ERA 5 Voice Leveler Operation
This is the main control of Voice Leveler. 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.
On the left side, there is the Breath Control toggle button. A common problem in voice recordings, are the breaths of the speaker between phrases. When leveling such an audio case with Voice Leveler, it is expected that some of these unwanted breaths will be increased along with the actual voice. To avoid this, just enable Breath Control. It won’t take the breaths away, but it won’t process them at all, leading to a smoother and more balanced result.
Example: In order to describe better the Breath Control function, we are going to use an example. We processed a voice recording with Breath Control enabled and disabled and we compared them. So here we have a sample of the original recording unprocessed.
As you can see, it is a low level recording with inconsistencies between the level of the phrases. Also, as you can see, there is a long breath between the two phrases. We used Voice Leveler to make the recording louder and balanced, and as expected, the breath got louder too.
Although the result didn’t sound bad at all, we wanted to even the breath part out a little bit. So here it is after the Breath Control.
As you can notice from the image, the breath level stayed at a low level(compared to the first image) and of course sounded smoother.
Tip: For recordings with background noise, Voice Leveler will increase the noise at some level, too. This is expected! To achieve great results, use the Noise Remover plugin beforehand, as this will decrease the amount of noise and will let Voice Leveler do its magic!
On the right side, you can find the Emphasis toggle button. Enable Emphasis to apply a smooth tonal balance on the processed signal. This setting will automatically add extra presence and liveliness to the sound, only if it detects it’s needed.
Tip: The Emphasis button has a led indicator next to its name. The led will flash when the plug-in detects and repairs any drop in the tonal balance of your audio.
The audio output of Voice Leveler is always louder than the input audio because it essentially increases the level of the quiet parts of your recording to match the levels of the loud parts. The output gain allows you to adjust the level of the balanced output signal to the rest of the elements of your session.
Note that this gain is also bypassed when the ON/OFF switch is set to OFF. This is very helpful when comparing the original and the processed signals.
At the bottom of the plug-in window, you can find a waveform view. Here, Voice Leveler will show the input (with black) and output signals (with yellow) to help you quickly understand how much processing is applied and how each part of your recording is affected.
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, Mode & Emphasis) 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.
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 Voice Leveler 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
Voice Leveler 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 knob, you will find the Quick Info button. Enable it and hover the mouse over any control of Voice Leveler. 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.
