ECHODamp is a multi-channel audio mixer and echo controller designed primarily for the high-bandwidth, musical videoteleconference (VTC) environment. Its intuitive and easy-to-use controls work with nearly any hardware audio interface that supports CoreAudio on the Macintosh or MME, DirectSound, or ASIO on the Windows platform. Unlike other echo cancellers that use Acoustic Echo Cancellation (AEC)—which drastically alters the frequency content, making the audio unsuitable for musical applications— ECHODamp uses a sophisticated, dynamics-based algorithm to control echo without altering the frequency content.
