True elimination of echo is critical task for PBX and other VoIP equipment. NatureDSP Linear Echo Canceller (LEC) – software product for adaptive echo cancellation for telephone circuits. NatureDSP LEC uses modern powerful IPNLMS algorithm which provides the fastest convergence time and intelligent behavior under double-talk conditions. Canceller especially designed for working with non-linear hybrids providing significant ERLE improvement. Adaptive non-linear processing (NLP) scheme eliminates residual echo without speech degradation


Features

:

• adaptive echo cancellation providing comfort conversations even in presence of high line echo (up to 128 msec)
• nonlinearity compensator suppressing remaining echo caused by nonlinear distortions in electrical or acoustic path or mechanical resonances
• antihowling filters preventing distortions due to the high level of acoustic coupling
• kernel mode compatible
  

Supported plarforms:

• Texas Instruments C64xx, DaVinci
• ARM9E, ARMv5, ARMv7
• Marvell Sheeva/KirKwood, Marvell Dove
• Tensilica
  
• x86 (Microsoft Windows, Linux)
