Options: Here you can enter a minimum DC offset threshold, which indicates
where DC offset removal will kick in. You can also edit stereo channels
together to reduce computing time.
Spectral Cleaning
MAGIX Spectral Cleaning removes background noise (such as coughing,
whistling or clapping) from a recording without audibly influencing the signal.
The music is displayed in the Spectral Cleaning Editor by means of a
spectrogram (sometimes also referred to as a sonogram). This displays the
frequency elements with regard to time (see illustration). The frequency level is
then visualized by a color code or by its brightness, respectively.
Audible background noises are usually louder than the signal and are generally
restricted to a certain frequency spectrum. They are therefore highlighted in
the spectrogram in color and can be easily encircled and removed with the
mouse.
For example, you can recognize the held
tone from a pattern consisting of
horizontal lines that correspond with the
harmonics of the sound (see illustration
on the left). A pulsed noise is
characterized by a vertical line. The right
illustration displays a tone overlapping a
short noise.
Tone Tone with noise
In MAGIX Spectral Cleaning Editor you can now simply mark and "remove" all
noises with the mouse. Lost elements of the original frequency spectrum are
then added from the signal surrounding the noise in order to avoid audible
gaps.
MAGIX Spectral Cleaning is ideal for all short but clear sounds in the music,
such as clicking, coughing and even short drop-outs, but NOT for permanent
disturbances such as hiss or noise. In such a case please use the DeHisser or
DeNoiser.
