Even though it may sound (or look) overwhelming, once you start вЂ“ youвЂ™ll see how fast and easy audio noise reduction really is.The reason I didn't know about it sooner is primarily due to the fact that reducing recorded noise is not its only or primary function. High overlap percentages and low FFT block sizes provide the highest time resolution but take longer to process the data file. Overlap processing can be used to provide high resolution in both the frequency and time axis. The setting determines what percentage of the FFT size block of data points is re-used for the next trace. There are several different types of windows used to reduce spectral leakage when performing a Fourier Transform on time data and converting it into the frequency domain. FFT (Fast Fourier Transform) is an important measurement method which converts a signal into individual spectral components and thereby provides frequency information about the signal. In a nutshell, this can be ideal for removing unwanted, frequent sharp sounds like clicks and pops. Median filter helps you eliminate impulse noise in your footage. Now that weвЂ™ve walked through the process of applying Audio gate, letвЂ™s take a look at how Median filter works. A control that raises the level of the signal, once it has been processed, to the desired level for the next stage of the signal. A hard knee clamps down right away, while a soft knee causes the compressor to gradually kick in as the signal gets further past the threshold. Determines how the compressor responds once the signal crosses the threshold. For example, if the ratio is set to 4:1, every 4dB of signal that crosses the threshold will be compressed down to 1dB. It determines how much compression is applied. For noise elimination with an electric guitar, set the parameter much higher. The release time is key to a natural sounding audio decay. Slower times (10 ms or more) for everything else. Controls the speed of the gate opening and consider very fast attack time for percussive instruments.

The higher the threshold, the louder the sound (stronger the signal) must be to open the gate. Decibel level in which the gate opens or closes.

Gates are controlled by setting several parameters: You may want to apply gating for three reasons: In other words, you create a gate to filter the sounds in the video. Technically, when you apply Audio gating, you control when and to what degree audio passes through a channel.

This filter comes in especially handy when you work with live recordings trying to remove the unwanted sounds between passages, because it is so efficient at recognizing steady noise sources вЂ“ such as rumble, hiss, and hum вЂ“ and reducing them to the minimum.

In this instruction, weвЂ™ll show you how to reduce audio noise from your recording using VSDC Free Video Editor. DonвЂ™t rush to hit the вЂњDeleteвЂќ button, though. Sometimes footage may sound вЂњnoisyвЂќ simply because there were too many background sounds when you were recording it.
