Professional Skills and Practical Experience of Vocal Cancellation in English Dubbing Materials

Sound elimination—the key to improving dubbing quality As voice dubbing practitioners, we all know that a perfect voice dubbing work needs soft, clear and natural sound, and the most important factor is the quality of human voice. Since this is so important, how to improve the quality of human voice? This article will introduce the professional skills and practical experience of vocal elimination in English dubbing materials, and solve this problem for you. Understand the principle of technology - the essence of human voice elimination Let's first understand what sound cancellation technology is. Sound cancellation technology is a digital signal processing technology. Its basic idea is to separate the desired signal and background noise, eliminate the background noise, and obtain a clearer sound. The essence of sound elimination is to make the signal-to-noise ratio of the target audio higher and eliminate other interfering sounds through filtering, denoising and other methods. Audio Cleaning - Basic Techniques For dubbing practitioners, audio cleaning is an indispensable step in order to obtain clear and natural vocals. Audio cleaning mainly includes: noise reduction, impurity removal, equalization, compression, gain, etc. These techniques are described in more detail below. Noise reduction—choose the appropriate elimination method according to the type. Noise reduction is the most basic step in audio cleaning. Common methods include: low-pass filtering; high-pass filtering; medium-pass (band-pass) filtering; selective noise reduction, etc. Only by choosing the appropriate noise reduction method for different noise types can better results be achieved. Impurity removal—removing background noise and restoring clear voices Impurity removal processing is the most important method to eliminate noise in the human voice. Generally, background noise will be removed, such as air conditioner noise, TV sound, etc. There are mainly several methods for removing impurities: high-pass filtering, noise reduction, etc. Equalization—to make audio more pleasing to the ear Equalization processing refers to adjusting the amplitude of the audio signal in the frequency domain to make the sound of each frequency band in the audio more balanced and make the listener more comfortable and happy. Compression - for a more natural volume balance Compression is the surprise of compressing the dynamic range to make the volume more even and natural and avoid unexpected mood changes. In audio cleaning, compression is used to keep different sounds in relative balance. Gain——Increase the volume and restore the authenticity of the sound. Gain is the operation of increasing the volume of the human voice in the audio after cleaning. However, too much gain will affect the sound quality, so it should be adjusted according to the actual situation. Techniques for vocal cancellation in special environments The complexity of vocal cancellation depends on the signal-to-noise ratio of the main noise components relative to the target speech. When the human voice environment is noisy and complex, it becomes more and more difficult to eliminate noise, and some techniques are needed to improve efficiency. Vocal Interference Removal Tips The increasing amount of vocal interference complicates audio cleaning and requires a few tricks to remove these noises easily. Selection of noise reduction software and problem solving If you want to eliminate sound, you will find that there are many noise reduction software to choose from, but many software often have some problems, such as poor effect, stuttering and so on. How to solve these problems? This section will bring you the solution.
