During a conference call, there is generally nothing worse than hearing echo being introduced into a call. Participants will hear what sounds like good quality audio, but twice (or more) as a result of this. Conference call hardware generally has two classes of equipment: those with “echo cancellation” or without. The quality of the call can be significantly degraded on systems without the echo cancellation.
AccuConference uses state of the art DSP technology (Digital Signal Processors) that employ an echo cancellation algorithm. The result is that echo is significantly reduced during a conference call. There are always things that will introduce echo no matter what, such as putting a phone in the same room as another phone in the conference call. Telephone microphones are very sensitive and even the slightest sound can be picked up and echoed to the other phone and amplified. Cellular phones are notorious for this, as there is an inherent delay introduced with a wireless network. As a result, AccuConference recommends never having two participants in the same room, unless both are muted. The result is that the quality of the call will be the highest possible.
