Cart Line Echo Canceller (Software Codecs)
VOCAL Technologies, Ltd.
Description
VOCAL's line echo canceller is compliant with ITU-T G.168-2007 and optimized for high performance on many TI DSP architectures. To address shortcomings in the G.168 standard, VOCAL performs rigorous test sets in addition to the standard ITU test suite to guarantee world-class performance under harsh conditions. Characteristics include rapid convergence, double talk detection, low divergence during double talk, works with fax and low speed voice-band data transmission, ANSam auto-disable, tone rejection, narrow band stability, and NLP with noise fill.
