A software program intended to acquire, process, store and analyse biological electrical signals, both in real-time and delayed time, for diagnostic applications. The signals are typically provided by electrophysiological recording/monitoring [e.g., electromyography (EMG), electroencephalography (EEG), evoked potentials (EP), bioelectrical impedance analysis (BIA)]. It may be installed in the recording/monitoring device, personal computer, or data network server. It is neither intended for continuous bedside nor intraoperative monitoring, and is not dedicated to hearing analysis.
