Abstract The main goal of this project was to find a way to perform spectral morphing while exploring the latent timbral space that emerges from the spectral analysis of musical sounds, and to craft new hybrid instruments. The project is split into two very well defined parts. The first is research; here we have written a collection of jupyter notebooks that address the main problems that needed to be approached such as how to perform the harmonic plus magnitudes interpolations in real-time; how to manage the result of the sound analysis into a file to be able to load it afterwards on the plugin and allow the user to build their own collection of sounds and presets; how to normalize both sounds magnitudes before the synthesis and how to transpose all the harmonics of the sound properly to be able to play the sound across every note. The second part of this project is the development of a plugin that implements all the features designed in the research part, plus designing a user interface with the proper components to allow the user to interact with the morphing engine and thus, with the generated sound. We have ended up designing and developing a plugin that accomplishes that mission, keeping in mind that it’s meant to be used professionally by producers, musicians and sound designers.
