eqMac

System audio equalizer for macOS. Professional grade Parametric EQ & volume mixer. If you feel like your audio device (Headphones or Speaker) does not have enough Bass (low frequency) punch, or vice versa, you can adjust that using eqMac. macOS does not have a direct way to access the System Audio stream, so we use the eqMac Audio driver to divert the system audio to the driver's input stream. Then eqMac captures that Input audio stream processes it, and sends it directly to the output device. Expert EQ, unlimited bands, fully customizable (Filter Type, Frequency, Gain, Bandwidth). Volume mixer, apply different volume levels per each application. Fully customize the look and feel of eqMac by changing the User Interface Colors, Feature visibility, and arrangement. Control all aspects of eqMac through a WebSocket API. Works with any programming language that supports WebSockets.
