The Gramophone is a speaker/musical instrument programmable with the Faust programming language. It hosts a series of sensors (e.g., accelerometers, gyroscope, potentiometers, etc.) that can be used to interact with the sound processing algorithm in real-time.

The Gramophone is based on the ESP32 TTGO T-Audio board.

The Gramophone is used at the heart of the Amstramgrame project.
