5. Gate and Modulation do not modify the IR so they can be automated without any problems The modules CUT GATE MOD and POS can be switched on and off They are automatically switched on as soon as you move one of the controls there There are 3 ways to move a control Move mouse up and down with mouse button pressed Turn the mouse wheel Click on the control and input the value on the keyboard IN The Input Signal AE Below the input meter the last peak level is displayed which 0 0 can be reset by clicking on it i The slider at the bottom controls the input gain The slider above sets the crosstalk that mixes a part of the input signal from the left to the right channel and from the right to the left channel When using a 4 channel true stereo IR this control is disabled OUT The Output Signal Again there is the level meter and the gain control that we have already seen at the input The Mix Slider controls the dry wet balance of the output signal The value is the percentage of the wet portion When using the IQ Reverb as an insert plugin you can mix a portion of the input dry signal to the reverberated wet signal The lock blocks resetting this value when loading a new IR or an IQ Reverb Preset TIME The Reverb Time T 35996 Damp The time how long a reverb lasts is called the Mo ORT6O 2 645 Stretch reverb time It is defined as the time that it takes E Reset ag until t

8. ause of that HOFA IQ Reverb can do it both ways The gate is triggerd by the dry input signal and controls the wet output signal The colour around the GATE switch will change when the gate is working You can adjust the timing using the Hold and Release controls Like with any other dynamic processing you need to adjust the threshold to your input signal To make sure that you don t forget this the threshold slider will blink when you select an IQ Reverb Preset that makes use of the gate The cut time as well as the gate hold time can be adjusted either in milliseconds or as note lengths You can switch between the modes using the appropriate Beate switch The note lengths can be selected between 1 32 and 1 1 also as dotted or triplets The song tempo will then adjust the time Tempo changes are also recognized by the plugin MOD The Modulation A general cutoff with convolution reverbs is the fact that an impulse response is always a static representation of the acoustics of a room or another reverberation device Dynamic changes can not be transported But often it is the little changes that make a sound lively The modulation of HOFA IQ Reverb will produce exactly this missing warmth and liveliness that the impulse response alone does not have M Rate 3 3 Hz d D Depth 33 0 POS The Positioner To position a sound source in your mix you need to find a O perfect combination between volume panorama and delay
9. ay the reverb in relation to the direct signal which is important to achieve the impression of different distances If you think that the borders that separate the three parts of the IR are not chosen well by IQ Reverb you can further adjust them manually using the two Border sliders In order to see better what you are doing here the spectrum view is automatically zoomed to the beginning of the IR when moving the Predelay or Border sliders You can switch this off under Settings gt Auto zoom if you want TEST Listen To Your Changes Instantly Seel Even though the 3D IR spetrum view can tell you a lot about ae eee the reverb that is currently used you will always want to vol Op know what it souds like When the Auto button is activated any modification of parameters will trigger the testsound selected above Using the Play Stop button you can also control it manually When the loop button in the middle is activated the test sound will be played in an endless loop until you stop it Below there is a volume control Please note Some DAWS like e g Logic will switch off the processing of all plugins if playback is stopped and there is no input signal This causes two problems First the reverb that IQ Reverb produces will be stopped when playback is stopped and second the testsounds also will not work anymore Normally it will help if you switch on the input monitoring so that the plugins keep running FREQ Frequency De

12. he reverb of a signal has decreased by 60 dB For this reason the reverb time is often abbreviated as RT60 reverb time 60 dB The length of an impulse response itself can be different This depends on how long the measurement was done when creating it or to what length it has been cut afterwards Because of that you will find two time displays here At the top you can see the length of the IR and below is the RT60 that has been calculated for it HOFA IQ Reverb allows modifying the reverb time of an impulse response to make it always fit perfectly to you your mix To do this there are generally two options Damping and stretching With the controls Damp and Stretch you can make use of these two options of modifying the reverb time independently The percent values are always related to the RT60 that was calculated for the unmodified IR To increase the reverb time the decreasing of the impulse response to the end has to be more slowly The spectrum view over time has to become more flat When using the Damp slider to increase the reverb time the volume of the IR is increased towards the end The whole thing is more or less tilted up When increasing the Stretch value the IR is stretched like a rubber band which will also make the spectrum view more flat Shortening the reverb time works the Same way but in the other direction An empty tile room has a longer reverb time than a room with furniture and carpets because sound waves
