* Alter tha curve of the density-related delay scaleChris Robinson2018-02-081-22/+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.

|
* Remove the individual source queue and buffer locksChris Robinson2018-02-024-134/+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 voiceChris Robinson2018-02-012-10/+20
| | | | For more efficient voice lookups when needed.
* Remove unused _timed methodsChris Robinson2018-02-012-123/+0
| | | | | They're not reliably implemented anyway, as some systems will just flat out fail when trying to use them.

* Use semaphores to signal for more samples with JACK and OpenSLChris Robinson2018-02-012-54/+16
|
* Use a semaphore to signal the event handlerChris Robinson2018-02-014-19/+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 a thread to marshal events from the mixerChris Robinson2018-01-313-4/+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.
