Common expressions
A regular expression is a formula composed of characters that have spe-
cial meanings (called “operators”). Other characters are just plain letters
and numbers that are searched for. The search engine browses the target
text one character at a time and stops as soon as it finds a sequence of
characters that matches the regular expression. Searches are not case-
sensitive.
Note that there are various versions of regular expressions. WaveLab
uses a version that represents a good compromise between power and
ease of use.
When “Regular expression” is selected for the Range, you can add regu-
lar expressions in the text field, either by typing them in manually, or by se-
lecting expressions from the corresponding pop-up menu.
The term “expression” refers to a single character, a character class, or a
sub-expression enclosed with () or {} (see table below).
The following items are available on the Regular Expression pop-up menu:
Menu item Operator Description
Any character . Symbolizes any character.
Character in range [ ] A bracketed text is treated as a single character, i.e. any
character from this text. Example: [AEW13] means A or
E or W or 1 or 3.
A hyphen within the brackets specifies a range of char-
acters. Examples:
• [F-I] means F or G or H or I.
• [A-Z0-9] matches all letters and all digits.
