AtomicTransient is an innovative plugin for polyphonic audio-material manipulation and multichannel/polyphonic transient- and envelope shaping.

AtomicTransient allows appropriate "note-based"/sound-event envelope processing in polyphonic audio material. Ideal for mixes, loops, recordings. Refined algorithms provide precise and clear transient recognition and excellent dynamic adjustments.


It handles up to three channels where each channel processes all parameters separately. Use the channels e.g. for guitar, bass-drum and snare-drum and adjust the detection to listen only to desired instruments.

The included effects enable universal, time-based change of the envelope or adjustments by LFO filter - in combination with polyphonic mode also for specific drums or note-based for polyphonic recording sequences like piano or guitar.


Polyphonic processing accesses the relevant parts of the sound - all other, already audible sounds remain unaffected.

This allows, for example, to respond only to the bass-instrument, the snare-drum or the hi-hat to remove or separate them, add sustain or modify the attack.

Also the envelope of bended time-overlapping sounds of polyphonic instruments become adjustable like separate 'notes'.

Multichannel / Mixing

All three channel detections are distributable over frequency ranges to separate processing of drums or instruments.

The effect-outputs can also be mixed to optional variable frequency ranges - parameters are used to modify the ratio between effect and source signal.


The integrated effects support a variety of adjustments to your audio material:

They allow to change the envelope using the ADSR effect not only dynamic in attack and sustain, it can even be overwritten with a defined ADSR line. This creates perfect fitting of Percussions by changing attack, decay, sustain and release like a "reinterpretation" of instruments by completely changing the envelope according to conception.

The filter effect modifies frequency ranges dynamically via time depending LFOs. Using resonance setting can push the sound to a typical pithy character.

Interactive live displays

A detail-context styled spectral meter displays transient events, channels and the signal itself.

To set the envelope optimal to desired values, the ADSR effect extracts a visual representation from the real envelope of the current signal.

And even more...

Two "listen" functions supports the setting of parameters. AtomicTransient also supports common parameters like dry/wet, gain, auto-gain and features A/B program comparison, preset copy & paste (via clipboard as XML), integrated MIDI learn,
a scalable/resizable user-interface with two different skins and almost 100 factory presets.
