# What is FREQUIA?

**FR**<mark style="color:red;">**EQ**</mark>**UIA**® is the culmination of over a decade of research into critical listening and technical ear training. The result is an **expert** **technical ear training application** that was painstakingly designed to be both advanced and simple to use; everything you need and nothing you don’t.

FR<mark style="color:red;">EQ</mark>UIA trains you to develop an internal reference (long-term memory) for the sound of a multitude of filters and equalizers applied at various frequencies, gain levels, and Q values. **By training with FR**<mark style="color:red;">**EQ**</mark>**UIA, you'll learn to identify and correct problem frequencies faster, sculpt sounds with more accuracy, and hear increasingly subtle differences in timbre.**

Forget answering random questions, **FR**<mark style="color:red;">**EQ**</mark>**UIA's** [**Adaptive Training**](/frequia/advanced-training/adaptive-training.md) **mode provides personalized training based on your unique performance** **profile**. You'll save hours by spending less time training on what you know and more time training where you need to improve.

We trust you’ll enjoy using FR<mark style="color:red;">EQ</mark>UIA as much as we enjoyed creating it.
