Anti-howling audio signal processing method and device thereof

Abstract

The invention provides an anti-howling audio signal processing method and a device thereof. The anti-howling audio signal processing method comprises a step of receiving a singing request which comprises the identification of a song to be sung, obtaining a background audio signal corresponding to the identification of the song to be sung, a step of obtaining a far end reference signal and a near end input signal, carrying out howling suppression processing on the near end input signal according to the far end reference signal and obtaining a first audio signal, and a step of mixing the first audio signal and the background audio signal to obtain a second audio signal. According to the embodiment of the invention, the near end input signal is subjected to the howling suppression processing, the howling generated in a speaking amplification environment is effectively suppressed, the scene of a commercial karaoke room can be simulated really, and a user enjoys the function of karaoke at any time.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for processing anti-howling audio signals. Background technique [0002] As smart phones become more and more powerful, rich multimedia functions have become a major feature that attracts consumers. Among them, among the rich multimedia functions realized by smart phones, singing karaoke with smart phones is very popular among consumers. However, most mobile phones in the current market can only sing karaoke with earphones, and do not have the ability to play karaoke outside. OK function. [0003] figure 1 It is a functional block diagram of a karaoke system for mobile terminals in the prior art, such as figure 1 As shown, the karaoke system includes a microprocessor 10, memory 11, human-computer interaction equipment, audio processor 14, FM wireless transmitter 17, audio power amplifier 18 and left and right channel speakers; wherein ...

AI Technical Summary

Problems solved by technology

[0004] However, in the external sound amplification environment, the audio signal played by the speaker will be picked up again, and then amplified and played by the audio power amplifier to form a loop, which is very easy to generate howling, which makes the playback or recording not in the same sound field, or the playback The equipment and recording equipment must be far away, which limits the application scenarios
