| * | Implement a skeleton Ring Modulator effect | Chris Robinson | 2010-04-08 | 1 | -0/+1 | |

| * | Move extension function declarations to alext.h/efx.h | Chris Robinson | 2010-03-23 | 1 | -13/+0 | |

| * | Mark extension functions with AL_API/ALC_API | Chris Robinson | 2010-03-23 | 1 | -13/+13 | |

| * | Add EFX types and enums to alext.h | Chris Robinson | 2010-03-09 | 1 | -6/+0 | |
| | | | | | | The types and enums are in efx.h, which is included by alext.h. It's done this way because EFX has a lot if definitions which would polute alext.h | |||||
| * | Handle NULL effect objects as AL_EFFECT_NULL effects | Chris Robinson | 2009-11-05 | 1 | -0/+1 | |
| | | ||||||
| * | Add a method to update device-dependant effect parameters. | Chris Robinson | 2009-10-20 | 1 | -0/+2 | |
| | | | | | The effect state's update method will be called afterwards | |||||
| * | Be context-agnostic in the effect Create functions | Chris Robinson | 2009-10-19 | 1 | -4/+4 | |
| | | | | | | | | This allows the effect Update functions to handle the playback frequency being changed. By default the effects assume a maximum frequency of 192khz, however, it can go higher at the cost of the sample buffers being cleared and the risk of an abort() if reallocation fails | |||||
| * | Apply slot gain on slot output, not input | Chris Robinson | 2009-05-29 | 1 | -5/+5 | |

| * | Move the WetBuffer into the effect slot object | Chris Robinson | 2009-04-11 | 1 | -0/+2 | |
| | | | | | This should make it easier to support multiple slots | |||||
| * | Implement a new reverb effect | Chris Robinson | 2008-11-16 | 1 | -9/+2 | |
| | | | | | Code created and graciously provided by Christopher Fitzgerald | |||||

| * | Implement yet another low-pass filter | Chris Robinson | 2008-07-25 | 1 | -2/+4 | |
| | | | | | This one using the Butterworth IIR filter design | |||||
| * | Implement AL_EFFECT_REVERB | Chris Robinson | 2008-01-18 | 1 | -0/+9 | |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. :) | |||||
