Laurent de Soras' HIIR library: [http://ldesoras.free.fr/](http://ldesoras.free.fr/)\r\n- Steinberg VST3 SDK: [https://github.com/steinbergmedia/vst3sdk](https://github.com/steinbergmedia/vst3sdk)\r\n- Readerwriterqueue: [https://github.com/cameron314/readerwriterqueue](https://github.com/cameron314/readerwriterqueue)\r\n\r\n# Credits\r\n- Special thanks to host vendors who have set me up with an NFR license.\r\n-

sins](https://www.deviantart.com/dantecyberman/art/Seven-deadly-sins-442680725).\r\n- Contains a slightly adapted implementation of [Jezar's Freeverb](https://github.com/sinshu/freeverb).\r\n- Contains a slightly adapted implementation of the [Karplus-Strong algorithm](https://blog.demofox.org/2016/06/16/synthesizing-a-pluked-string-sound-with-the-karplus-strong-algorithm).\r\n- Contains a verbatim implementation of [Andrew Simper's state variable filter equations](https://cytomic.com/files/dsp/SvfLinearTrapOptimised2.pdf).\r\n- Contains a verbatim implementation of [Moorer's DSF algorithm as described by Burkhard Reike](https://www.verklagekasper.de/synths/dsfsynthesis/dsfsynthesis.html).\r\n\r\nFurthermore parts of InfernalSynth are implemented based on various resources found mostly on\r\n[KVR Audio](https://www.kvraudio.com), [DSP Stackexchange](https://dsp.stackexchange.com),\r\n[Music DSP](https://www.musicdsp.org) and [DSP Related](https://www.dsprelated.com).\r\nLook for // http:// or // https:// in the source code for sources relevant to a specific feature.\r\n\r\n# How to build\r\n- Needs cmake and visual studio 2022\r\n- Source dependencies are included in the /lib folder\r\n- Clone infernal synth into /path/to/infernal\r\n- Run /path/to/infernal/scripts/build_win32.bat\r\n- If all goes well, final output is produced in /path/to/infernal/dist.\r\n\r\n# Screenshots\r\nSee screenshots for all themes:
