A method and a system for measuring an audio transmission delay are provided. Synchronization operation is performed on transmission of an original audio codebook to be tested between a transmitter and a receiver. A transmitter starts sending the original audio codebook to be tested to a receiver in response to sending start instruction information, and stops sending the original audio codebook to the receiver in response to sending end instruction information. The receiver starts capturing the original audio codebook from the transmitter in response to receiving start instruction information and stops capturing the original audio codebook from the transmitter in response to receiving end instruction information. The audio transmission delay is obtained based on a test audio codebook captured by the receiver and the original audio codebook pre-stored in the receiver.
