AAC-LD

Advanced Audio Coding-Low Delay: Low latency advanced audio coding

Alternating Current

AEC

Acoustic Echo Cancellation: Acoustic echo cancellation. A commonly used

signal processing method in teleconferencing. Because the hands-free full-

duplex mode means that the voice signals at both ends of the call are

continuously transmitted, but the terminal transmits in the form of multicast, a

feedback loop is generated at the near end, so that the caller will hear an echo.

The process of solving this problem is called acoustic echo cancellation.

AES

Advanced Encryption Standard: Advanced encryption standard. A block

encryption standard adopted by the US federal government that replaces DES.

The advanced encryption standard is intended to perform an unclassified,

publicly available symmetric encryption algorithm. The cipher block size is fixed

at 128 bits and the key size is 128 bits, 192 bits or 256 bits.

CRC

Cyclic Redundancy Check: A process of detecting errors in data transmission.

The CRC check generates a number by complex calculations based on the

transmitted data. The sending device performs this calculation before sending

the data and then sends the result to the receiving device. After receiving, the

receiving device repeats the same operation. If the operation results of the two

devices are the same, the transmission is considered to be error-free. This

process is called redundancy check because each transmission contains not

only data but also additional (redundant) errors. Check value.
