Résumé du poste

Arturia in Grenoble invites an internship to study state-of-the-art methods for modeling Voltage Controlled Filters (VCF) in synthesizers. You will compare iterative solvers and machine learning approaches after analyzing the underlying ODEs and zero-delay feedback concepts.

The work will target the wave-digital domain and a case-study VCF, with 5–6 months on-site in Montbonnot-Saint-Martin. Master’s or final-year engineering students with DSP knowledge and Python/C++ skills are preferred.

Qualifications

• Master’s degree or final-year engineering internship is required.
• Strong DSP knowledge and interest in analog modeling.
• Experience with Python and/or C++ is valued.

Responsabilités

• Study state-of-the-art methods for modeling Voltage Controlled Filters (VCF).
• Test iterative solvers (Newton-Raphson, Steffensen, Rosenbrock-wanner) and ML approaches.
• Generalize results to the wave digital-domain VCF case-study and compare outcomes.

Description du poste

Voltage controlled filters (VCF) are essential elements of any synthesizer. Their Virtual Analog

models often need to use zero delay feedback methods which can have a high computational cost. In this internship, you will be tasked with studying state-of-the-art methods for modeling Voltage Controlled Filters (VCF). After a deep study of the electrical circuit, several approaches will need to be tested. First, the use of iterative solvers to solve the ordinary differential equation (ODE) such as Newton-Raphson, Steffensen, Rosenbrock-wanner… A deep comparison between their accuracy and their performance will be expected. Previous work in our team showed that Machine learning methods could replace the use of iterative solvers, for instance in the wave digitaldomain. This work will need to be generalized to the case-study VCF of this internship, and compared to the iterative solvers results.

_Internship Objectives:

• Study of use-case example of a VCF which require zero-delay feedback modeling (Sh-101
• Test and compare a set of different non-linear solvers, from iterative to machine learning

solutions

Profile required

• Master’s degree or Engineering school internship (final year)
• Strong knowledge in general DSP. Experience in Virtual Analog modeling would come in

handy.

• Good knowledge in electrical engineering.
• Experience in Python programming. Some experience in C++ would be a plus for a real-time implementation.
• Good command of English, as the team is international and discussions are mostly done in English.

_Conditions:

• 5 – 6 months

_Location: Grenoble (Montbonnot-Saint-Martin), accessible by public transportation.

we value diversity in our workforce and are committed to equal opportunity and inclusion. This position is open to everyone.
