Problems solved by technology

[0002] Nowadays, various mobile karaoke platforms and live broadcast platforms emerge in endlessly. Correspondingly, various Bluetooth audio devices are also more and more applied to these platforms. Attached figure 1 It shows a typical application scenario. When a singer or a network anchor wears a Bluetooth headset microphone or uses a Bluetooth microphone inserted in a headset to sing or perform a live broadcast, the singer or network anchor often needs to listen to the audio from the mobile terminal. While the music is singing or talking, the voice of the singer or network anchor is sent back to the mobile terminal, which is recorded by the mobile terminal or sent to the external network. In this case, both the downlink music and uplink voice use Bluetooth HFP (Handsfree Profile) protocol (Bluetooth Technology Alliance SIG (Special Interest Group) defines multiple Bluetooth technology protocols, including A2DP, HFP, AVRCP, etc.), there is no interaction between music and voice, and the Bluetooth HFP protocol only supports up to 16KHz monophonic sampling High-speed audio transmission, the sound quality of listening to music and returning singing voice is poor, which cannot meet the HiFi sound quality requirements, resulting in poor music experience for singers or anchors

Abstract

The invention provides a music and voice transmission operation method based on Bluetooth. Various Bluetooth audio protocols are adopted in an uplink channel and a downlink channel, and uplink or downlink audios under different Bluetooth protocols are operated, so that the quality of sound obtained by a user is remarkably improved, the interaction flexibility between music and voice is improved, and the user experience is enhanced.

Description

technical field [0001] The invention belongs to the audio field, in particular to a bluetooth-based music and voice transmission operation method. Background technique [0002] Nowadays, various mobile karaoke platforms and live broadcast platforms emerge in endlessly. Correspondingly, various Bluetooth audio devices are also more and more applied to these platforms. Attached figure 1 It shows a typical application scenario. When a singer or a network anchor wears a Bluetooth headset microphone or uses a Bluetooth microphone inserted in a headset to sing or perform a live broadcast, the singer or network anchor often needs to listen to the audio from the mobile terminal. While the music is singing or talking, the voice of the singer or network anchor is sent back to the mobile terminal, which is recorded by the mobile terminal or sent to the external network. In this case, both the downlink music and uplink voice use Bluetooth HFP (Handsfree Profile) protocol (Bluetooth Tec...
