Analog Modelling Suite: am-pulse
(Samplitude Pro)
am-pulse is a "transient modeler", a creative tool for editing envelope and sustain
processes (attack and sustain) on percussive or dynamic signals.
In particular, the input of the signal is an important factor of acoustic perception. The so-
called transients are extremely short oscillations in the make-up of a sound which enable
the human ear to precisely differentiate sounds from one another and spatially localize
where they come from.
Alongside transient modelling this effect also allows you to enhance the signal or even
distort it. For this to work in the am-pulse, individual steps as "virtual hardware" have been
set up and designed using elements of models and components "borrowed" from the
analogue world in order to achieve smooth, organic operation with character.
Possible instances where am-pulse can be used:
• Drums (for example, kick, snare, toms, subgroup signal): Increasing or decreasing the
attack leads to a harsher or softer sound respectively, increasing or decreasing the
sustain changes the room information with overheads or ambience tracks.
• Acoustic or electric guitars and basses (accentuate or dampen the attack, e.g. for
playing with a plectrum)
• Balance volume fluctuations and explosive sounds for sound recordings
• Sinking background noises
Working method of the transient section
At first glance, it seems as if am-pulse has a dynamic compressor working “beneath the
hood”. However, this is not the case. In comparison to conventional compressors, am-
pulse is level-independent. If, for example, you reduce the attack rate of a snare drum by
6dB, this is independent of how loud it was played. However, you have to determine a
threshold as if for a compressor. No editing takes place below this threshold.
The possibilities mentioned for using am-pulse are based on the principle of “transient
recognition”.
