This technological proof-of-concept demonstrated a real hearing aid reprogrammable in realtime using 2d interpolation over presets. The hearing aid is the Starkey Labs behind-ear type, programmed through a HI-PRO interface.
Open Sound Control was used to link the user interface (implemented with MaxMSP) to the HI-PRO. This is accomplished with a Python server accessing the Starkey COM interface and translating that to an OSC address space.
