Problems solved by technology

Usually, technicians combine the audio and video files that match the audio and video files to make audio and video resources, video teaching, animation and other audio and video files more vivid. However, this method of artificially selecting audio and video effects will reduce the production efficiency of audio and video files.

Embodiment 1

[0063] see figure 1 , figure 1 It is a schematic flowchart of a sound effect acquisition method disclosed in an embodiment of the present invention. Such as figure 1 As shown, the method for obtaining the sound effect may include the following steps:

[0064] 101. The recording terminal collects the target voice signal sent by the voice actor during recording.

[0065] In the embodiment of the present invention, the recording terminal can use the MATLAB data collection toolbox in the recording terminal to collect the analog voice signal (that is, the target voice signal) through the sound card through the visualization module of voice collection and analysis. Simultaneously also collect target voice signal by recording module, save this target voice signal in the recording terminal with a certain data format (such as data formats such as WAV, MP3, AIFF, MIDI or WMA), and trigger step 102 to carry out target voice signal analyze.

[0066] In the embodiment of the present i...

Embodiment 2

[0080] see figure 2 , figure 2 It is a schematic flowchart of another sound effect acquisition method disclosed in the embodiment of the present invention. Such as figure 2 As shown, the method for obtaining the sound effect may include the following steps:

[0081] 201. The recording terminal receives a recording start instruction.

[0082] In the embodiment of the present invention, the recording terminal can receive a recording start command for triggering the voice collection and analysis visualization module and the recording module to collect the target voice signal. The recording start password may also be the click of the virtual button on the screen of the recording terminal by the voice actor received by the recording terminal. Therefore, by executing step 201, the recording is started only after the start command is obtained, which increases the utilization rate of the recording terminal, and further reduces the power consumption of the recording terminal.

Embodiment 3

[0100] see image 3 , image 3 It is a schematic flowchart of another sound effect acquisition method disclosed in the embodiment of the present invention. Such as image 3 As shown, the method for obtaining the sound effect may include the following steps:

[0101] 301. The recording terminal receives a recording start instruction.

[0102] 302. The recording terminal responds to the recording start instruction, and collects the initial voice signal sent by the voice actor during recording.

[0103] 303. The recording terminal filters noise signals lower than the noise gate in the initial voice signal to obtain a target voice signal, the target voice signal is higher than the noise gate, and the noise gate is a preset level threshold.

[0104] 304. The recording terminal analyzes the target voice signal to acquire an acoustic feature of the target voice signal.

[0105] 305. The recording terminal acquires emotion information for expressing human emotions that matches th...

Abstract

A sound effect acquisition method and a recording terminal are disclosed. The method comprises the following steps that the recording terminal is used to collect sounds of a dubbing specialist, carryout noise reduction processing on the collected sounds and then acquire clear dubbing specialist sounds; the recording terminal extracts acoustic characteristics of an intonation, a speed, keywords and the like of the dubbing specialist and matches with corresponding emotion information according to the acoustic characteristics; and the recording terminal can extract an emotion characteristic corresponding to the emotion information from the emotion information and search a corresponding sound effect from a sound effect database according to the emotion characteristic so that the dubbing specialist can select the most suitable sound effect and a synthesized video file possesses a high ornamental value. In the invention, the recording terminal can automatically acquire the sound effect according to the sounds of the dubbing specialist and making efficiency of the video file is increased.

Description

technical field [0001] The invention relates to the technical field of recording terminals, in particular to a sound effect acquisition method and a recording terminal. Background technique [0002] In audio-visual files such as film and television resources, video teaching, and animation, what people pursue is not only visual effects but also auditory effects. Audio-visual files usually require post-dubbing. In addition to the cooperation of dubbing actors, the post-dubbing needs to be matched with appropriate sound effects to create the best viewing effect. Usually, technicians combine sound effects and audio-visual files that match the audio-visual files to make audio-visual files such as video resources, video teaching, and animations more vivid. However, this method of artificially selecting sound effects will reduce the production efficiency of audio-visual files. Contents of the invention [0003] The embodiment of the invention discloses a sound effect acquisition...
