Tiivistelmä
In the vast world of electronics, the applicability of microcontrollers has been increasing in the last decades. The demand for audio applications such as audio signal processing and synthesis is genuine, but solutions lack thereof. The appeal of audio interfaces is that they provide user experiences that translate into emotional feedback from humans.
The purpose of this thesis was to research and assess software solutions for an existing microcontroller on the market. The thesis analyzes existing software solutions for audio signal processing deemed specifically for audio synthesizer aspirations. The hardware for these solutions was chosen with prerequisite knowledge in the context of digital audio to minimize the risk of failure during the
thesis project.
The operating system, peripherals, and drivers were adopted from the beginning, whereas software libraries were explored during the thesis project and would be selected as part of the final solution.
A feasible solution has been used for demonstration purposes. The scope of the thesis was to synthesize a single monophonic note using the target hardware and software with the ported real-time audio software library. The result does not accredit a fully-fledged result that would be considered of production quality.
