Acoustic Echo Cancellation, also called AEC, is an essential part of providing speech enhancement (or voice quality enhancement) to any telephone communicati In real world echo cancellation we also need to deal with problems like freezing the adaption when both people are talking at once (double talk). In this case the ec signal is made up of the echo plus the “near end” talker’s speech rather than just the echo by itself. SoftEcho is an Echo Cancellation (EC) software plug-in for end-user voice applications up to 16 channels. Powered by Octasic's innovative and industry-proven Acoustic and Line EC algorithms, SoftEcho ensures excellent sound quality in all audio environments, even those with disruptive background noise. In an ideal situation then, echo cancellation alone will be used.

High Performance Echo Cancellation (HPEC) The HPEC module is a carrier-grade software echo canceller for use with Sangoma telephony cards that do not include hardware echo cancellation. Download HPEC Andrea Electronics is a leading developer and supplier of Digital Array Microphones, USB computer Microphones, Beam Forming/Noise Reduction and Echo Cancellation Software, that improves the performance of applications such as: computer speech recognition and Voice over the Internet (VoIP) video conferencing. Zoom Room software audio processing includes echo cancellation, noise reduction and automatic gain control. If the microphone in use includes built-in audio processing, this setting can be disabled to avoid the Zoom Room audio processing interfering with the built-in audio processing. Xorcom has designed a hardware echo canceller module for its award-winning Astribank telephony interfaces and Asterisk-based IP-PBX appliances. The module provides a high level of echo cancellation and voice enhancement while reducing load on the CPU, as compared to OSLEC, the software-based echo cancellation solution provided in the standard Acoustic echo cancellation is about removing unwanted echos from a signal sample. A typical application is a conference system as illustrated in Figure 2.4.

In fact, we turn off AEC software when we use an ECM, so that the sound doesn’t go through two rounds of echo cancellation and introduce an unnatural latency into the conversation. SoliCall’s unique noise reduction software includes an innovative NOISE FIREWALL ™ for contact centers, a versatile echo cancellation software and a unique noise reduction technology. With SoliCall’s noise cancellation software you can easily improve audio quality in any type of phone call. One of the key features on DSP units is Acoustic Echo Cancellation (AEC). This feature is not usually found in other types of mixers, and is an absolutely essential function in some situations. AEC is required when a system is used for two-way conversations between locations such as commonly occurs during audio-only phone calls and videoconferences.
