2.3 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

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

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

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

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.
