disabled use of C11 atomics if atomic_load didn't work on a const _Atomic variable, but I think I'd prefer to have Clang use C11 atomics for the added features (more explicit memory ordering) even if it means a few instances of breaking const. | ||||

| | |||||
* | Add the ability to change the source resampler | Chris Robinson | 2017-04-21 | 2 | -1/+24 |

* | Check for the upsampler to determine if HRTF uses HOA | Chris Robinson | 2017-04-18 | 1 | -15/+12 |

* | Use a different way to get the size of structs with flexible array members | Chris Robinson | 2017-04-18 | 8 | -17/+17 |
| | |||||
* | Store the source queue head in the voice to signify looping | Chris Robinson | 2017-04-18 | 4 | -163/+153 |
| | | | | | This removes the need to access a couple more source fields in the mixer, and also makes the looping and queue fields non-atomic. | ||||

* | Allow increasing the maximum source limit | Chris Robinson | 2017-04-14 | 4 | -19/+69 |
| | | | | | | | | If the requested number of mono and stereo sources exceeds 256, the source limit will be expanded. Any config file setting overrides this. If the device is reset to have fewer sources than are currently allocated, excess sources will remain and be usable as normal, but no more can be generated until enough are delated to go back below the limit. | ||||
