Analysis and resynthesis of real instruments using Pure Data and the MKMR library

Abstract

In this experience report, I present my method for synthesizing realistic sounding instruments. Starting from the analysis of a marimba sample to how to recreate it using additive synthesis while reducing the number of objects, memory and CPU load. This synthesized model only uses pd vanilla objects, allowing an ease of implementation with projects using libpd. The instrument detailed in this article and many more are part of my open-source library: mkmr. This repository is a compilation of vanilla made abstractions with different categories such as: oscillators, filters, effects, instruments, waveshapers, sequencers, etc.
