Audio and Acoustic Signal Processing

Audio signals are electronic representations of sound waves—longitudinal waves which travel through air, consisting of compressions and rarefactions and Audio Signal Processing focuses on the computational methods for intentionally altering auditory signals or sounds, in order to achieve a particular goal.

JavaScript Session Establishment Protocol (JSEP) in WebRTC handshake

SEP is used during signalling via w3c's recommended RTCPeerConnectionAPI interface to set up a multimedia session. The multimedia session description specifies the critical components of setting up a session between local and remote such as transport ports, protocol, profiles. It also handles the interaction with the ICE state machine.

Websockets as VOIP signal transport medium

Web resources are usually build on request/response paradigm such as HTTP , SIP messages . This means that server responds only when a client requests it to. This made web intercations very slow and unsuited for VOIP signalling Long Poll involved repeated polling checks to load new server resources by itself instead of client made … Continue reading Websockets as VOIP signal transport medium
