Abstract

The invention relates to a transmission system using audio as digital signal encoding and decoding and a transmission method thereof. The transmission system comprises a first audio processing device,a second audio processing device and an analog audio signal connection device, and the audio signals are transmitted between the first audio processing device and the second audio processing device through the analog audio signal connection device. The first audio processing device converts a digital signal into an analog audio signal and outputs the analog audio signal to the analog audio signalconnection device, the second audio processing device receives the analog audio signal from the analog audio signal connection device and converts the analog signal into the digital signal supportingfast Fourier transform operation, and the analog audio signal connection device is a standard 3.5 mm connector or an analog interface in other forms.

Description

technical field [0001] The invention belongs to the transmission field of multiplexed analog and digital communication interfaces between different audio devices, and in particular relates to a transmission system and a transmission method using audio as digital signal codec. Background technique [0002] The current technical solution for analog data transmission between different audio processing devices can only transmit audio analog data, and cannot transmit custom digital signals at the same time. [0003] The current technical solution generates audio clips of different frequencies by the sending end and stitches them into an audio data stream. After receiving the audio stream, the receiving end parses it according to the frequency information of the audio stream. / or the duration of the end time relative to the pre-agreed reference time is pre-agreed. Data transfer flexibility is poor. [0004] At present, there are very few means of audio communication. Therefore, ...
