Exploring Convolution - Maliki Ramia

AudioThing is a sound design lab based in Dublin, Ireland, focused on sample libraries, audio plug-ins, and synth patches. AudioThing was founded in 2011 by composer, sound designer, and programmer Carlo Castellano and has been producing and developing sounds since then. We specialize in the development of sample libraries for Native Instruments Kontakt, audio plugins (VST, AU, AAX), and patches for various synthesizers.
