FAC Transient as is suggested by the name is an outstanding dynamics processor providing precise design and control of the attack and sustain stages of your instruments. Transient designers or shapers are often associated with drum enhancements and only the best of them are versatile enough to suit most of the scenarios. Of course, you know that FAC takes pride in ensuring versatility in its product line, providing subtle to drastic changes. FAC Transient is no exception to the rule! To meet this objective and to be ready for all the situations: drums, guitars, bass, vocal and much more. FAC Transient includes, in addition to the classic amplification or attenuation of the attack and sustain portion of your instrument, a fine control of the detection circuit involved in the processing. Without going into technical details, there are three envelopes built from their respective detection circuits. The first one is the contour of the input signal, this includes similar processing available in Maxima and brings you control of the treshold, time and detector algorithm. The second and third one define the contour of the attack and sustain portions and brings you a total control of the depth and duration of each stage. FAC Transient gives you all you need to design the shape of your instruments and provides them the place they deserve in your mix.

WOOTT is an Audio Unit plugin (AUv3 audio effect) inspired by the infamous OTT sound. WOOTT uses a triple band dynamics algorithm with simultaneous downwards AND upwards compression, and adds a dedicated limiter to each band. So what's all that techno mumbojumbo good for? 1. First, it slams all the loud, dominant aspects of your sound 2. Next it blows up all the subtle quiet bits that were hiding below As a result, it's perfect for: - Blowing up average sounds to massive proportions - Giving an aggressive sharp edge to synthesizer filters - Bringing out subtle details and movement that would otherwise get lost in the mix (in a hamfisted way, though) - Dusting off old breakbeat samples and loops - Hyping specific aspects of your synth lines - Making generally boring things more interesting WOOTT features: - AUv3 audio unit effect plugin - Universal (all iPads and iPhones supported + MacOS M & Intel) - Runs in all your favorite AUv3 plugin hosts: Cubasis, AUM, Beatmaker 3, Nanostudio 2, Garageband, etc. - Multi-output (requires compatible host) for post-processing the individual bands - Low-resource, so stack as many of them as you like - "[WO]OTT all the things!" - Downwards *and* upwards compressors (a rare feature on conventional dynamics plugins) - Smart soft limiter per band, adapts to its own band's specific settings - Mono switch makes low-band signal monaural for an extra tight bass Note: this is not a subtle effect. If subtle and minimal are what you're after, this is not the droid you're looking for :-)
