Signal processing in automotive audio digital amplifiers. Starting from basic filtering and audio routing, via algorithms for measurements and tuning, to development of sophisticated solutions for sound quality and sound stage improvement, personal zones and active noise cancellation and synthesis. Customer demonstrations. Optimization to fit designed software into cost-sensitive signal processor. Altogether this contributes to the company differentiation on the market.

Development of LED information panel for public transport stops. - Project management; - Requirements definition; - System architecture; - Hardware and embedded software design and implementation; - Technical documentation; - Preparing to mass-production (burn-in tests, non-standard manifacturing equipment design etc.).
