Machine noise, like fans or air conditioners, are higher frequencies, but, generally, defined by some very specific pitches. Not so the human voice. Pitch and volume range wildly.
Worse, the frequencies of the talking you want to remove are, essentially, the same as the frequencies of the talking you want to keep. Removing voices behind your actors can be very, very difficult. After all, hearing the sound of the location is why we went to that location in the first place. If you want to remove noise, your best — and sometimes only — option is to re-record your actors in an acoustically-treated room.
However, syncing these new recordings with the originals is time-consuming and tricky. This first option is available in the Multitrack mix. The good news is that it is, essentially, automatic. Higher settings can prevent clicks from being repaired, as they might not be actual clicks.
You want to reject as many detected clicks as possible but still remove all audible clicks. If a particular sound becomes distorted, then increase the setting to keep repairs at a minimum. The fewer repairs that are needed to get good results, the better.
Determines the FFT size used to repair clicks, pops, and crackle. For some types of audio, however, you might want to enter a specific FFT size from 8 to A good starting value is 32, but if clicks are still quite audible, increase the value to 48, and then 64, and so on. The higher the value, the slower the correction will be, but the better the potential results. If the value is too high, rumbly, low frequency distortion can occur. Fill Single Click.
Corrects a single click in a selected audio range. Otherwise, settings of to work very well for filling in single clicks. Once a single click is filled, press the F3 key to repeat the action.
You can also create a quick key in the Favorites menu for filling in single clicks. Pop Oversamples Width. Includes surrounding samples in detected clicks. When a potential click is found, its beginning and end points are marked as closely as possible. The Pop Oversamples value which can range from 0 to expands that range, so more samples to the left and right of the click are considered part of the click. If corrected clicks become quieter but are still evident, increase the Pop oversamples value.
Start with a value of 8, and increase it slowly to as much as 30 or Specifies the number of samples between separate clicks. Possible values range from 0 to To independently correct extremely close clicks, enter a low value; clicks that occur within the Run Size range are corrected together. If the Run Size value is too large over or so , then the corrections may become more noticeable, as very large blocks of data are repaired at once. If you set the Run Size too small, then clicks that are very close together may not be repaired completely on the first pass.
Pulse Train Verification. Prevents normal waveform peaks from being detected as clicks. It may also reduce detection of valid clicks, requiring more aggressive threshold settings. Link Channels. Processes all channels equally, preserving the stereo or surround balance. For example, if a click is found in one channel, a click will most likely be detected in the other. Detect Big Pops. Removes large unwanted events such as those more than a few hundred samples wide that might not be detected as clicks.
Values can range from 30 to Note that a sharp sound like a loud snare drum hit can have the same characteristic as a very large pop, so select this option only if you know the audio has very large pops like a vinyl record with a very big scratch in it. If this option causes drum hits to sound softer, slightly increase the threshold to fix only loud, obvious pops.
Ignore Light Crackle. Smooths out one-sample errors when detected, often removing more background crackle. If the resulting audio sounds thinner, flatter, or more tinny, deselect this option. Performs up to 32 passes automatically to catch clicks that might be too close together to be repaired effectively.
Fewer passes occur if no more clicks are found and all detected clicks are repaired. In general, about half as many clicks are repaired on each successive pass.
A higher detection threshold might lead to fewer repairs and increase the quality while still removing all clicks. The most common application addresses power line hum from lighting and electronics. But the DeHummer can also apply a notch filter that removes an overly resonant frequency from source audio. To quickly address typical audio problems, choose an option from the Presets menu.
Sets the root frequency of the hum. Sets the width of the root frequency and harmonics above. Higher values affect a narrower range of frequencies, and lower values affect a wider range. Number of Harmonics. Harmonic Slope. Output Hum Only. There are five processing focus buttons. Each of the Processing focus buttons focuses the noise suppression process on specific parts of the signal's frequency spectrum. All frequency focus. Use this to apply the same processing to the full frequency spectrum of the signal.
Hi frequency focus. Use this to focus processing on the high-end range of the frequency spectrum. Use this focus to process more on the high and low-end range of the frequency spectrum of the signal and less on the mid range. Mid frequency focus. Use this option to apply focus on the mid-range of the frequency spectrum of the signal and less to the high and low-end range. Low frequency focus.
This option focuses processing on the low-end range of the frequency spectrum. Applying the dereverberation effect could result in lower levels of output in comparison to the orginal audio due to reduction in dynamic range. The output gain works as a make-up gain and allows you to adjust the level of the output signal. Use the slidrer to adjust gain manually. Alternatively, you can enable automatic adjustment of gain by enablig the Auto Gain checkbox. This could be unwanted hum and hiss, fans, air conditioner or any other background noise.
You can control the amount of noise reduced using a slider. Applying the DeNoise effect could reduce the level of the output signal and make it lower than the level of original audio.
Use the Gain slider to control the amount of output signal. Enable the Output Noise Only checkbox to listen to the removed noise in isolation. The processing focus for DeNoise effect is similar to DeReverb effect. For more information, see Processing focus. This effect greatly lowers the amplitude of a frequency range if it falls below an amplitude threshold called the noise floor. Audio in frequency ranges that are louder than the threshold remain untouched.
If audio has a consistent level of background hiss, that hiss can be removed completely. To reduce other types of noise that have a wide frequency range, try the Noise Reduction effect. See Noise Reduction effect Waveform Editor only. Capture Noise Floor. Graphs an estimate of the noise floor. The estimate is used by the Hiss Reduction effect to more effectively remove only hiss while leaving regular audio untouched. This option is the most powerful feature of Hiss Reduction.
To create a graph that most accurately reflects the noise floor, click Get Noise Floor with a selection of audio that contains only hiss. Or, select an area that has the least amount of desirable audio, in addition to the least amount of high frequency information.
After you capture the noise floor, you might need to lower the control points on the left representing the lower frequencies to make the graph as flat as possible. If music is present at any frequency, the control points around that frequency will be higher than they should be. This information helps you distinguish hiss from desirable audio data. The actual value used to perform hiss reduction is a combination of the graph and the Noise Floor slider, which shifts the estimated noise floor reading up or down for fine-tuning.
