Bitrate refers to the amount of data transmitted per second during audio or video streaming. In VoIP, bitrate determines the audio quality and affects the required bandwidth for a call. Higher bitrates provide better sound clarity but use more bandwidth, while lower bitrates save bandwidth but may compromise audio quality. For example, HD voice calls use higher bitrates for crystal-clear communication, whereas low-bitrate codecs are useful in bandwidth-limited environments. Understanding and managing bitrate is crucial for maintaining call quality while optimizing network performance in VoIP systems.
