As a Research Intern, you’ll work on a cutting-edge challenge at the intersection of audio engineering and AI. Your goal is to help create an intelligent system that automatically optimizes audio performance in professional conference environments.

• Understand the problem space – Analyze how professional audio systems are currently configured and identify key parameters such as microphone sensitivity, equalization, echo cancellation, and feedback suppression
• Explore AI-driven solutions – Research and evaluate AI and signal-processing techniques for automatic audio optimization
• Define data strategy – Identify relevant data sources (e.g. audio signals, acoustic responses, system state, room occupancy) and design a robust data collection approach
• Design intelligent systems – Develop a concept for automated audio tuning, including model architecture, features, and learning approach (rule-based, ML, or hybrid)
• Build a Proof of Concept – Implement and prototype your solution to demonstrate autonomous audio optimization
• Test in real-world scenarios – Evaluate performance in representative conference conditions (empty vs. occupied rooms)
• Assess impact & feasibility – Analyze robustness, practical integration, and added value within a professional audio ecosystem

• You have an affinity with Digital Signal Processing (DSP) or audio processing fundamentals
• You are familiar with AI / Machine Learning concepts (e.g. supervised learning, optimization, adaptive systems)
• You have experience in programming and algorithm development (e.g. Python, C/C++, or MATLAB)
• You enjoy system-level thinking, combining data, algorithms, sensors, and control logic
• You’re interested in real-world engineering challenges, ideally within audio or embedded systems
• You have a hands-on mindset and enjoy building and testing prototypes
• You can work independently, structure your work, and clearly communicate your results

💼 What We Offer:

• A hands-on internship in an international team.
• Close guidance from experienced professionals.
• A dynamic role where your input and ideas are appreciated.
• The option to work from home one day per week.
• An internship allowance between €500 and €600 per month (based on full-time employment).
