* | Remove unused reverb modulation code | Chris Robinson | 2018-02-10 | 1 | -107/+2 |
| | | | | | | Still unsure how to handle reverb modulation without some kind of reference output, so remove the related functions to not waste CPU time. It'll remain in the Git history should it ever need to be resurrected. | ||||
* | Use a function pointer for applying the dry mix post-process | Chris Robinson | 2018-02-10 | 4 | -70/+106 |
| | |||||
* | Use an alternate virtual layout for Ambisonic HRTF decoding | Chris Robinson | 2018-02-10 | 3 | -48/+76 |
| | | | | | This uses 16 channels, an 8-channel octagon + 8-channel cube, which should improve horizontal resolution without affecting vertical too much. | ||||
* | Clarify some macro names using ambisonic mixed-mode notation | Chris Robinson | 2018-02-09 | 3 | -32/+32 |
| | |||||
* | Attempt to improve the reverb panning vectors | Chris Robinson | 2018-02-08 | 1 | -20/+42 |
| | | | | | This should now retain the original orientation of the soundfield and merely focus on the panning vector direction, as intended. | ||||
* | Alter tha curve of the density-related delay scale | Chris Robinson | 2018-02-08 | 1 | -22/+33 |
| | | | | | | | | | | | | | | | | | | | The delay scale is roughly linear with respect to room size, however the density is not linear with room size. The density is calculated by taking the room size cubed, then normalized by some factor. Unnormalizing the density and taking the cube root restores the original room size to use as a delay scale. The patch also alters the delay and all-pass line lengths to be based on a 1 meter room size, so the the room size recovered from the density acts as a direct multiple for the desired target length. Note that the room scale range is unchanged (5m to 50m), so the minimum and maximum delays are the same. It should also be noted that 50m may not be the correct room size for a density value of 1. A density value of 1 corresponds to an environment size of roughly 2.52m when converted from EAX (DENSITY_SCALE should be 16 rather than 125000), but sizes that low result in undesirable resonance in the feedback, indicating other changes are necessary for that to work. | ||||

* | Revert "Don't fade the all-pass delay changes" | Chris Robinson | 2018-02-04 | 1 | -28/+48 |
| | | | | This reverts commit 799dfb732b4f49198d72649e86955ea82f45f229. | ||||

* | Remove the unused thunk code | Chris Robinson | 2018-02-02 | 9 | -138/+0 |
| | |||||
* | Remove the individual source queue and buffer locks | Chris Robinson | 2018-02-02 | 4 | -134/+24 |
| | | | | | | | They're inherently protected by the mutex for their respective lists. Should those mutexes be replaced by rwlocks the individual locks should also be reinstated, but they're unlikely to be unless a lot of contention starts happening in the read-only case. | ||||
* | Store an index to a given source's voice | Chris Robinson | 2018-02-01 | 2 | -10/+20 |
| | | | | For more efficient voice lookups when needed. | ||||
* | Remove unused _timed methods | Chris Robinson | 2018-02-01 | 2 | -123/+0 |
| | | | | | They're not reliably implemented anyway, as some systems will just flat out fail when trying to use them. | ||||
* | Don't generate Buffer Completed events for static sources | Chris Robinson | 2018-02-01 | 1 | -9/+34 |
| | |||||
* | Avoid an unnecessary temp variable | Chris Robinson | 2018-02-01 | 1 | -8/+6 |

* | Use an atomic instead of volatile to tell a thread to quit | Chris Robinson | 2018-02-01 | 1 | -6/+5 |

* | Use semaphores to signal for more samples with JACK and OpenSL | Chris Robinson | 2018-02-01 | 2 | -54/+16 |
| | |||||
* | Use a semaphore to signal the event handler | Chris Robinson | 2018-02-01 | 4 | -19/+9 |
| | | | | | | | | | | | Semaphores allow for semi-persistent signals, compared to a condition variable which requires a mutex for proper detection. A semaphore can be 'post'ed after writing some data on one thread, and another thread will be able to recognize it quickly even if the post occured in between checking for data and waiting. This more correctly fixes a race condition with events since the mixer shouldn't be using mutexes, and arbitrary wake-ups just to make sure an event wasn't missed was quite inefficient. | ||||
* | Add semaphore functions to the thread API wrapper | Chris Robinson | 2018-02-01 | 2 | -0/+96 |

| | |||||
* | Add a thread to marshal events from the mixer | Chris Robinson | 2018-01-31 | 3 | -4/+105 |
| | | | | | | To avoid having unknown user code running in the mixer thread that could significantly delay the mixed output, a lockless ringbuffer is used for the mixer to provide events that a secondary thread will pop off and process. | ||||
* | Rename EventLock to make it more clear it's protecting the callback | Chris Robinson | 2018-01-30 | 5 | -11/+9 |

* | Move some inline functions into a header instead of copying them | Chris Robinson | 2018-01-27 | 5 | -35/+36 |
| | | | | | Unfortunately does not include the Lookup* functions, which need the full type declaration to offset the pointer. | ||||
