Question: What is the primary purpose of the Parametric Signal Representation Decoding process (specifically Bandwidth Extension) in the EVS codec, aside from generating represented signal components?
Option 1: To enhance overall voice signal compression efficiency by reducing transmitted data.
Option 2: To improve error correction capabilities for lost packets during transmission.
Option 3: To facilitate interoperability with non-EVS codecs in mixed network environments.
Option 4: To estimate and reconstruct missing signal regions, including noise fill and blind bandwidth extension.
Explanation: The correct answer highlights the decoder's role in estimating and reconstructing parts of the signal that are not fully represented by the transmitted data, crucial for maintaining audio quality, especially when the original signal's full bandwidth is not entirely captured or transmitted.
