Unison is a real-time signal processing operating system which is ported to SoC hardware and generally configured. As such, it requires more customized I/O solutions for complete OEM applications. As with iZoom! and DSPnano, all defects which are known can be searched and all forum support is included without cost. All Unison use includes two hours of support per year. After these hours are exhausted, further additional support hours may be purchased for each type of response and communication mechanism at current list prices.
