11 – 256 Spectrum Editor
Introduction
The Spectrum editor is powerful audio restoration and processing tool
set, using high quality linear-phase filters to process a spectrum selection
both in the time and in the frequency domain.
There are two main operational modes:
Surgical processing (offline processing).
This is intended for audio restoration purposes applied to short time ranges. See “Surgical
processing” on page 262.
Master Section processing.
This allows you to process a specific frequency range via the Master Section. See “Master
Section processing” on page 269.
Both modes operate according to a spectrum region, which is set using
the Spectrum selection tool. The region selection defines a time and a
specific frequency range.
This allows you to edit and process audio both in the time domain and in
a specific frequency domain, as opposed to standard wave editing which
always operates in the full frequency domain. This introduces a whole
new approach to wave editing!
Spectrum editing can perform many different types of processing, mainly
aimed at audio restoration, but could certainly also be used for artistic or
special effects – the filters are very powerful.
Basics
Selecting Spectrum display mode
Spectrum editing can only be performed when Spectrum display mode is
selected.
It should be noted that the Spectrum display isn’t really designed to be an
alternative to the Wave display when it comes to standard editing proce-
dures in WaveLab.
It is specifically meant for audio restoration purposes using the various processing methods
in the Spectrum editor, which are usually applied to very short time segments in an audio file.
