| * EFX:Pitch Shifter implementationRaulshc2018-03-187-2/+514
| | | | | | Add pitch shifter effect using standard phase vocoder, based on work of Stephan Bernsee. Only mono signal processing by now.
* | Update the multi-reverb example with improved transitionsChris Robinson2018-03-201-143/+236
| | | | | | | | | | | | | | | | This better calculates the environment coverage by correctly calculating the portal's extents, improves the panning direction when close to the portal, and applies attenuation based on contribution. Movement has changed to make the listener move back and forth between environments with a stationary source, rather than continually looping environments with a position-relative source.
* | Fix the reverb panning behavior to better fit the specChris Robinson2018-03-191-83/+38
| | | | | | | | | | | | Previously it would attenuate the response from direction opposite to the vector, whereas the property descriptions say it should simply move all reflections toward the given direction.

|
* Store the filter history in local variablesChris Robinson2018-03-142-28/+34
| | | | | Despite being marked as restrict (and const for src) to mark the pointers as being non-aliased, it seems the compiler optimizes better this way.
* Avoid using pa_stream_begin_write with PulseAudioChris Robinson2018-03-141-23/+9
| | | | | | | | | | | | | It seems to actually have a negative performance impact when the system is under load. Without having actual measurements for any potential benefits, simply go with the recommended (and previous fallback) method of allocating space for the write and passing the free method. Ideally some kind of ring buffer could be used, so rather than constantly allocating and freeing blocks of memory, it uses the same memory over again with the callback marking each one as reusable. Unfortunately the callback isn't given much information to work with, and the update size (minreq) can potentially change during playback, which complicates things.
