Audio file editing refers to opening, editing, and saving audio files.
This section describes the principal editing operations within the Audio Editor.
You can copy sections of audio within the same file or between audio files.
Before you start working, you need to make some settings.
This chapter describes general concepts that you will use when working with WaveLab LE. Getting accustomed with these procedures allows you to work more effectively with the program.
The Workspace window provides an editing and playback environment for each particular file type. Each environment contains functions that are tailored to the specific purpose of each file type.
In WaveLab LE, you can handle files in various ways. For example, rename files from within WaveLab LE or save files in various ways.
This chapter describes the methods for controlling playback and transport functions.
The wave window in the Audio Editor displays audio files graphically. Here, you view, play back, and edit individual audio files.
The tabs in the Audio Editor give you access to the tools and options you need to edit audio files.
WaveLab LE is very flexible in its handling of stereo. All editing operations can be performed on either one channel or on both.
WaveLab LE can open and save audio files in a number of file formats.
You can create an empty audio file, to assemble material from other audio files, for example.
You can change the file format, sampling frequency, bit depth, and stereo/mono status when saving.
Audio can be saved in different formats. The process of converting audio to another format is called encoding. When saving audio files, you can specify various encoding options for some file formats.
You can assemble an audio file from several audio files.
You can turn selections into new files via drag and drop, via the context menu in the wave window, or by using the Render tab in the Audio Editor.
You can convert audio files from mono to stereo and from stereo to mono. Converting a mono file into a stereo file produces an audio file that contains the same material in both channels, for example for further processing into real stereo. Converting a stereo file into a mono file mixes the stereo channels to a mono channel.
You can swap the two channels in an audio file, that is, you can move the audio in the left channel to the right channel, and the audio in the right channel to the left channel.
On the Paste pop-up menu in the Audio Editor, you find additional paste options.
You can rearrange the order of the audio in a file by dragging, and cutting and pasting.
When you drag or copy stereo or mono files to other locations, the target location determines how the files are inserted.
If you copy or move audio from one window to another, and the sample rates of the two files are not the same, the copied/moved sound plays back at the wrong pitch (speed). The program warns you if this is about to happen.
You can render regions of an audio files or whole audio files to a single audio file.
You can change the sample rate and bit depth of audio files.
Metadata consists of attributes that describe the audio contents, for example, the title of the track, the author, or the recording date of the track. Depending on the file format of the selected audio file, this data varies.
This dialog allows you to insert silence in an audio file.
WaveLab LE provides you with a 3D Frequency Analysis for analyzing your audio.
Offline processes are useful for a variety of editing purposes and creative effects, for example, if the computer is too slow for real-time processing or if the editing requires more than one pass.
The audio montage is a multitrack non-destructive editing environment that allows you to arrange, edit, play back, and record audio clips.
You can record audio in the Audio Editor and in the Audio Montage window.
The Master Section is the final block in the signal path before the audio is sent to the audio hardware, to an audio file, or to the audio meters. This is where you adjust the master levels and add effects.
Markers allow you to save and name specific positions in a file. Markers are useful for editing and playback.
Looping a sound allows you to repeat a section of the sample indefinitely in order to create a sustain of unlimited length. Instrumental sounds in samplers rely on looping organ sounds, for example.
You can read audio tracks from regular CDs and save them as a digital copy in any audio format on your hard disk.
Podcasting is a method of distributing multimedia files over the Internet, for example, for playback on mobile devices and personal computers. Podcasts are distributed via the RSS standard (Rich Site Summary).
Customizing means making settings so that the program behaves and looks the way that you want it to.
You can configure WaveLab LE according to your needs.
