ERA 4 Noise Remover Operation


Figure 2: ERA 4 Noise Remover - Processing Knob
This is the main control of Noise Remover. Most of the time you don't have to do anything else. Just dial in the amount of processing you want and you're done! The knob values range from 0% to 100% and controls the amount of processing applied to the audio signal.

Tip: You can double-click on the control to reset it to its default value.

Processing focus

Figure 3: ERA 4 Noise Remover - Processing Focus
Each of the Processing focus buttons “focuses” the noise suppression process on specific parts of the signal's frequency spectrum. There are five buttons:
  • All-freq. focus: This option applies the same processing to the full frequency spectrum of the signal.
  • Hi-freq. focus: This option focuses processing on the high-end range of the frequency spectrum of the signal.
  • Low-freq. focus: This option focuses processing on the low-end range of the frequency spectrum of the signal.
  • Hi/low-freq. focus: This option focuses processing more on the high and low-end range of the frequency spectrum of the signal and less to the mid range.
  • Mid-freq. focus: This option focuses processing more on the mid-range of the frequency spectrum of the signal and less to the high and low-end range.

Tip: These buttons are helpful when your audio is corrupted by noise sources that take up a specific part of the frequency spectrum.

Example: Hiss, a common noise problem encountered in recordings with bad gain structure or low quality preamps, is usually concentrated in the higher frequencies. You can use the appropriate setting (in this case the "Hi-freq. focus") to tell Noise Remover to apply most of the processing on those frequencies. This will reduce processing on other frequencies and leave your main signal as natural as possible.

Hum/Buzz control

Figure 4: ERA 4 Noise Remover - Hum/Buzz control
On the left side of the plug-in, you will find the Hum/Buzz control . Enable it to focus the processing on persistent tonal noises, like the AC hum caused by faulty groundings, or the the buzz caused by a faulty cable.

Tip: Hum/Buzz control will eliminate any hum or buzz completely, but it may add some artifacts, depending on the case. We'd strongly advise to use it only when it's needed.

Output gain

Figure 5: ERA 4 Noise Remover - Output Gain
Due to the nature of noise suppression, the level of the output signal can be lower than the level of the original, noisy one. The output gain works as a make-up gain and allows you to adjust the level of the output signal. Note that this gain is also bypassed when the ON/OFF switch is set at OFF. This is very helpful when comparing the original and the processed signals.

Tip: You can double-click on a control to reset it to its default value.

A/B switch

Figure 6: ERA 4 Noise Remover - A/B switch
There might come a time where you're not sure which setting is better. Note, that you can adjust the plug-in controls (Processing, Output Gain and Focus) independently for the A and the B setting. You can use the A/B switch to quickly compare two settings and decide which one is better.

ON/OFF switch

Figure 7: ERA 4 Noise Remover - ON/OFF switch
The ON/OFF switch allows you to turn on or off the plug-in processing. When the switch is at the OFF position, all processing is bypassed and the original signal comes through Noise Remover untouched.

Tip: We suggest to use the ON/OFF switch (instead of the DAW's bypass control for the plug-in). This will keep your audio in sync with the rest of your tracks in your DAW session.

Resizing the plug-in window

Noise Remover offers the option to resize the plug-in window. This can be especially helpful if you have large or high-resolution screens or you just want to focus on a specific task. Click the zoom icon at the top right corner and choose between three settings.

Warning: Low resolution screens such as 800x600 cannot correctly display the plug-in for zoom options above 100%. Additionally, some hosts may clip the plug-in window in such low resolutions.
