E4L AuraVerb

- NOTE: E4L AuraVerb is presently an unsupported device. It does not run on Apple Silicon. -

The E4L AuraVerb is a first-order spatial effect that takes a mono or stereo input signal and renders a 1st-order Ambisonics spatial reverb. The output of the device is 100% wet with a level control - no dry signal is passed through. Therefore, it is typically best to use this device in combination with an E4L Source Panner earlier in the chain, for the dry source.

The In section monitors the input level and offers a Mono/Stereo control. The Reverb section offers parameterized control over the reverb's characteristics, including the Pre-Delay Time. The T60LF and T60MF set the time for the reverberation to decay 60dB in the low and mid-frequency bands. The XYZ/W control sets a relative balance of reverberation in the side-band Ambisonics channels vs. the omni channel, which controls how "spread out" the reverb feels. The LFXO control sets the frequency at which the low and mid-frequency bands cross over, and the *HFDamp control sets a frequency at which the high-frequency band is dampened (with a decay time of half the mid-band).

The EQ section shapes the frequency response of the reverb with two bands that each specify a frequency and gain.

The Compressor section is applied to the reverberated signal, with typical compressor controls of Threshold, Ratio, Attack and Release. The meter at the bottom of this section visually indicates how much compression is being applied.

The Gate section is applied after the compression stage, with typical controls of Threshold, Hold, Attack and Release. Again, the meter at the bottom of this section visually indicates the behavior of the gate.

The Out control provides gain attenuation to the output signal. Again, keep in mind that this effect only passes the 100% wet reverberated signal.
