* Don't store the effect slot in SendParamsChris Robinson2013-10-061-5/+24
| | | | This makes it much more like DirectParams.
* Rename Filter param member to LpFilterChris Robinson2013-10-061-4/+4
|
* Use a separate value for the maximum buffer channelsChris Robinson2013-07-231-2/+2
| | | | | | | Unlike the device, input buffers are accessed based on channel numbers instead of enums. This means the maximum number of channels they hold depends on the number of channels any one format can have, rather than the total number of recognized channels. Currently, this is 8 for 7.1.
* Improve the source's low-pass filter responseChris Robinson2013-07-201-4/+4
|
* Limit the source step to 10Chris Robinson2013-07-021-14/+4
| | | | | | | | | This means the combination of the buffer frequency, source pitch, and doppler shift can't exceed 10x the device playback frequency. This is needed to keep the mixer from starving with a really high increment, causing small DstBufferSize values that require a lot of iterations.
* Fix up the naming convention of effect methodsChris Robinson2013-05-291-4/+4
|
* Use C99's inline instead of __inlineChris Robinson2013-05-281-12/+12
|
* Use the high-shelf filter in place of low-passChris Robinson2013-05-281-4/+4
| | | | | They effectively both work to lower (or raise) high frequencies. However, the high-shelf performs better when gain=1.
* Simplify and fix some filter gain calculationsChris Robinson2013-05-271-6/+12
|
* Use ALfilterState for the source direct and send filtersChris Robinson2013-05-271-22/+17
|
* Use generic VCALL[_NOARGS] macros instead of type-specific wrappersChris Robinson2013-05-271-6/+6
|
* Use an ALeffectProps union to store the effect propertiesChris Robinson2013-05-251-6/+6
|
* Use restrict instead of RESTRICTChris Robinson2013-05-221-5/+5
|
* Use a properly-defined history for the FILTER structChris Robinson2013-05-211-5/+9
|
* Fix overflow issues when converting float to intChris Robinson2013-04-221-7/+10
| | | | | | | | 32-bit floats can only reach between -16777215...+16777215 (25 bits) before it starts losing whole-number accuracy. Some compiler optimizations may break trying to multiply a float by 2147483647.0 when the result is given right to a float parameter, causing it instead to multiply by the nearest representable float value, 2147483648.0.
* Add a missing cast to silence MSVCChris Robinson2013-03-221-1/+1
|
* Use less math to clamp floats to -1...+1Chris Robinson2013-03-171-3/+3
| | | | | The previous code could have issues as precision lowers. This should hopefully work better while only using one if check instead of two.
* Use +/-90 degrees for stereo sources with non-HRTF stereo output.Chris Robinson2012-12-041-1/+9
|
* Lock the device before calling aluHandleDisconnectChris Robinson2012-12-021-2/+0
| | | | | | PulseAudio causes an assert if being relocked inside a callback on the worker thread, where aluHandleDisconnect is called. We can assume it's already locked there, so just make sure the device is locked before being calling it.
* Use an array to specify the offset for each channel of the device bufferChris Robinson2012-11-041-5/+8
| | | | This effectively inverts the DevChannels array
* Make a decimal value a float typeChris Robinson2012-10-311-1/+1
|
* Add a couple comments to the codeChris Robinson2012-10-261-0/+2
|
* Avoid branching when clamping and converting float samples to integerChris Robinson2012-10-261-2/+2
|
* Move some math functions to where they're usedChris Robinson2012-10-251-0/+25
|
* Put the HRTF DirectParams into an anonymous structChris Robinson2012-10-151-26/+26

* Store the output buffers in the DirectParams structChris Robinson2012-10-141-1/+9
|
