G.711 and G.726 are examples of what?

G.711 and G.726 are classified as audio codecs, which are essential for encoding and decoding audio data. Specifically, these codecs are used in telecommunications to compress and transmit voice signals efficiently over networks.

G.711 provides high-quality audio by using a PCM (Pulse Code Modulation) scheme, typically compressing audio at a bitrate of 64 kbps. On the other hand, G.726 is a more bandwidth-efficient codec that compresses audio using adaptive differential PCM (ADPCM), allowing for variable bit rates such as 16, 24, 32, and 40 kbps.

Both of these codecs are particularly important in Voice over IP (VoIP) applications, where minimizing bandwidth while maintaining audio clarity is crucial. Understanding their role as audio codecs highlights why they are specifically designed for processing voice signals rather than video or image data.
