* Only use fast float-to-int workarounds for x87Chris Robinson2018-04-211-0/+18
| | | | | | At least SSE and ARM have opcodes that handle float-to-int conversions well enough. Also, Clang doesn't inline lrintf, incurring function call overhead for what should be a single opcode.
* Improve ASSUME for ClangChris Robinson2018-04-211-0/+9
| | | | | | | | For some reason, the { if(!x)__builtin_unreachable(); } construct does not provide the same optimization opportunity for Clang (even though the condition being false would trigger undefined behavior by reaching unreachable code, it still performs checks and such for the condition potentially being false). Using __builtin_assume seems to work better.
* Add an ASSUME macro that requires a true conditionChris Robinson2018-04-171-0/+17

* Rename BiquadState to BiquadFilterChris Robinson2018-04-041-4/+4

|
* EFX:Pitch Shifter implementationRaulshc2018-03-184-1/+16
| | | Add pitch shifter effect using standard phase vocoder, based on work of Stephan Bernsee. Only mono signal processing by now.
* Apply a distance decay on the source send for the reverb's DecayLFRatioChris Robinson2018-03-112-0/+2
|
* Add extern "C" to some headersChris Robinson2018-03-091-17/+17
|
* Use function-like macros to call filter and effect vtable methodsChris Robinson2018-03-084-33/+49
|
* Fix struct forward declaration typoChris Robinson2018-03-081-1/+1
|
* Fix adding to and removing from the active effect slotsChris Robinson2018-03-081-21/+35
| | | | | It wasn't properly removing all duplicates on insertion, and didn't remove the first effect slot when removing them.
* Properly limit the max number of effect slots to 2^31 - 1Chris Robinson2018-03-081-9/+1
|
* Don't check for space in the ringbuffer before trying to writeChris Robinson2018-03-032-5/+3
| | | | The write method already checks and returns how much it managed to fit in.
* Avoid some code duplicationChris Robinson2018-03-031-12/+8
|
* Add some missing locks to protect reading stateChris Robinson2018-03-032-0/+16

* Use a plain mutex for the property lockChris Robinson2018-03-035-90/+65
|
* Use atomic variables instead of volatileChris Robinson2018-03-021-2/+2
|
* Add an option to limit the write size of the ringbufferChris Robinson2018-03-011-1/+1
|
* Fix a comment regarding the effect slot channel scalingChris Robinson2018-02-281-3/+3
|
* Avoid AL prefix on internal effect state factory typesChris Robinson2018-02-282-39/+40
| | | | Also avoid using the generic V/V0 macros for them
* Avoid using static inline in headersChris Robinson2018-02-251-4/+4
|
* Count all buffers in a list item for processed and queuedChris Robinson2018-02-251-34/+51

* Don't make the source state atomicChris Robinson2018-02-242-24/+17
|
* Handle source state change eventsChris Robinson2018-02-241-11/+56

* Combine multiple functions called sequentiallyChris Robinson2018-02-112-7/+3
|
* Clear stale 'post's on the event semphaphoreChris Robinson2018-02-111-0/+5
|
* Use a function pointer for applying the dry mix post-processChris Robinson2018-02-102-2/+7
|
* Remove unsupported source queriesChris Robinson2018-02-041-124/+0
|
* Make the Connected state atomicChris Robinson2018-02-042-2/+2
| | | | Also don't send the Disconnected event more than once.
* Provide more descriptive messages to disconnection eventsChris Robinson2018-02-031-1/+1
|
* Add a couple missing lock callsChris Robinson2018-02-031-0/+4
|
* Add a disconnected event typeChris Robinson2018-02-033-1/+4
|
* Remove the unused thunk codeChris Robinson2018-02-027-133/+0
|
* 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.
* Use a semaphore to signal the event handlerChris Robinson2018-02-012-16/+5
| | | | | | | | | | | 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.
* Send buffer completed events when enabledChris Robinson2018-02-011-1/+1
|
* Fix check for matching event typeChris Robinson2018-02-011-1/+1
|
* Add a thread to marshal events from the mixerChris Robinson2018-01-312-3/+86
| | | | | | 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 callbackChris Robinson2018-01-304-9/+7
|
* Fix the effect slot limit checkChris Robinson2018-01-281-1/+1
|
* Make EnabledEvts atomicChris Robinson2018-01-284-7/+26

* Use a fixed array for the effect state factory listChris Robinson2018-01-282-31/+24

* Don't bother with a return value that's never usedChris Robinson2018-01-272-7/+6
