ECHODamp

• A multi-channel audio mixer and echo controller for high-bandwidth musical videoteleconferencing

• Uses a dynamics-based algorithm rather than a frequency-based one (like Acoustic Echo Cancellation) to preserve the full frequency range of the audio signal

• Intuitive and easy-to-use controls work with any 4X4 (or larger) audio interface that supports CoreAudio on the Macintosh or MME, DirectSound, or ASIO on the Windows platform

• Available free to non-profit educational and performing arts institutions at http://echodamp.com
