Problems solved by technology

Although this method can support the transmission of multi-channel audio signals through a network cable, it is still in the state of cable link
In large-scale events such as live performances and production recordings, the laying of cables can still cause a lot of trouble for sound engineers and mixers
At the same time, the damage of the cable and the looseness of the connector will also bring irreparable loss to the quality of the audio signal
[0026] To sum up, the current transmission methods of these three audio signals have their own problems, and these problems are fundamentally insurmountable

Embodiment Construction

[0056] The invention is an audio wireless network transmission system, which uses the wireless network as a medium to transmit multi-channel digital audio signals without loss and with low delay. Such as figure 1 shown. The system mainly includes an audio signal sending unit, an audio signal receiving unit, a central control unit, and control software. The audio signal sending unit receives the audio signal from the upper-level audio equipment (such as a microphone), converts the analog audio signal into a digital audio signal, and converts it into a network data packet, and transmits it to the central control unit through the wireless network. After the central control unit receives the audio data, it restores it to a standard format audio signal, and outputs it to an audio processing device (such as a mixer or a digital audio workstation, etc.) through a corresponding digital audio signal or analog audio signal format according to user needs. ), audio processing equipment ...

Abstract

The invention relates to a system for audio transmission via a wireless network, which transmits digital audio signals via a wireless network. The system includes an audio signal transmission unit and a central control unit, wherein the audio signal transmission unit receives audio signals from a piece of upper-level audio equipment, and analog audio signals are converted to digital audio signals and network data packages transmitted to the central control unit via a wireless network. The audio data is received by the central control unit and reverted to audio signals. The system further includes a piece of audio processing equipment for storing, processing or mixing audio signals.

Description

field of invention [0001] The invention relates to a network transmission system, in particular to an audio wireless network transmission system for bidirectional and lossless transmission of multi-channel audio signals through a wireless network. Background of the invention [0002] Sound engineers and sound amplifiers face hundreds of kilometers of microphone cables and other signal cables during every theater performance. Use cables to connect the microphones to the stagebox before the performance begins, and at the same time, choose the routing of the cables so that they do not cause trouble for the movement of actors and audience. When you're done, clean up all the cables. On top of that, you have to deal with irreparable noise and distortion from cable breakage. It can be said that laying all the cables takes up more than half of the time for recording and sound reinforcement preparations, and these trivial and heavy tasks are meaningless for improving the quality of...
