Score: 7.5/10 (Innovation: 7, Technical: 9, Documentation: 8, Utility: 6)

Noaidi is an open-source FPGA-based polyphonic synthesizer that uses a Sipeed Tang Nano 20K for all audio synthesis and an ESP32 for MIDI and control. Its innovative architecture features a time-multiplexed partial pipeline and a custom control signal processor, enabling 32-voice polyphony with 8 detuned partials per voice at 96 kHz. The project is well-documented and represents a significant technical achievement in hardware audio synthesis.

Target audience: hardware developers, audio engineers, musicians, FPGA enthusiasts
