Learn how Phausto, a Pharo-based library and API, makes DSP programming accessible through Pharo's pure object-oriented model, minimal syntax, and dynamic live environment. By harnessing the power of an embedded Faust compiler, Phausto provides full access to Faust's extensive libraries and exporters, enabling the rapid development of audio tools. We'll focus on its Cmajor exporter, demonstrating how to create a plugin and use it into a DAW using the Cmajor wrapper plug-in. Additionally, we'll explore GPU-powered real-time inferencing for audio applications with NeuralAmpModeler.
