Wavesfactory Spectre v1.5.5

Spectre is a sound-shaping tool that combines the best features of an enhancer coupled with a graphical parametric equaliser.

Spectre processes the difference between the input signal and the EQ signal, introducing harmonic content to just the part of the spectrum that you want from a variety of saturation algorithms based on classic recording hardware.
Spectre can be used on individual tracks, sub-mixes, the entire mix and is ideal for mastering.

Multi-band enhancer
Spectre does not work like a conventional EQ. Spectre introduces harmonic content that was not in the original recording, bringing colour and life to the sound, not possible with a conventional EQ. This ability to offer almost phantom content across the audio spectrum led us to the name Spectre.

Spectre process the incoming audio with a five band parallel EQ, it extracts the difference between this signal and the dry input and process it through one of the ten saturation algorithms included, then it mixes it back with the dry input. The result is a signal with character, full of color, with bigger and warmer low frequencies, shiny shimmering highs and powerful mids.

It can bring dull recordings back to life, it can make a bass track more suitable for small speakers and it can even work as a high-end stereo widener thanks to the mid / side matrix.
Spectre lets you sculpt the sound of your tracks with an easy and familiar EQ workflow.
