Designed for simple and secure connectivity applications, Espressif has introduced ESP32-C3. ESP32-C3 is a cost-effective, RISC-V-based MCU with Wi-Fi and Bluetooth LE 5.0 connectivity for secure IoT applications. ESP32-C3 attempts to address the most common needs for connected devices.

Motivated by the tedious nature of the sheet music annotation process, these three Cornell students built a system designed as a music composition assistant for composers, arrangers and musicians at all levels. Called PICcompose, this is a PIC32 MCU-based, end-to-end tool that converts raw audio from playing an instrument directly into an editable sheet music score. In this article, they describe the design and components of the system.
