    Four independent delay lines

    Sigmund is far from just another delay: it consists of four discrete delay units, each with its own, independent set of parameters offering an incredible degree of sound-shaping freedom. There's an ancient saying, often attributed to Aristotle: The whole is greater than the sum of its parts. With Sigmund, this is especially true: each of the delay lines has complementary modules built-in, independent from the feedback loop:

    • Multi-mode Filter (can work either in or outside of the feedback loop)
    • Overdrive module
    • Amplitude modulator (for tremolo effects) But that's not all: Sigmund has two general-purpose Modulators which can be used to auto-modulate some of the delay lines' internal parameters. There are three different modes a Modulator can operate in:
    • LFO - Used subtly on time parameter can delicately bring a sound to life, to add gently flowing, modulated warmth reminiscent of the analog delays of yesteryear. At extreme settings, the LFO is capable of twisting the input signal utterly beyond recognition and into what you might expect transmissions from an alien civilization to sound like!
    • Envelope - In combination with built-in Transient Detector gives you a very powerful tool; when applied on amplitude allows to freely shape sound’s dynamics to control how it blends in the whole mix..
    • Peak follower - It’s a must-have for a Modulator; nothing else will do such expressive wah- wah effect, when filter cutoff is influenced by. Surely in the hands of skilled sound designer it will have many other applications beyond that.

      This all adds up to an immensely powerful architecture, the potential of which can be explored nearly endlessly and often with hardly predictable outcomes. 


    Flexible Routing

    Sigmund's four delay lines can be interconnected with each other in practically every manner possible. The plugin offers a choice of nine different routing topologies which give access to completely new dimensions of sound creation. For example, say you have your delays currently running in parallel but would like to have a cascade of serially connected delays instead: you can reconfigure them instantly by choosing your desired algorithm with just a click of the mouse. For even greater convenience when working with Sigmund, the output signals of each of the four delay lines are combined in a special, purpose-built internal mixer to ensure a seamless transition between algorithms and greatly speed workflows.

    Outstanding Quality

    The signal processing solutions we chose to implement in Sigmund have allowed us to achieve an unprecedented level of audio quality! A signal being routed sequentially through each processing block suffers no loss in fidelity from one to the next and no undesirable artifacts are introduced as is so often the case with some of the more widely used but inferior solutions. With Sigmund, each delay line is absolutely alias-free: the only sonic colorations you'll ever hear are the ones you've intentionally created.

    The signal path design process that went into Sigmund has been zero-compromise from beginning to end: in fact, the sound quality is so high, the processing so pure that it's possible to work with even the smallest delay times, even down to one-tenth of one millisecond with zero artifacts emerging. Thus, it's possible without any tricks or half-measures to use a single delay line not only as a traditional delay effect but also as a chorus or flanger and in some of the highest audio quality theoretically possible!
