Device for controlling multi-channel sound signal volume adjustment in mobile device sound mixing device

Abstract

The present invention provides a method for regulating the sound volume to a plurality of audio signals in the sound mixing process of an audio mixing device of a mobile apparatus. The sound volume regulating coefficients of J audio signals in L audio signals are respectively controlled to lead to that the sound volume of the audio mixing signal obtained after the final regulation to L audio signals. The method obtains the sound volume of L audio signals according to the predetermined condition and determines whether the sound volume of the audio mixing signal exceeds the predetermined threshold value. If the sound volume of the audio mixing signal exceeds the predetermined threshold value, the sound volume regulating coefficients of J audio signals in L audio signals are respectively regulated according to the predetermined regulation to lead to that the sound volume of the audio mixing signal not exceed the predetermined threshold value. The invention also provides a control device which regulates the sound volume of a plurality of audio signals in the sound mixing process of an audio mixing device of a mobile apparatus. Through the invention, the sound volume of a random audio signal or a plurality of random audio signals can be regulated according to the requirement of the user thereby realizing better effect (such as Karaoke).

Description

technical field [0001] The present invention relates to a mobile device, such as a mobile phone, especially a control method and a corresponding control device for a sound mixing device in the mobile device to adjust the volume of multiple sound signals during the sound mixing process. Background technique [0002] At present, mobile devices with music playback functions, such as mobile phones, personal digital assistants (PDAs), portable multimedia players (PMPs), multimedia audio-visual center platform (PMC) products, MP4 players, handheld computers, etc. Popular, and due to the needs of some users who like karaoke or pursue new trends, mobile devices with karaoke functions are also widely used gradually. On the one hand, many businesses improve the competitiveness of their products by providing mobile devices with karaoke functions; on the other hand, users also satisfy their own needs for singing karaoke to some extent. [0003] Although many styles of mobile devices wi...

Problems solved by technology

[0004] In the Chinese patent application with the application number "200610117217.6" (a method for providing a sound mixing function for a mobile device and a corresponding device), a device for realizing a sound mixing function in a mobile device is clearly proposed, so that the real Realized the karaoke function in mobile devices, but this patent application did not solve the problem of adjusting the volume well, and this problem will affect the effect of karaoke

For example, in many cases, the user wishes to lower the volume of the original singer, and at the same time increase the volume of the singing voice (or the volume of the singer) and the accompaniment sound. However, when the volume of a certain sound signal is increased, the total volume may Exceeding the maximum threshold of the mixing device in the mobile device, which will cause sound distortion and affect the effect of singing

[0005] At present, there is no solution to adjust the volume of one or more sound signals in the mixing device of the mobile device. It is necessary to propose a technical solution to solve similar problems
