Spectralizer
The Spectralizer is a type of audio “enhancer” or “exciter”. It can be put to
many uses:
To restore lost harmonics in a recording.
To improve the clarity and transparency of a recording.
To make a recording sound “warmer”.
How Spectralizer works
Most audio equipment introduces a slight low-pass filtering to the audio
signal. This means you lose “high end” or “clarity”. The lost high frequency
components often have a level close to the noise floor. This means that
simply using EQ to boost the high frequencies does not create the de-
sired effect – the noise is amplified as much as the signal.
Spectralizer can actually re-synthesize lost harmonics based on existing
lower frequencies in the material. This can create an acoustically more
pleasing result than EQ-ing.
Spectralizer basically works by generating 2nd and 3rd harmonics or
overtones.
Mid 2 Width
(0.05-5.00 Octaves)
This sets the width of the Mid 2 band, in octaves. The lower this value,
the “narrower” the bandwidth.
High Freq
(200-20000Hz)
This sets the frequency of the High band.
High Gain (+/-20dB) This sets the amount of cut/boost for the High band.
High Cut If this button is activated for the High band, it will act as a High Cut fil-
ter. The Gain parameter will be fixed.
Output (+/- 20dB) This parameter allows you to adjust the overall output level.
Left/Stereo/Right/
Mono Modes
For stereo signals you can set independent curves for the left and
right channels by clicking the corresponding button. If the Stereo
mode is activated, the curve will be applied to both channels.
When channel independent curves have been set, the left/right chan-
nel curves will be colored green and red, respectively. The currently
non-selected channel is shown with a dotted curve. If you activate
Stereo mode after independent curves have been set, the currently
active curve will be applied to both channels.
Mono mode is automatically activated for mono signals and is other-
wise unavailable.
