Problems solved by technology

[0005] There are a large number of methods for estimating the loopback delay value in the prior art, each with its own advantages and disadvantages. For example, the Larson test method and the delay measurement method in WEBRTC need to measure the delay in advance, which cannot be performed in real time. In a noisy environment There will also be inaccurate or undetectable situations, and the detection accuracy is not high

Abstract

The invention relates to the technical field of audio signal processing, and discloses an audio playing control method and device, equipment, a medium and a product. The method comprises the following steps: continuously collecting real-time audio data generated by a local external input sound source in a network live broadcast process; detecting a reference signal which is pre-added into audio data of a sound source played by a local machine and is looped back by external playing, and determining a corresponding loopback delay value, wherein the reference signal is a high-frequency signal outside a human ear hearing frequency band; controlling the audio data of the sound source played by the local machine to be superposed with the loopback delay value and then to be mixed with the real-time audio data to obtain corrected audio data; and outputting the corrected audio data as an audio stream of a network live broadcast. According to the invention, audio loopback delay is calculated in real time, so that an additional operation of a user is not needed, the problem of alignment of human voice and accompaniment in network live broadcast, remote karaoke and live singing scenes is solved, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of audio signal processing, and in particular to an audio playback control method and its corresponding device, computer equipment, computer-readable storage medium, and computer program product. Background technique [0002] In the scene of karaoke and live singing on the terminal device, the device plays the music accompaniment, the anchor sings the music, and then pushes the mixed lyrics of the anchor's singing and the music accompaniment played by the device to the remote end, such as figure 1 shown. [0003] figure 1 In , the interval between the sound mixing time T4 and the collection time T3 is very short, and it can be considered that T4=T3. Since the time to collect the host’s voice is T3, and the time to play the music is T1, if there is no delay compensation or the compensation value is inaccurate during mixing, there will be vocals singing the lyrics at T1 time at the far end, while t...
