* Avoid taking the square-root of the ambient gainChris Robinson2014-10-111-3/+3
| | | | | | Although it is more correct for preserving the apparent volume, the ambisonics- based panning does not work on the same power scale, making it louder by comparison.
* Combine some fields into a structChris Robinson2014-09-101-1/+1

* Use logarithmic adjustment for the gain in the autowah effectChris Robinson2014-05-171-7/+7

* Use a void* for the effect state Delete method paramChris Robinson2014-03-211-5/+2

* Change the autowah to have a cutoff range of 20Hz to 20KHzChris Robinson2014-02-071-1/+1
| | | | | | This is the same as allowed in the SF2 spec for its filter cutoff generator, which can be used for a wah effect in MIDI. It makes sense to use a similar range here.
* Fix some typesChris Robinson2014-02-071-2/+2
|
* Use a different autowah filter rangeChris Robinson2013-12-201-1/+1
| | | | Still just guesses, but this seems to avoid math problems with low peak gains.
* Redo the autowah effectChris Robinson2013-11-071-71/+71
| | | | | | | | It's now a low-pass filter with a cutoff that varies according to the input signal amplitude. There remains issues with apparent feedback in the resonant frequency with high resonance values. The actual cutoff range for the filter is also a guess.
* Use a helper macro for pi*2Chris Robinson2013-10-081-1/+1

* Use helpers to set channel gain arraysChris Robinson2013-10-031-13/+4
