* Add a GCC-specific STATIC_UPCAST macro that checks the object typeChris Robinson2014-04-191-1/+8
| | | | | The check is compile time, and is functionally identical to the old/alternate version.
* Use C11 alignas when availableChris Robinson2014-04-191-11/+6
|
* Use C11's static_assert when availableChris Robinson2014-04-071-0/+12
|
* Use an al_string for the device nameChris Robinson2014-03-281-1/+2
|
* Use C99 VLA instead of alloca when availableChris Robinson2014-03-251-0/+6
|
* Remove the last bits of the predictive sample processingChris Robinson2014-03-231-3/+3
|
* Remove the now-unneeded click removal buffers for the deviceChris Robinson2014-03-231-3/+0
| | | | | | They are still there for auxiliary sends. However, they should go away soon enough too, and then we won't have to mess around with calculating extra "predictive" samples in the mixer.
* Use a void* for the effect state Delete method paramChris Robinson2014-03-211-0/+3
|
* Add a generic vector interface and use it for the active effect slotsChris Robinson2014-03-211-3/+6
|
* Use flexible array members to pad the device and context structsChris Robinson2014-03-201-0/+6
| | | | | This helps avoid the convoluted math otherwise required to ensure the default slot and listener, respectively, are aligned.
* Keep track of the mix countChris Robinson2014-03-191-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | The purpose of this is to provide a safe way to be able to "swap" resources used by the mixer from other threads without the need to block the mixer, as well as a way to track when mixes have occurred. The idea is two-fold: It provides a way to safely swap resources. If the mixer were to (atomically) get a reference to an object to access it from, another thread would be able allocate and prepare a new object then swap the reference to it with the stored one. The other thread would then be able to wait until (count&1) is clear, indicating the mixer is not running, before safely freeing the old object for the mixer to use the new one. It also provides a way to tell if the mixer has run. With this, a thread would be able to read multiple values, which could be altered by the mixer, without requiring a mixer lock. Comparing the before and after counts for inequality would signify if the mixer has (started to) run, indicating the values may be out of sync and should try getting them again. Of course, it will still need something like a RWLock to ensure another (non-mixer) thread doesn't try to write to the values at the same time. Note that because of the possibility of overflow, the counter is not reliable as an absolute count.

* Avoid GCC's macro arg concat extension with IDE parsingChris Robinson2014-03-171-1/+1
|
* Add an extension to support MSADPCM buffer formatsChris Robinson2014-03-041-0/+6
|
* Add an extension to alter the block alignment for buffer unpack/pack opsChris Robinson2014-03-041-0/+6
| | | | | | | | | | | | | | | | This is for unpacking (reading, e.g. alBufferData) and packing (writing, e.g. alGetBufferSamplesSOFT) operations. The alignments are specified in sample frames, with 0 meaning the default (65 for IMA4, 1 otherwise). IMA4 alignment must be a multiple of 8, plus 1 (e.g. alignment = n*8 + 1), otherwise an error will occur during (un)packing. Chenging the block alignment does not affect already-loaded sample data, only future unpack/pack operations... so for example, this is perfectly valid: // Load mono IMA4 data with a block alignment of 1024 bytes, or 2041 sample // frames. alBufferi(buffer, AL_UNPACK_BLOCK_ALIGNMENT_SOFT, 2041); alBufferData(buffer, AL_FORMAT_MONO_IMA4, data, data_len, srate); alBufferi(buffer, AL_UNPACK_BLOCK_ALIGNMENT_SOFT, 0);
* Move PATH_MAX fallback definitions to alMain.hChris Robinson2014-02-271-0/+9

* Move OpenDataFile to helpers.c so other sources can use itChris Robinson2014-02-271-0/+1
|
* Move HRTF macros and function declarations to a separate headerChris Robinson2014-02-231-14/+0
|
* Add a return value to FindHrtfFormatChris Robinson2014-02-231-1/+1
|
* Add an alcGetInteger64vSOFT method and a way to get the device clockChris Robinson2014-02-011-0/+11
|
* Keep track of a device clock time, based on the number of samples processedChris Robinson2014-02-011-0/+7
|
* Rename aftertouch to keypressureChris Robinson2014-01-171-6/+6
|
* Handle fontsound sample types using explicit enum valuesChris Robinson2014-01-151-0/+2
| | | | | | Uses AL_MONO_SOFT, AL_RIGHT_SOFT, and AL_LEFT_SOFT. "Linked" samples types aren't explicitly supported due to being under-defined in the SF2 spec, nor are ROM samples currently.
* Add a flag to specify the device being pausedChris Robinson2014-01-151-0/+3
| | | | | Used to prevent UpdateDeviceParams from restarting the device, if a new context is created while paused.

| | | | | | | | | | | | | | | | | | | | | Some hefty caveats: This function is not thread-safe. In particular, the current context affecting the thread must not be changed, and the provided soundfont must not be altered while the function is executing. Ideally, this will be fixed. Error handling is poor. Some RIFF structure errors may not be caught (e.g. sub- chunks with sizes greater than the parent chunk allows for), and generated AL errors are ignored, possibly leading to resource leaks in certain situations. These should be fixed in time. There is minimal error checking on the provided soundfont ID. It does not ensure a valid ID has been provided, nor does it ensure the provided soundfont can be modified. These short-comings should be fixed eventually. Proper cleanup is the responsibility of the caller. The caller must get the preset objects from the soundfont before deleting it, and the fontsound objects from each preset before deleting them, to make sure all resources are properly deleted.
* Add a method to set and get soundfontsChris Robinson2013-12-271-4/+12
| | | | | The main purpose of this is to select soundfonts for playback, eventually, instead of the existing method that takes a filename.
* Allow specifying some fontsound sample propertiesChris Robinson2013-12-261-0/+9
|
* Allow specifying key and velocity ranges on fontsoundsChris Robinson2013-12-261-0/+10

* Remove the zone, sample, and instrument object typesChris Robinson2013-12-251-10/+0
|
* Add a new fontsound object typeChris Robinson2013-12-251-0/+11
| | | | This is basically a combined preset and intrument zone with sample header.
