MIRacle - Algorithmic Reverb Add-On

Vienna MIR Pro 3D comes with MIRacle – a tailor-made algorithmic reverb plug-in for sweetening and enhancing MIR Pro 3D’s (or other sources’) sound. It is derived from Vienna Suite’s critically acclaimed Hybrid Reverb, enhanced by some advanced features.

MIRacle adds artificial acoustic “flavour” to the processed output of your MIR Pro 3D projects. This is a tribute to the often-used technique of adding synthetic, “hyped” reverb on top of an orchestral recording derived from the combination of main and close microphones.

The easiest way is to use a MIRacle insert in your host’s master bus, but you will have more control if you define a separate MIRacle effects bus and route your instruments’ sends to it.

Main Controls

  • Predelay: The amount of time (in milliseconds) between the dry signal and the onset of the algorithmic reverb.
  • Length: The length of the reverb tail.
  • Density: Adjusts the complexity and richness of the reverb tail. Please note that this setting also affects CPU usage.
  • Mod Level: Controls the level of modulation in the tail. Higher values might create a sense of pitch shift in steady instruments. Helps to create a more vivid sounding decay and frequency spread. The modulation engine is turned off when setting Mod Level to 0%, and CPU usage will be somewhat lower.
  • Mod Frequency: Controls the frequency of modulation in the algorithm. Modulation frequencies will be spread out randomly around the set value.
  • X-Feed: Controls the crossfeed level from left to right inside the reverb algorithm. 0% means that an input signal only on the left channel will yield an output signal only on the left channel. 100% will produce an even distribution in the stereo field, resulting in a more consistent sound.
  • Filter Response Display: Shows the response curve and frequency analysis for the current settings. The (horizontal) frequency range is from 20 Hz to 20 KHz, the (vertical) amplitude scale displays a range of 36 dB (-18 dB to +18 dB). Drag the filter handles to graphically adjust the filter’s boost/cut and/or frequency. When adjusting the filter handle, locks the frequency; locks the gain. Double-clicking a handle resets the respective band’s gain to the default.
  • L/R Width: In stereo mode, this control enhances (or reduces) the perceived stereo width of the reverb tail. Settings above 100% will add that certain “bigger-than-life” feeling to reverbs that appear to be too “narrow”. In multi-channel operation the feature is inactive.
    For multi-channel setups there are additional controls for the rear speakers. MIRacle will automatically adapt to the chosen configuration.
  • R Predelay / Length / Damp / Volume: This section allows for the relative offset of critical parameters used for the rear channels in surround setups.
  • Speaker Setup: The display follows the chosen channel configuration of your host. Clicking one of the speaker icons will mute/unmute the reverb output of the respective channel.
