This software is available with our T1 E1 product platforms, including USB T1 E1 Analyzer, Universal T1 E1 Cards, and The above features have been incorporated into DSP operators within our Windows Client Server (WCS) software.
Introduced by slowly morphing the impulse response coefficients in a predetermined manner. The echo path can be specified to mimic a "small room", a "car", a "medium size conference room", etc. In effect, the echo path can be made to vary in a manner similar to the real world. GL has simplified the process considerably by modeling the acoustic echo path and dynamicallyĬhanging its characteristics. In the past, modeling and replicating acoustic echo has been quite complicated often requiring a sound chamber, The leakage from Rout to Sin is due to the acoustic echo. Rin is the source signal (from the far end), which goes through Acoustic Echo Canceller (AEC)Īnd Sout is the echo cancelled signal, which comes out of AEC. The module, which includes AEC, Rin, Rout, Sin and Sout, can be a Sound Card, a Mobile Phone, a Regular Phone, an Rout and Sout are captured and processed. Rin and Sin files (stimulus and echo) are prepared byĪutomated AEC Test software in accordance with user inputs. Hardware or software to perform Acoustic Echo Canceller testing. The Automated AEC Test Software uses GL Communications' T1/E1 Analyzer products and the customers AEC Screenshot of Automated Acoustic Echo Cancellation Test Software for E1 To perform acoustic echo cancellation testing in accordance with ITU-T Specifications, G.167 (03/1993) and P.340 (05/2000). GL's Automated Acoustic Echo Cancellation (AEC) Compliance Test Software (PKB081) is a feature rich application used Acoustic echo, unlike lineĮcho, is dynamic during a call as people and speakers move about. This will disturb the far end speaker as they hear their own voice but delayed.Īcoustic echo cancellers (AEC) are used in phones or in the network to minimize this distortion. Output is fed back to the microphone input.
Acoustic echo is a common phenomenon that is encountered in many types of phone calls.
