Additional Information

ForceHost is a toolchain for embedded physical modelling of audio-haptic effects for digital musical instruments. It primarily supports the TorqueTuner device, but can optionally be used with ESP32 boards supporting audio I/O, a 1-DoF servo, and network connectivity. Network connectivity is necessary so that it can be connected to other audio synthesis programs and so users can access the editor GUI through a web application. This application allows users to create haptic effects at runtime by sketching and manipulating curves representing transfer functions. Based on Faust, ForceHost is also supported by a fork of Synth-a-Modeler and can be controlled with a lower-level API called haptic1D.
