PeakEater is a free, easy to use waveshaping plugin. PeakEater lets you choose between different waveshaping functions to clip everything above ceiling level. Therefore, you can boost overall volume of your track safely without worying that some nasty peak would go above maximum allowed volume level of your DAW. It supports variours features such as multiple clipping types, oversampling and visualizations of clipping process that aims to make clipping easy and fun.

Adjusts gain level before and after processing. Input Gain is useful when you're either working with too quiet or too loud signal and Output Gain can be helpful to compensate loss of gain.

Use linking to automatically set the Output Gain level to the opposite of the Input Gain. For example, if the Input Gain value is set to +5dB then the Output Gain value will be automatically set to -5dB and vice versa.

Control your ceiling. Everything above this level would be "eaten". Build-in RMS meter would show you signal level that comes into clipper and help you set threshold.

Displays magnitude(in dB's) so you can see how peaks were eaten over time.

Shows approximated RMS that was cut("Eaten") in last 2 seconds and current clipping algorithm. Double-click on numbers to drop it to zero and force to re-calculate.

Right click on Visualizer to switch between different scales.

Choose between 6 clipping functions, from Hard clipping to different types Soft Clip(Up to Arctangent). Available clipping functions are:

• Hard
• Quintic
• Cubic
• Tangent
• Algebraic
• Arctangent

You can read more about difference between Hard and Soft clipping here and here.

Choose between 2x, 4x, 8x, and 16x oversampling to avoid signal aliasing. You can also turn off oversampling.

Note High values of oversampling may hurt CPU performance.

You can read more about oversampling here.

Bypasses all plugin's processing. Useful when you need to make side-by-side comparsion before and after processing.
