Job description
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 digital domain. 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
ladder filter, SEM VCF, …)
- 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.
If you are willing to join passionate teams and a growing international company in the music
industry, send us your resume and cover letter, specifying the internship for which you apply.
