Yes indeed, the project has evolved quite a bit. The main goal is to develop a modular platform for sound synthesis, recording, processing, mastering, and rendering. This is crazy ambitious, but the core components that we have to develop are actually much simpler than originally anticipated. By using this modular OTO architecture, the main audio components that we have to create are:
- A single-channel mono audio ADC based on the AK5578EN
- A single-channel mono audio DAC based on the AK4499EQ
Each of these two components will have:
- one PCB for the ADC or DAC chip and a small XMOS chip (70mm × 70mm)
- one PCB for the XLR connector and its buffer (70mm × 35mm)
- one PCB for the power supply (70mm × 35mm)
The first version of the DAC might be based on the AK4497 if we cannot get access to the AK4499EQ chip.
This will allow us to create 1 x 1 OTO "reference" bricks that have either two mono audio inputs or two mono audio outputs. From there, we will create the 4-input and 4-output bricks shown on the reference setup
by simply cramming more PCBs within (possibly taller) bricks.
