|
* Generate the bsinc tables using constexpr methodsChris Robinson2020-04-021-2/+2
| | | | | | | | All the methods used should be compliant with C++14 constexpr rules. However, the number of scales and phases cause GenerateBSincCoeffs to reach the allowed step limit, preventing full compile-time generation. It's not a terribly big deal, it'll generate them very quickly when loading, but it does prevent using shared read-only memory pages.
* Move the FrontStablizer definition to its own headerChris Robinson2020-03-301-0/+1

|
* Dynamically allocate voice channel dataChris Robinson2020-03-251-16/+15
| | | | | | | Rather than allocating for a full 8 channels for each voice, when the vast majority will only need 1 or 2. The voice channel data is relatively big since it needs to hold HRTF coefficients and history, and this will allow increasing the maximum number of buffer channels without an obscene memory increase.
* Avoid assigning in a conditional expressionChris Robinson2020-03-221-1/+3

* Move the FPUCtl methods to its own sourceChris Robinson2020-03-201-1/+1
|
* Fix voices being forced to update without valid propertiesChris Robinson2020-03-041-14/+7
| | | | | | | | | | | | | | | | When starting a voice, the source ID was set before its first update struct was provided, creating a small window where a listener or effect slot update could force a voice to update without it having any valid properties to update with. Supplying the update struct first would create a different race, where the mixer could see a voice without a source but with an update struct, causing the update struct to be 'freed' without being applied. The fix here is to provide the update struct before setting the source ID, and change the mixer to ignore update structs for voices without a source ID. This can pseudo-orphan the updates that get set on a voice just as it stops, leaving the struct unusable until the voice is used again, or the voice gets deleted which will clear it. But it allows the update struct to stay in place and get applied once the voice gets a source ID.
* Use a new voice state to indicate a pending source offset changeChris Robinson2020-03-041-5/+6

* Use an intrusive_ptr for the device's HrtfStoreChris Robinson2020-03-011-2/+2
|
* Use a VoiceChange object to change the offset of a playing sourceChris Robinson2020-02-261-0/+26
|
* Rename the voice's PendingStop to PendingChangeChris Robinson2020-02-261-2/+2
|
* Simplify replaying a sourceChris Robinson2020-02-231-7/+28
|
* Avoid a single function call in a loopChris Robinson2020-02-211-68/+66
|
* Use an array of ALvoice pointers for the active voicesChris Robinson2020-02-211-13/+14
| | | | | | This allows growing the array atomically with the mixer since the ALvoice objects themselves don't move, and a new larger array of them can be swapped in without blocking the mixer.

|
* Start a new extension for a new direct_channels stateChris Robinson2019-12-281-7/+9
| | | | | So existing behavior remains consistent for anything that needs it, and new behavior is opt-in.

|
* Handle padding between device sample framesChris Robinson2019-12-211-17/+17
| | | | | | | | The padding must be constant and sample type aligned (e.g. some fixed multiple of two bytes between the start of two consecutive frames for 16-bit output). The intent is to always have the ability for stereo output with WASAPI even if the device has some other unsupported configuration, as long as front-left and front-right exist.
