ERA 4 Reverb Remover Operation


Figure 2: ERA 4 Reverb Remover - Processing Knob
This is the main control of Reverb 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.

Processing focus

Figure 3: ERA 4 Reverb Remover - Processing focus

Each of the Processing focus buttons “focuses” the dereverberation 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 the undesired reverberation take up a specific part of the frequency spectrum. You can use the appropriate setting to tell Reverb 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.

Output gain

Figure 4: ERA 4 Reverb Remover - Output Gain
Due to the nature of dereverberation, the level of the output will be significantly lower than the level of the original. This is expected as the reverb of a sound source is taking up a lot of it's dynamic range.
The output gain works as a make-up gain and allows you to adjust the level of the output signal. Reverb Remover features also an Auto option, which automatically optimizes the output level.
Unless you need to adjust the output gain manually for some reason, selecting Auto Gain is the best option. Note that Output Gain is also bypassed when the ON/OFF button is active. This is very helpful when comparing the original to the processed signals.

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

A/B switch

Figure 5: ERA 4 Reverb 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 6: ERA 4 Reverb 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 Reverb 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

Reverb 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.
