PADsynth is an audio synthesizer using Mammut FFT. It is an algorithm that generates very beautiful sounds, even if its idea is much simpler than other algorithms. It generates a perfectly looped wavetable sample which can be used in instruments. It easily generates sounds of ensembles, choirs, metalic sounds (bells) and many other types of sound.
I want to make this algorithm known and you are welcome to learn and use this algorithm into your projects or products (non-commercial or commercial). You will not be dissapoined by this algorithm. This page includes some public domain C/C++ sources that can be used in your projects/products.
This algorithm is implemented in ZynAddSubFX in the PADsynth module and you can download it to hear yourself how beautiful sounds it can generate. Before reading this document, I recomand to listen to all sound examples in the next category. It will give you an idea of what kind of sounds it produces.
