Accusonus - ERA Voice Leveler

ERA Voice Leveler is a one-knob audio effect plug-in that automatically balances the level of your audio. Based on the multi-patented accusonus algorithms, ERA Voice Leveler simply works and allows your audio to have consistent levels throughout a recording, especially on speech and dialogue cases. 


  • Single knob operation
  • Simple and streamlined user interface
  • Automatic level normalization
  • Input/output waveform view
  • Precision-grade audio repair functionality
  • Uncompromised sound quality
  • Resizable UI

ERA Voice Leveler Operation

This is the main control of ERA 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 control 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 modes

On the left side, below the processing knob, there is a 2-way toggle button. Use it to select the processing mode. The available modes are:

  • Normal
  • Tight

The processing mode affects the way Voice Leveler analyzes your signal and adapts the internal processing parameters. Use the default,Normalmode for a more natural processing, or use theTight mode to make the processed signal more pronounced.
On the right side, there is theEmphasis button. You can enable this button, to apply an automatic and smooth tonal balancing on the processed signal. This setting will add an extra presence and liveliness to the sound, but only if it detects it's needed.

Example: Do you work with podcasts? Enable the Tight mode and your voice recording will have a more focused character. If you work with background music, this setting will probably make your voice ``sit`` better in the mix.

Tip: The Emphasis button has a led indicator next to the button name. This indicator informs you when Voice Leveler detects that your audio recording is not tonally balanced and will automatically process it to fix this.

Output gain 

The audio output of ERA Voice Leveler is alwayslouder 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 theON/OFF switch is set to OFF. This is very helpful when comparing the original and the processed signals.

Waveform view

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.

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, Mode & Emphasis) independently for the A and the B setting. You can use the A/B switch to quickly compare two settings and help you in your decision.

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 ERA 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

ERA 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.
