MagicDeathEye is an emulation of a high-end tube compressor, available in AUv3 and interapp audio format. It is totally unique in the way it was molded from the ground up. Working together for almost a year Magic Death Eye and DDMF offer an extraordinary compressor, rich in sound, easy to control, and pleasing to the eye! We hope you enjoy it so much, it becomes your go to compressor and an indispensable mix tool. The Magic Death Eye compressor excels at vocals, bass, keys, or just about any instrument you can think of. Its gentle compression curve is also suited for master buss duties. There is a broad range of sidechain timings for just about anything a mix can throw at it. Input level controls the amount of signal that enters the intelligently modeled input transformer, tubes, and output transformer. Threshold controls the amount of signal fed to the sidechain circuit and can be thought of as the amount of compression applied to the signal. The amount of compression available is also determined by the amount of input signal present. Clicking on the "output adjust" will produce a fader with a +5dB to -20dB range acting as a master volume post compressor circuit. This is a modification to the original hardware unit in where there is only 3db of fine adjustment available. The "time" knob controls the attack and release of the compression. "1" is the fastest attack and release, "4" is the slowest. "D1" and "D2" have a fast attack, and a dual release, from medium to slow. The "attack" switch, modifies all the "time" settings with an overall Fast, Medium, or Slow. response. The "150Hz filter switch, when in the UP position, lessens frequencies under 150Hz sent to the side chain. Use this switch if you don't want low frequency material like a kick drum to pump the rest of the music. Very useful for gently compressing a whole mix. Staying true to the hardware, The bypass and power switch have the same function. Both preform a hard bypass in which the signal is not processed.

A simple but fast low-pass filter with control over cutoff frequency and resonance factor. The filter exists in an AUv3 app extension so it is available for use in any host app that supports AudioUnit components such as AUM or Cubasis or GarageBand. This app is just a delivery mechanism for the AUv3 app extension and a demo of how it works.
