What is the primary advantage of using G.711 and G.726 audio codecs?

The primary advantage of using G.711 and G.726 audio codecs is their lower delay and less computing power requirement. These codecs are designed for real-time communication systems, such as VoIP. G.711 is known for its minimal latency, which is crucial in voice communication, allowing for near-instantaneous audio transmission. This is particularly important in scenarios where conversation flow must be as natural as possible.

Moreover, both codecs are relatively simple in their processing needs compared to more complex codecs. This means that they don’t require extensive computational resources, making them suitable for use in a variety of devices, including those with limited processing capabilities. This efficiency also contributes to lower operational costs in terms of hardware and energy consumption.

While higher audio quality might be a significant factor, G.711’s quality comes at the cost of larger bandwidth usage. The other options regarding bandwidth efficiency and enhanced sound features do not align with the primary advantages of these specific codecs either, as G.711 is inherently less efficient in terms of bandwidth compared to other modern codecs, and it doesn’t offer surround sound enhancements. Therefore, the key benefits are indeed the lower delay and reduced processing power demands, making them ideal for standard voice applications.
