episode 286: Software Analog Effects
Guest: Julian Parker Host: Markus Voelter Shownoter: Jochen Spalding
Effects devices are essential for electric guitars and keyboards because they shape sound and make it interesting; many classic devices exist. However, those are rare and/or expensive, plus, even if they are not, carrying them around on a tour costs money. This is why these hardware devices are simulated in software, and distributed as plugins for audio software. Native Instruments is a manufacturer of such software analog effects packages. In this episode I chat with one of their engineers, Julian Parker, about how this software simulation of the electronic hardware is done.
