Let us imagine a simple case: we are playing an audio clip in which sounds around 1khz are 9 dB. For example, you can raise the signal below the threshold AND compress the signal above the threshold to "stabilize" a band. In Kirchhoff-EQ, the "Above" stage works as a compressor or upward-expander, and the "Below" stage works as an expander or upward-compressor. You can now control how dynamics react to the portion of the signal above/below threshold concurrently. Note that overall harmonic distortion is decreased whilst new even-time harmonics are generated.Ĭlick here to know more about how Harmonic Shifted Envelope Detection works. * There is no noticeable crossover between filter types while in mixed phase mode, transition is seamless.ĭynamic function of Kirchhoff-EQ. Each band could be changed smoothly between minimum and linear phase mode according to their frequency. Kirchhoff-EQ provides a mixed mode that uses zero-latency when the band frequency point is low, and uses linear phase when it is high. The zero-latency and linear phase modes have a very different sound. * No matter which phase mode currently in, if dynamic functions is turned on for a filter band, it will work on minimum-phase mode (won't affect other bands). The phase mode of Kirchhoff-EQ is switchable between zero-latency mode, analogue mode, linear phase mode and mixed phase mode, in order to meet all your phase relationship needs. Zero-Latency/Analogue/Linear/Mixed Phase Modes All vintage filter types only contain ideal linear parts of their physical model.Ĭlick here to know how circuit modeling works in Kirchhoff-EQ. This brings you more freedom and convenient operations. For a further step, unlike the original hardware that only allows to choose between several frequency positions, we modified the DSP model to make adjustable frequency points for all these types! Every type in these models can be used together with regular EQ types or other modeled types, and can be applied with dynamic functions (except lowpass and highpass types). Benefit from Robust Nyquist-Matched Transform, every EQ type precisely matches the original hardware and won't cramp near Nyquist frequency. Get vintage and modern at same time! We modeled 9 vintage EQ hardware units as a total of 32 EQ types implemented in Kirchhoff-EQ.
