TAE
®
TAE
®
is ARTURIA's outstanding technology dedicated to the digital reproduction of analog circuits
used in vintage synthesizers.
When implemented in software code, TAE
®
algorithms guarantee authentic emulation of hardware
specifications. This is why the Origin hardware synthesizer and all of ARTURIA’s software
synthesizers offer an unparalleled sound quality.
TAE
®
combines four major advances in the synthesis domain:
2.3.1
Aliasing-free oscillators
Standard digital synthesizers produce aliasing in high frequencies, especially when using Pulse Width
Modulation or FM.
TAE
®
allows the production of totally aliasing-free oscillators in all contexts (PWM, FM…), without
extra processing costs.

2.3.2
A better reproduction of analog oscillator waveforms
The waveforms produced by the oscillators in analog synthesizers are marked by the presence of a
capacitor in the circuits. The discharge of the capacitor results in a light bend in the original
waveform (notably on sawtooth, triangular and square waveforms). TAE
®
allows the reproduction of
this capacitor discharge. Below is the analysis of a waveform from one of the original instruments
that ARTURIA’s software emulates, and that of the Origin. Both are equally deformed by the
distortion caused by the capacitor discharge.
