with a virtual XY pad configured with Even/Odd Harmonics as the X-axis and ± Harmonics as the Y-axis. In multiband mode the spectrum analyzer is set as three adjustable-width bands, each controlled by its own XY pad. For each pad controls are given for mix (mix of original and excited signals) and drive (degree of excitation). Transient transformation One of Alloy’s most useful tools for mangling percussive audio content is the Transient module (Figure 2). The Transient can be configured as a single- or multiband effect. For each band both attack transient peaks and sustaining portions of the waveform can be adjusted independently. As with the Exciter, a bandwidthadjustable frequency analyzer is provided. The Transient module analyzes the incoming signal and splits each transient into attack and sustain components. Subtle to enormous changes in the character of the output signal can be achieved by adjusting time and emphasis of the attack and sustain components. The module is not limited to working with drums and percussion; it can be useful with any audio that features a fast attack transient, including piano and guitar. The Dynamic Duo Where would a decent channel strip be without a means of adjusting dynamics? Alloy’s Dynamics module gives you a full-featured Compression and Gate/ Expansion system laid out very similarly to the other Alloy modules. The Alloy module provides both a ‘Digital’ mode for precise linear compression as well as a ‘Vintage’ mode that models vintage analog equipment and their program-dependent compression and nonlinear release characteristics. A 3-band multiband mode is provided along with its accompanying frequency analyzer. Threshold as well as Ratio, Attack and Release times are controllable for both the Gate and Compressor. An Auto Gain switch provides a convenient means of making up gain, and the devices can be switched for using RMS detection. In addition, both hard- and softknee modes are available. The Alloy module contains two of these dynamics processors, which can be inserted into the processing chain serially or in parallel. These modules also have sidechaining that can trigger any of the three bands in multiband mode. iZotope reports that sidechaining is even supported in the MAS and VST3 formats for Digital Performer and Cubase/Nuendo users.
