* Make the filter functions global inline, and use it for echoChris Robinson2009-05-161-0/+33
|
* Set some common macros in alu.hChris Robinson2009-05-162-5/+46
|
* Make the filter history buffer size flexibleChris Robinson2009-04-162-1/+3
| | | | | | | This lets the filter history buffer be as big as needed for a given use, so that it can have a size large enough for the more demanding cases, but not be wasteful for lesser-demanding cases, while not incuring the overhead of an added pointer indirection
* Add a PulseAudio backendChris Robinson2009-04-161-0/+1
|
* Increase the default maximum number of sends to 2Chris Robinson2009-04-141-1/+1
|
* Make the number of source sends variableChris Robinson2009-04-131-0/+2
| | | | The highest value is clamped to MAX_SENDS
* Add the Echo effectChris Robinson2009-04-123-0/+60
|
* Pay attention to the MAX_SENDS valueChris Robinson2009-04-111-2/+1
|
* Make auxiliary effect slot count configurableChris Robinson2009-04-111-0/+2
|
* Move the WetBuffer into the effect slot objectChris Robinson2009-04-112-0/+4
| | | | This should make it easier to support multiple slots
* Remove the SDL backendChris Robinson2009-03-101-1/+0
|
* Add a PortAudio backendChris Robinson2009-03-101-0/+1
|
* Use a matrix for up- and down-mixing channelsChris Robinson2009-01-251-0/+2
|
* 6.1 uses front- and back-center, not left- and right-back channelsChris Robinson2009-01-241-1/+2
|
* Reimplement panning using lookup tables, based on a patch by Christian BorssChris Robinson2009-01-242-0/+7
| | | | | | This allows speaker positions to be specified by discrete angles around the listener, providing more flexibility and configurability in placement. Additional patches to take advantage of this are forthcoming.
* Apply the dry filter to multi-channel sourcesChris Robinson2008-12-101-1/+2
| | | | Unlike mono sources, they use 2 chained one-pole filters instead of 4
* Add an SDL backendChris Robinson2008-12-071-0/+1
|
* Implement AL_EXTX_source_distance_modelChris Robinson2008-11-251-0/+1
| | | | | As with other EXTX extensions, this is subject to change and removal as the spec gets worked on
* Remove unneeded macroChris Robinson2008-11-161-1/+0
|
* Implement a new reverb effectChris Robinson2008-11-162-9/+28
| | | | Code created and graciously provided by Christopher Fitzgerald
* Add an option to disable specific EFX effect typesChris Robinson2008-11-141-0/+7
|
* Don't ramp gains when starting a sound from the beginningChris Robinson2008-11-131-0/+1
|
* Add initial AL_EXTX_buffer_sub_data supportChris Robinson2008-11-111-0/+2
| | | | | | | | Note that this is an in-development extension, as noted by the EXTX moniker instead of EXT. It's behavior is subject to change, and the extension string will be removed (replaced with the official string once it's finalized). Developers are discouraged from using this in production code, though feel free to play around with it.
* Remove another unused source memberChris Robinson2008-10-101-2/+0
|
* Remove unneeded source member variableChris Robinson2008-10-091-1/+0
|
* Commit missing changesChris Robinson2008-10-091-1/+1
|
* Use a new low-pass filter, based on the I3DL2 specChris Robinson2008-10-022-6/+3
| | | | Many thanks to Christopher Fitzgerald, for helping with it
* Air absorption factor is applied to the dB value, not linear gainChris Robinson2008-09-221-0/+1
|
* Use a 12dB/oct rolloff instead of 24 for the lowpass filterChris Robinson2008-09-131-4/+2
|
* Add a Solaris playback backendChris Robinson2008-09-071-0/+1
|
* Don't export extension function symbols from the libChris Robinson2008-09-063-39/+39
|
* Remove unneeded source struct memberChris Robinson2008-08-151-1/+1
|
* Ramp channel gains to remove pops and clicks from abrupt changesChris Robinson2008-08-142-0/+20
| | | | Thanks to Christopher Fitzgerald for helping me work on it
* Include fenv.h if it exists for fesetroundChris Robinson2008-08-081-0/+4
|
* Use arrays instead of pointer-to-arrays for the low-pass filterChris Robinson2008-07-261-4/+4
|
* Make the filter processing function inlineChris Robinson2008-07-261-1/+2
|
* Implement yet another low-pass filterChris Robinson2008-07-253-2/+14
| | | | This one using the Butterworth IIR filter design
* Specify padding per buffer, and make sure it's large enough for the filter stepChris Robinson2008-07-242-0/+4
|
* Implement an alternative low-pass filterChris Robinson2008-07-231-3/+0
| | | | | | | | | This method samples from the buffer so that it gets a time-correct 5khz stream, which is subtracted from the original sample and has the high-frequency gain applied, then added back. A better method may be to average all the samples from the current one to the one freq/5000 away, instead of bilinear filtering the two nearest freq/5000 apart. Processing cost will need to determine its viability
* Store extension list with a pointer, not a per-context arrayChris Robinson2008-07-221-1/+1
|
* Move (de)initialization into ALc.c and remove unneeded fileChris Robinson2008-07-171-2/+0
|
* Implement doppler factor source propertyChris Robinson2008-07-151-0/+2
|
* Use pthread_mutexattr_setkind_np as a fallback to set a recursive mutex typeChris Robinson2008-05-151-0/+7
| | | | Some systems (FreeBSD) don't like setting it through pthread_mutexattr_settype
* constify the pointer that holds the filenameChris Robinson2008-03-221-8/+8
|
* Define _WIN32_WINNT to 0x0500 when including windows.hChris Robinson2008-03-011-0/+3
| | | | VC7 appears to require that value, or higher, set and fails otherwise
* Remove FrameSize struct memberChris Robinson2008-02-141-1/+0
|
* Rename UpdateFreq device field to UpdateSizeChris Robinson2008-02-121-1/+1
|
* Include alext.h instead of redefining some enumsChris Robinson2008-02-081-27/+4
|
* Remove unneeded device struct memberChris Robinson2008-02-081-1/+0
|
* Add an option for duplicating stereo sources on the back speakersChris Robinson2008-02-061-0/+2
