Problems solved by technology

Bluetooth-based wireless microphones currently mainly use point-to-point connection for one-to-one connection. At the same time, based on the classic Bluetooth protocol, the maximum number of devices supported by its star network is 7, which cannot support large-scale deployment of microphone arrays.

Abstract

The invention discloses an audio acquisition method and system for multiple wireless microphones. The method comprises the following steps: sending Beacon beacon frame broadcast information to multiple wireless microphone nodes; kudging whether all the response information of the multiple wireless microphone nodes is received or not, if yes, sending recording starting information to the multiple wireless microphone nodes, and if not, continuing to receive the response information of the multiple wireless microphone nodes; and receiving the audio acquisition file of the multi-wireless microphone node. The wireless microphone array based on Wi-Fi solves the wired constraint of the existing far-field voice interaction, and at the same time satisfies the synchronization requirement of the microphone audio collection, the popularity of the Wi-Fi technology, and the Wi-Fi-based wireless microphone array technology. The application cost is significantly reduced.

Description

technical field [0001] The invention belongs to the technical field of audio collection and information communication processing, and in particular relates to an audio collection method and system of multiple wireless microphones. Background technique [0002] The current voice interaction experience has penetrated into the lives of ordinary people, and the evolution of technology has gradually extended from the interaction of entering the field to the voice interaction of the far field. The microphone array is the first ring of voice acquisition in the far-field interaction experience. The quality of the audio quality of the microphone greatly affects the experience of the back-end voice interaction, and the synchronization problem between multiple microphones is a key factor for the quality of the audio. Traditional microphone arrays transmit audio based on wired interfaces, such as usb interface, i2s interface, and spi interface. However, wired connections increasingly sh...
