About Equalizer314
To start off there is really no "free" and/or "open source" alternative to Wavelet and Poweramp EQ that pairs the full DynamicsProcessing API with real audio-visual feedback, and I felt like after using both of those apps among other various EQ apps that there were huge shortcomings in terms of the features & accessibilities they offered. When I started developing this app I wanted to have both a powerful parametric eq function with minimal permissions; this is why I choose to use both the DynamicsProcessing & Visualizer APIs as the framework for this app as you only need minimal permissions for both of them to work in tandem.
