BSS Audio Introduces Full-Bandwidth Acoustic Echo Cancellation Algorithm for SL Conferencing Processors

BSS Audio, a Harman International Company has introduced a new full-bandwidth acoustic echo cancellation (AEC) algorithm for its Soundweb London conferencing processors. The new full-bandwidth AEC algorithm is released with HiQnet London Architect v3.04 and can be used with existing Soundweb London AEC Input Cards and the recently-introduced Soundweb London BLU-101 and BLU-102 devices.

The existing 8kHz-bandwidth AEC algorithm is optimized for POTS, VoIP phone system, and digital phone system applications. The new full-bandwidth AEC algorithm facilitates enhanced fidelity for specific applications, while also offering a reduced processing latency. A property within HiQnet London Architect v3.04 allows users to switch between the new full-bandwidth AEC algorithm and the existing 8kHz-bandwidth algorithm. Dedicated full-bandwidth "dry" signals for local sound reinforcement or recording are offered for both AEC algorithms.

Existing installations can be upgraded to accommodate full-bandwidth content, without the requirement for additional hardware. However, when upgrading systems to HiQnet London Architect v3.04, they will continue to use the 8kHz-bandwidth AEC algorithm unless manually switched to use the new full-bandwidth AEC algorithm. Therefore, changes will not be forced upon existing systems.

New Soundweb London designs will default to using the new full-bandwidth AEC algorithm, which also gives excellent performance with POTS and VoIP systems, in addition to the accommodation of full-bandwidth content.

Iain Gregory, market manager for installed sound at Harman Signal Processing stated, "BSS Audio is new to the conferencing market but our products and algorithms have already won favor with many experienced consultants and system integrators as a direct result of live demonstrations. The addition of a full-bandwidth AEC algorithm as a software upgrade for the AEC Input Cards and the BLU-101 and BLU-102 devices brings another important conferencing tool to applications large and small."
