Digital Compensation of Distortion in Audio Systems (Electronics Project)

The advancements of computational power in low cost FPGAs are giving the opportunity to implement real-time compensation of loudspeakers and audio systems.

This project aims at evaluating methods for digital compensation of distortion in audio systems. The need for expensive commercial audio systems is reduced when the fidelity of much cheaper audio systems easily can be improved by real-time compensation.

More specifically, a VHDL module is implemented to, when necessary, alleviate the problem of drastically deteriorating fidelity of the bass appearing when the input power is too high.
