Automatic blank audio filling system and method

Abstract

The invention provides an automatic blank audio filling system and method, and relates to the technical field of audio signal delay starting, and the system comprises an audio storage module which isused for storing a plurality of pre-recorded audio contents; an audio filling module which comprises an audio selection sub-module for a user to select audio content from the audio storage module as embedded audio and acquire audio duration of the embedded audio; and an audio processing sub-module which is used for processing the embedded audio according to an externally input delay instruction containing the delay duration and the audio duration, so that a duration difference value between the delay duration and the playing duration of the embedded audio is smaller than a preset blank time threshold, and playing the processed embedded audio to automatically fill the blank audio. The invention has the beneficial effects that in the broadcast real-time broadcast process, delay processing can be entered and quitted at any time, no sound blank or tone characteristic change is caused to broadcast signals, and the continuity of the broadcast signals and the low perceptibility of audiences are kept.

Description

technical field [0001] The invention relates to the technical field of audio signal delay start, in particular to an automatic blank audio filling system and method. Background technique [0002] The delay device is a kind of equipment often used in the process of live broadcasting. It is an indispensable and important link in the broadcasting signal chain. It mainly allows the host to understand the situation of the scene before broadcasting to the outside world. It is used to dispose of inappropriate audio on the spot before it is broadcast to the outside world, so as to ensure the safety of the content during the live broadcast of the radio program. [0003] In the process of switching from the non-delay mode to the delay mode of the traditional delayer, there must be a silent transition signal with a length of delay time. This is formed by the hardware design principle of the delayer, because at this time It is the operation of writing the input signal to the memory and...

AI Technical Summary

Problems solved by technology

It takes a long time to set up the delay, and it is impossible for the user to enter the delay state immediately after turning on the delay, which will easily cause inconvenience during use

It is almost impossible to meet the needs of entering and exiting the delay at any time during the broadcasting process of 7x24 hours
