43740a4b2f Adds support for stereo output. 2020-02-16 14:14:10 -05:00

f99d672237 The macOS port now selects stereo output if appropriate. 2020-02-16 14:05:50 -05:00

dac217c98c Defers starting the macOS audio queue, and attempts to restart it upon packet loss.
Hopefully forever to vanish permanent audio loss?

f7decd80b6 As an initial step, ensured latency doesn't pile up endlessly. 2018-05-15 21:12:43 -04:00

5d6b5d9f10 Eliminates all emdashes in cross-platform code. 2018-05-13 15:34:31 -04:00

d751b7e2cb Marginally reformats for current style. 2018-02-11 20:32:59 -05:00

bdd432fe1d Added an ugly workaround for the empirical sound shutdown issues. 2017-03-26 20:28:04 -04:00

b193248056 Ensured that queue is not touched at all outside of the critical section. 2017-03-11 18:17:09 -05:00

38ce4dc56c Fixed potential deadlock, if a delegate decided to dealloc the queue as a result of its prompting. 2017-03-11 17:44:02 -05:00
Thomas Harte
2f0c923c29 Switched away from @synchronized as it appears possibly to be the lock used during -dealloc, creating deadlock with the CSAudioQueueDeallocLock. 2017-02-22 21:42:10 -05:00
Thomas Harte
4c947ad553 Attempted to resolve risk of an audio callback being in progress when -dealloc is received. 2017-02-22 21:12:59 -05:00
Thomas Harte
1d03793f22 Fixed potential race condition: ensure the queue is disposed of synchronously because otherwise there'll be a potential dangling reference to self. 2017-02-22 07:35:09 -05:00
Thomas Harte
91831b6a95 Introduced a reuse list for audio buffers, based on the observation that the audio queue seems to start quick rejecting them. 2016-10-23 21:17:00 -04:00

7c33c34b0c Have withdrawn attempt to be clever with client notification here, as it was having no effect in the current environment, making it hard to build up any confidence. 2016-10-23 20:33:59 -04:00

5a808d789a Added an upper threshold that must be crossed before a lower threshold warning is communicated. 2016-10-18 22:21:34 -04:00

f6b6ec7009 Cemented new meaningof the audio queue delegate callout. 2016-10-17 08:18:32 -04:00

c105f2acd9 Sought to reduce chattiness. 2016-10-17 08:04:36 -04:00

f4b39c4435 Added documentation and experimentally reduced packet size. We'll see. 2016-10-10 07:42:24 -04:00

de397799ed Pulled away my crazy rationalisation of an audio queue into a circular buffer and decided just to trust the OS. This should reduce latency. 2016-10-10 07:30:00 -04:00
Thomas Harte
6079d30e58 Eliminated waiting here — either the buffer can be enqueued now or it is dropped. 2016-08-14 16:20:24 -04:00

097a9caa95 Delegates are all nullable, naturally. 2016-06-23 09:37:49 -04:00

090e92ad26 Making this large has very limited side effects. So why not? 2016-06-16 21:41:17 -04:00

3b71d1a309 Switched to a variable-length buffer based on attempting to hit approximately a certain quality of service. 2016-06-16 21:35:22 -04:00
Thomas Harte
2ee78d42b9 Made an attempt also to trigger updates upon audio packets being returned, and significantly to reduce the size and quantity of those. This should get down to 11ms latency if the output wave is 44100; I might need to scale up the buffer size as the sampling rate increases or this is going to get crazy at 192Khz. 2016-06-16 20:51:35 -04:00

ce59ad1911 Minor on-disk shuffle, to try to clarify ownership of responsibility. 2016-06-15 08:11:30 -04:00
