2 About Wave Editor 2.1 Introduction Wave Editor is a user-friendly program for editing and recording audio files, which may be of the 'wav', 'mp3', 'vqf' or 'aiff' format. The other types of format that can also be read by Wave Editor depend on the plug-ins that have been installed. Individual audio-files can be created quickly and easily using the various filters and sound optimization methods. Wave Editor is started by: Start > Programs > ahead Nero > Nero Wave Editor.
2.2 Structure of the program Wave Editor's structure corresponds to that of the usual Windows elements: a menu bar, various toolbars and a status bar. The Wave Editor workspace shows the selected audio file. The individual elements of the window are arranged clearly and understandably, making Wave Editor very easy to use. 2.2.1 Workspace The Wave Editor workspace comprises three separate elements: the 'Sound Display', the 'Level Meter' and 'Spectrum Analyzer'.
The 'Spectrum Analyzer' displays the bandwidth of the open audio file (in decibels - dB).
3 Settings 3.1 Selecting the input and output devices To be able to record and reproduce audio files, a soundcard is needed. If a number of components that can play audio files have been installed, select the desired device. 1. In the 'Options' menu, select the 'Device Settings' command.

4 View 4.1 Specifying the view The nature of the Wave Editor display can be altered using the 'View' menu. Selecting (check mark in front of the command) of the respective command will open the corresponding Wave Editor element. Disabling this command (no check mark before the command) will ensure that the element concerned is not displayed.
4.2 How the audio files can be represented There are three different ways of displaying audio files. You can change them at any time.
4.3 Zooming With Wave Editor, audio files can be both horizontally and vertically zoomed, so that special parts of the audio files or marked elements within them can be viewed in more detail. 4.3.1 Vertical zoom The vertical zoom determines the height of the curve progression displayed and can be changed by selecting the desired zoom setting. The vertical zoom setting can only be changed if the vertical zoom bar is displayed.
4.3.2 Horizontal zoom The horizontal zoom determines the size of the audio file that is visible in the audio display. The size of the zoom determines how accurately the curve progression can be recognized. It can be set using the appropriate button on the standard menu bar (or via the 'View' menu). The following example shows a complete audio file. In the status line you can see that the file is displayed from second 0 to second 5.524. to zoom in on the section.

5.6 Editing audio files One particular feature of Wave Editor is its ability to edit audio files nondestructively. This means that changes to the audio file (e.g. as a result of using special effects or sound enhancement) can be checked immediately without having to perform a time-consuming recalculation of the audio data. The edited audio file is only computed while it is being saved. 5.6.1 Muting Muting removes all the signals in the section selected. 1.
2. In the 'Volume' menu, select the 'Change Volume' command. Push the slider in the direction required (pushing it upward will lead to a higher maximum level; pushing it down will result in a lower maximum level) then click on the 'OK' button.
