* | Reduce the mix buffer sizes by half | Chris Robinson | 2008-07-08 | 1 | -1/+1 |
| | | | | Nearly 3MB is a bit much. Could reduce it further, but this is good enough for now. | ||||
* | Leave SourceToListener untransformed for use with untransformed velocities | Chris Robinson | 2008-07-03 | 1 | -6/+16 |
| | | | | | Distance is also left untransformed so cone calculations with SoundToListener are correct | ||||
* | Fix source calculations for AL_SOURCE_RELATIVE mode | Chris Robinson | 2008-05-18 | 1 | -18/+22 |
| | | | | | | Make sure the source position and direction are properly put into listener- space before working with them, and don't calculate the listener velocity for relative coordinates | ||||

* | Implement AL_EFFECT_REVERB | Chris Robinson | 2008-01-18 | 1 | -19/+98 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is a quick description of how the reverb effect works: +--->---+*(4) | V new sample +-----+---+---+ | |extra|ltr|ref| <- +*(1) +-----+---+---+ (3,5)*| |*(2) +-->| V out sample 1) Apply master reverb gain to incoming sample and place it at the head of the buffer. The master reverb gainhf was already applied when the source was initially mixed. 2) Copy the delayed reflection sample to an output sample and apply the reflection gain. 3) Apply the late reverb gain to the late reverb sample 4) Copy the end of the buffer, applying a decay gain and the decay hf ratio, and add to the late reverb. 5) Copy the late reverb sample, adding to the output sample. Then the head and sampling points are shifted forward, and done again for each new sample. The extra buffer length is determined by the Reverb Density property. A value of 0 gives a length of 0.1 seconds (long, with fairly distinct echos) , and 1 gives 0.075 seconds (short, indistinct echos). The decay gain is calculated such that after a number of loops to satisfy the Decay Time, a sample will be 1/32768th as powerful (virtually insignificant to the resulting output, and only getting further reduced). It is calculated as: DecayGain = pow(1.0f/32768.0f, 1.0/(DecayTime/ExtraLength)); Things to note: Reverb Diffusion is not currently handled, nor is Decay HF Limit. Decay HF Ratios above 1 probably give incorrect results. Also, this method likely sucks, but it's the best I can come up with before release. :) | ||||

| * | Disable fast float-to-int hack. | Chris Robinson | 2008-01-05 | 1 | -0/+2 |
| | | | | | | | | | | Even with precautions, it's giving problems. Not worth it since I don't quite understand how it works, or know if there's even a benefit. | ||||
* | | Try a different low-pass filter | Chris Robinson | 2008-01-05 | 1 | -4/+6 |
| | | | | | | | | | | Seems to be more correct, although it's not as powerful as the previous (which may be a good thing) | ||||

| * | Allow psuedo 6.1 and 7.1 output | Chris Robinson | 2007-12-31 | 1 | -2/+96 |
| | | | | | | | | | | | | This only does spatial calculations on the 4 corner speakers, but it's necessary groundwork for AL_EXT_MCFORMATS support. Spatial calculations for 6 speakers can be added later. | ||||
| * | Use an enum list for dealing with channels | Chris Robinson | 2007-12-31 | 1 | -67/+79 |
| | | | | | | | | This will make it easier to remap channels, especially the center and lfe channels | ||||

| | | |||||
| * | Allow 5.1 channel output | Chris Robinson | 2007-12-26 | 1 | -2/+29 |
| | | | | | | | | This doesn't use the center or LFE channel in spatial calculations, however | ||||
* | | Zero out wet send params when calculating source params | Chris Robinson | 2007-12-31 | 1 | -38/+62 |
