ERA 5 De-Clipper Operation

Processing

This is the main control area of De-Clipper. It is actually a simple toggle button which enables and disables the processing of the plugin. This is very helpful when comparing the original and the processed signals. Moreover, there are 2 types of processing. You can select between:

• Type I

• Type II

Pocessing Tip: In most cases, Type I, which is the default type of processing, is enough to detect and repair your clipped audio. For trickier cases, you may need to use Type II.

 

Processing quality

Under the main processing area, there is a 2-way toggle button to select the quality of the processing. There are 2 options:

• Standard

• High

Info: In most cases, Standard quality is enough to get great results. High quality option can improve them even more, especially in more demanding cases, but it requires more processing power from your pc.

Processing Tip: When you want to take advantage of the High Quality, but the CPU power is not enough, you can set De-Clipper in Standard quality to preview your audio and then switch to High quality to render your audio.

 

Clipping indicator

Right below the Processing Types area, there is a clipping detection indicator. It is actually a visual cue that will flash when De-Clipper detects a clipped part of your audio, indicating its clipping amount as well.

 

Output Protection indicator

Due to the nature of audio declipping, the repaired signal may exceed the amplitude limit of your host and sound like it is clipped again. Don’t worry though, this is totally expected! When this is happening, De-Clipper will inform you by flashing the OUTPUT indicator, which can be found on the left side of the plug-in. All you need to do is turn down the output gain slider, until the point where the OUTPUT indicator stops flashing.

Output gain

The level of the output signal can differ from the level of the original signal. Use the Output Gain slider by keeping an eye on the Output protection indicator to adjust the level of the output signal. This way you can be sure that the repaired signal is not exceeding your host’s amplitude limit.

Tip: Note that the Output Gain is bypassed when the ON/OFF switch is set to OFF. To compare between the processed and the unprocessed signals, use the De-Clip button of the Processing area.

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

 

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 Quality Mode) 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

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 De-Clipper 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

De-Clipper 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.

 

Quick Info Button

Right above the main processing area, you will find the Quick Info button. Enable it and hover the mouse over any control of De-Clipper. A pop-up window will appear in the middle of the plug-in, containing helpful information and tips for each control.

Info: To hide the pop-up window, just click on the Quick Info button once again.
