The ERA 5 Reverb Remover Pro features a Spectral Display. The spectral display looks similar to a simple spectrum analyzer but at the same time has some smart features.
What do the colored curves mean?
The three curves show three different signals:
White: The input signal. This curve shows the level and frequency analysis of the incoming signal. This is the pre-processing signal.
Purple: The output signal. This curve displays the level and frequency analysis of the output signal. This is the post-processing signal.
Grey: This line indicates the reverb that the plugin has detected, and it represents the signal that is removed from the input signal.
What is the purpose of input and output sliders?
The INPUT and OUTPUT sliders control the level of the signal at their respective locations.
The INPUT slider controls the volume of the incoming signal. Raise the slider when the signal is particularly weak, or lower it when the signal is excessively strong.
The OUTPUT slider is designed to readjust the output volume. By default, the reverb removal process lowers the overall signal volume slightly. The Auto option, when activated will compensate for these level changes. Deactivate it, if you want full control over the output signal level.
Both sliders feature a volume meter that has an indicator for clipping on top of it. If the signal is clipped at any point during input or output, the clipping indicator will turn red and will remain red until cleared, by clicking on it.
The maximum amplification/attenuation of both sliders is ±24 dB.
Why is the Spectral Display divided into sections?
The ERA 5 Reverb Remover Pro divides the signal into processing bands. This allows for more control and/or processing fine-tuning over specific frequency areas. These bands are adjustable in various ways.
Number of bands
The default number of bands is 4. The minimum number of bands is 3, and the maximum is 6. To add a band, hover over the horizontal line of a band and click on the dotted line button that appears under it. This will create a new band inside the existing one. To remove it, simply click the X button that appears at the left of the previous one.
The boundaries of the bands can be adjusted, as shown above. The minimum distance between the band boundaries is one octave.
By using the preview button, we can hear how much sound is being removed on the current band. This is especially useful when we are trying to avoid over-processing.
By default, all the bands are linked to the Master Processing knob. If we want to maintain a set level of processing for a specific band, the Unlink button will de-couple that band from the main processing, and maintain that set level.
If no processing is desired on a specific band, the band can be bypassed using the “power” button. This will allow the signal to pass through unchanged for that specific band.
Band processing amount
Each band can have a different processing amount from the others. This is useful when targeting specific areas of interest. When reverb is more prominent in a specific frequency range, adjust respectively the band boundaries and control the band processing amount according to your needs.
