Audio encoding is the process of converting voice signals into digital data to transmit it over VoIP networks. It uses codecs (like G.711 or G.729) to compress audio files, making them smaller and easier to send over the internet. The choice of codec affects audio quality, bandwidth usage, and latency. High-quality codecs provide clearer sound but require more bandwidth, while low-bitrate codecs save bandwidth but may reduce audio clarity. Audio encoding is crucial for VoIP call quality, ensuring clear communication even in low-bandwidth conditions.
