This bachelor's thesis deals with design and construction of programmable digital audio signal generator from the field of audio electronics and its peripheral interface for controlling individual parameters. The implementation uses a powerful Teensy 4.1 Development board with i.MX RT1062 microcontroller and a low-power stereo codec SGTL5000 manufactured by NXP. Individual parameters are controlled using rotary and sliding potentiometers, buttons, switches and a rotary encoder. Individual chapters deal with theory relevant to the given topics and the subsequent explanation of its specific application. Control functions created for various parameters of sound synthesis are also briefly discussed.
