If you want a high-quality conferencing system, AEC is a necessity. This is powered by an algorithm that handles comparing and cancelling almost instantaneously, and represents an accomplishment that requires a significant amount of digital signal processing. If any of the audio matches, it immediately removes it by creating adaptive filters to prevent echo. In brief, an AEC samples audio from the far side as it comes in and compares it to audio from inputs on the near side. AEC is an effective way to prevent the recirculation of reflected sound waves in a conferencing environment, and the technology is quite remarkable. The fix for this is Acoustic Echo Cancellation (AEC). When the speaker on the near end is active with far end audio, near end microphones can pick up that audio and recirculate it, creating echo. But acoustic echo created by microphone-speaker coupling demands a more robust solution.Īcoustic echo happens in a conferencing environment where microphones and speakers are being used in close proximity. Line echo is a product of reflections down the phone line, and telephone hybrids usually successfully handle that problem.
There are two types of echo: line echo, which is easily correctable, and the much more challenging problem of acoustic echo. Bad audio can quickly derail an otherwise smooth exchange and leave participants feeling distracted and frustrated.Įcho can be a primary culprit.

Sometimes the most frustrating thing about a conference call can be the technical glitches that prevent a meeting from reaching its full productivity potential.
