Today the Sjöbjörn studio has a mixing console controlled by a PC with outdated software and hardware technology. The hardware requires an ISA-bus to work at all and thereby limits the upgrades that can be made to the computer. The software runs in a DOS environment and has not been updated for a long time as well. This makes working with the mixing console more difficult then it has to be and new features are hard to implement. In this thesis I have developed new hardware so that a more powerful computer can be used which hopefully will allow for a more user friendly interface and make it easier for future upgrades and additions. The thesis presents a solution on how to upgrade the system all the way from the PCcommunication to the hardware designs. The project was based around the Microchip PIC18F4550 microcontroller for the hardware and the Visual Basic.NET programming language for the PC software.

The presented work deals with the issue of digital mixing console. The main focus is on the design of sub-circuits for the digital mixer and the construction into the 19 "rack unit. The thesis presents a detailed description of individual parts and their use. Thesis also includes complete device designs, including a power supply and additional circuits.

This thesis describes the design and implementation of a software for digital mixing console built on the Windows platform. This software is designed to offer real-time multi-channel audio processing using multiple input and output units, signal routing between these units and insertion and management of VST plug-in modules. The software uses an audio interface connected with ASIO technology. The thesis is divided into several applications. Main application which computes audio samples and allows insertion and management of plug-ins is programmed in C++ using JUCE technology. This application can be controlled with its own local graphical interface or with web control interface, which is programmed in TypeScript with the use of React technology. Web interface allows user to control VST plug-in modules with its own custom implementation of plug-in control.
