CELTalk implements a low latency VoIP application using the CELT codec. This new, free codec implements an ultra-low delay wideband audio compression algorithm, we add security, and history if required. We respect your privacy, operate peer-to-peer, pass NAT gateways, talk IPv6, and will be your fastest way to pass a message without shouting.

Currently the application is designed using KISS methodology, wanna help out? Either join the codec development team, or drop us a line!
