EQ Perfect is a revolutionary EQ ear trainer app. Unlike other EQ training apps where you can only choose from few pre-defined options, EQ Perfect's way of training can be immediately applied to your production workflow. We have developed our new EQ ear trainer app which contains a real parametric EQ, and a comprehensive list of lessons to build your EQ skills step by step. Because you are learning with a real parametric EQ, the workflow is just like how you would later use an EQ in your favorite DAW: FL studio, Ableton, Studio One, Logic Pro or a VST plugin such as FabFilter Pro Q 3. You will learn every aspect of a parametric EQ, including how does different frequencies sound, how much gain to apply, how steep is your EQ curve and what shape should you use. Along your journey of EQ training, we present you an overview of your performance in different aspects of the EQ skills, where you can easily spot your weaknesses and choose lessons accordingly to turn them into your strengths. The app comes with a set of FREE songs to train your EQ skills on, ranging from vocals to EDM. It is perfect for amateur music producers and mixing engineers to pick up EQ skills.
