Bass Enhancer AUv3 plug-in — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the Bass Enhancer AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of Bass Enhancer AUv3 plug-in comes as In-App Purchase. Does your bass sound dull and lifeless? Red Rock Sound Bass Enhancer will be your choice to correct this deficiency. Bass Enhancer designed for saturation harmonics of low-frequency, it creates the effect of lower, deeper frequencies. This effect can not be created with simple equalization. Features: • ON switch — allows the user to bypass the Bass Enhancer for before/after comparisons; • LEVEL — control knob for the Level of the Input Signal; • INPUT meter — lets You monitor the output level before Bass Enhancer processing; • TIMBRE — sets the balance between Odd and Even harmonics; • FREQ — this knob simply controls where the process begins in frequency domain (for example, with a setting of 85 Hz, all frequencies below 85 Hz will have Harmonics generated by the system); • LISTEN — mute the Mix signal and Listen to the Bass signal created by Bass Enhancer; • MIX — sets the amount of Bass Enhancer enhancement added to the original signal; • H.meter — the Level meter for the Harmonics that are created; • OUTPUT meter — lets You monitor the output level after Bass Enhancer processing; • Undo/Redo; • A/B comparison; • 2x/4x/8x Upsampling; • Macro controllers; • Built-in Gain Match; • Scalable GUI.
