Adding a Radius NX AEC Coprocessor to Radius NX 4×4 or Radius NX 12×8 systems promotes the highest possible levels of clarity and intelligibility in AV conferencing and distance learning applications. System programmers optimize design performance and resource utilization by matching the number of AEC channels, number of references, and tail length to their specific requirements.
The coprocessor is available in single- and dual-core versions. Each core corresponds to a single AEC module in Composer providing up to eight channels with a single reference or up to four channels with independent references for each channel.
Wideband AEC: Optimizes far-end intelligibility
Up to 400 ms tail length: Enhanced performance in large, reverberant spaces
Adjustable background noise reduction: Optimizes far-end intelligibility in noisy spaces
Virtual, assignable, routable channels: AEC can be applied to any sources within a system and routed to any destinations
Ultra-fast convergence rate: Enhanced performance at onset of conversations and when roving microphones are in use
Highly stable adaptive filtering: No divergence during long periods of double-talk
Frequency domain NLP: Lowers far-end distortion by only removing offending spectral content
Comfort noise: Adaptively matched to natural room tone giving participants an indication that the communications channel is still active during periods of silence
