4.11 Spectrum editor 81

You can resize a region by placing the mouse cursor at the edges of the region (so that

a double-arrow appears) and then clicking and dragging.

To remove a region that you have drawn, click anywhere else on the waveform and it

disappears.

If you have deﬁned a region as a Source or Target, it can be selected at any time to

create a new selection using the same dimensions.

Spectrum editor functions

The Spectrum Editor has the following parts:

Selection - use this part to reﬁne and deﬁne your selection(s). You can expand se-

lections, shift selections around and deﬁne a source and target region for performing

copy operations.

Operations - use this part to perform copying, ﬁltering and processing operations.

For copying operations, you require both a source and a target region to have been

deﬁned using the Selection tab. You can choose which method to copy audio between

the Source and Target regions. You can also choose to apply processing to a single

spectrum region using a variety of different modes. See Spectrum Processing Modes

for information on each mode type.

Master Section - use this part to process and route selected spectral audio regions

through the Master Section and its effects plug-ins. This allows for frequency-selective

processing. A selected region's frequency spectrum can be routed to the Master Sec-

tion where you can choose to process it separately from the non-selected frequency

spectrum. The signal is split so that one part (region spectrum or non-selected spec-

trum) is sent to the plug-ins, while the other part can be mixed with this processed

signal, after the Master Section output.

Using the Spectrum editor

You can use the Spectrum editor in two main operational modes:

Region copying and ﬁltering (Operations tab)

This is mainly intended for audio restoration applied over brief time ranges. Selections can

be copied, pasted, and ﬁltered. This type of processing is mainly used to reduce, remove

or replace unwanted sound artifacts in the audio material, and can be carried out with great

precision. This could be useful for example, to replace part of a live recording that contains

an unwanted noise (such as a mobile phone ring tone), with a copy of a similar region of the

spectrum that only contains a "clean" signal. In general, the spectral Copy/Paste combination

gives the best results, given that the source and destination regions are properly choosen.

Master Section processing (Master Section tab)

This allows you to process a speciﬁc frequency range via the Master Section. The selected

or non-selected regions of the spectrum can be processed differently. You can also employ

a number of ﬁlters (Bandpass/Low-pass/High-pass) to further reﬁne the particular range of

frequencies to be affected by any Master Section effects.

A selected spectrum region can either be:
