Here is a link to an article which explains how the IX platform is different than and exceeds the capabilities of the AX platform, which it is built on.
In addition, this Signia white paper further explains how the AX platform was augmented to develop of the IX platform:
“The new RTCE technology is developed on top of the Augmented Focus processing (split processing) . . , (which) enables separate processing of speech and noise by splitting the incoming noise into two different streams.
“In IX, controlled by advanced sound analysis, RTCE adds three separate focus streams to the split-processing focus stream in the front hemisphere.
“. . . The analysis involves the processing of 192,000 data points per second.
“. . . As the focus streams are constantly adapting their position, width, and level of enhancement, refreshing 1,000 times per second, they will adapt immediately to the conversation layout . . .”
