Problems solved by technology

[0004] In the iOS system, the native development framework integrates a wealth of video / audio processing functions, which can be used for karaoke recording. However, there is no unified plan for the specific audio processing steps, which leads to complex processing of synthesis, dubbing, and mixing in karaoke recording. Confusion is not conducive to the optimization of karaoke recording algorithms. If you want to expand new functions (such as karaoke scoring), you often need to make major changes to the source code, which is not conducive to improving development efficiency

Embodiment Construction

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0049] like figure 1 Shown, the method for K song recording of the present invention comprises the steps:

[0050] Set the mixing data source MixerNode to form the accompaniment music,

[0051] Set the IO data source IONode to obtain the karaoke sound collected by the recording hardware.

[0052] Output the accompaniment music to the IO data source IONode,

[0053] The IO data source IONode mixes K-song sounds and accompaniment music to form K-song music.

[0054] The IO data source IONode outputs karaoke music to complete karaoke playback processing,

[0055] The IO data source IONode outputs karaoke sounds to form an input data stream,

[0056] Perform input callback on the input data stream to form K song related data,

[0057] K song-related data is used as one of the input information of the mixing data source MixerNode for use by the corresponding...

Abstract

The invention relates to a method for recording karaoke songs, comprising the following steps: setting a mixing data source MixerNode for forming accompaniment music, setting an IO data source IONode for obtaining karaoke sounds collected by recording hardware, and accompaniment The music is output to the IO data source IONode. The IO data source IONode mixes the K-song sound and the accompaniment music to form a K-song music. The IO data source IONode outputs the K-song music to complete the K-song playback process. The IO data source IONode outputs the K-song sound to form Input the data stream, and perform input callback on the input data stream to form K song related data, and the K song related data is used as one of the input information of the mixing data source MixerNode for use by the corresponding functional modules. The present invention unifies the karaoke recording algorithm, can simultaneously process original singing, accompaniment singing, and accompaniment data, realizes playback while recording, reasonably arranges callback processing, has good audio processing effect, and is easy to develop, debug, and maintain.

Description

technical field [0001] The invention relates to the technical field of audio recording, in particular to a method for recording karaoke songs. Background technique [0002] The source of KTV comes from Japan. KTV is the abbreviation of Karaok TV. Karaok is a mixed name in Japanese and English. Kara means "empty" in Japanese, and ok is the abbreviation of "unaccompanied band" in English. It evolved into "Karaoke" in China. Now it is further referred to as K song. [0003] In order to meet the public's demand for K songs, more and more K song software has been released for users to use in portable devices (such as mobile phones, tablets, etc.). Its essence is free K song recording software. It can karaoke on portable devices (desktops and other devices are also supported). Integrate the user's own singing voice into the accompaniment provided by the karaoke software, and then use the software for free karaoke audio effect processing and ok audio editing, such as background...
