• The USAC can process different window sequences for each situation to enhance encoding or decoding.
• Overlapping frames at a folding point allows for efficient processing during mode switching.

Key Features and Innovation:

• Unified speech and audio codec (USAC) for processing window sequences.
• Encoding or decoding by overlapping frames at a folding point during mode switching.
• Improved coding efficiency by processing different window sequences for each situation.

Potential Applications: The technology can be applied in:

• Audio and speech encoding and decoding systems.
• Communication devices.
• Multimedia applications.

Problems Solved:

• Inefficient processing during mode switching.
• Low coding efficiency in audio and speech codecs.

Benefits:

• Enhanced coding efficiency.
• Improved audio and speech processing.
• Better performance in communication devices.

Commercial Applications: Title: "Unified Speech and Audio Codec (USAC) for Enhanced Encoding and Decoding" This technology can be utilized in:

• Audio and speech processing software.
• Communication devices and systems.
• Multimedia applications and services.

Prior Art: Readers can explore prior art related to speech and audio codecs, mode switching in encoding and decoding systems, and window sequence processing.

Frequently Updated Research: Stay updated on advancements in speech and audio coding technologies, mode switching algorithms, and window sequence processing techniques.

Questions about Unified Speech and Audio Codec (USAC): 1. What are the key advantages of using USAC in audio and speech processing? 2. How does USAC improve coding efficiency compared to traditional codecs?

Original Abstract Submitted

a unified speech and audio codec (usac) that may process a window sequence based on mode switching is provided. the usac may perform encoding or decoding by overlapping between frames based on a folding point when mode switching occurs. the usac may process different window sequences for each situation to perform encoding or decoding, and thereby may improve a coding efficiency.
