Edit Tab (Audio Editor)

In the Audio Editor, click Edit.

Tools

Time Selection: Allows you to select a time range.
Pen: Allows you to redraw the waveform in the Audio Editor. This helps you to quickly repair waveform errors.
Play: Allows you to play back the audio file at the position where you click.

Zoom

Zoom

Activates the Zoom tool, which allows you to define a time range that is zoomed in.

Time

Opens a pop-up menu that allows you to adjust the zoom to display the selected time range. Zoom in 1:1 zooms in so that one pixel on the screen represents one sample.

You can edit the zoom factor by clicking Edit Zoom Factor. This opens the Zoom Factor dialog, where you can choose from the following options:

Set Time Range allows you to define the time range to be displayed.
Samples per Screen Point allows you to specify the number of audio samples encompassed by each screen point.
Screen Points per Sample allows you to specify the number of screen points that represent a single audio sample.

Zoom Selection

Zooms the window so that the current selection occupies the entire window.

Microscope

Zooms in as far as possible.

View All

Zooms out as far as possible.

Display Whole Clip

Adjusts the view to display the active clip.

Zoom in Audio (10x)/Zoom out Audio (10x)

Zooms in/out in big steps.

Zoom in Audio/Zoom out Audio

Zooms in/out in small steps.

Zoom in Vertically/Zoom out Vertically

Zooms in/out to show waveforms at a lower/higher level.

Level

Adjusts the zoom to only display samples below the selected dB value.

Reset Zoom to 0 dB

Adjusts the zoom to display audio levels up to 0 dB.

Cut Copy Paste

Cut

Cuts the selected audio range to the clipboard.

Copy

Copies the active clip or the selected audio range to the clipboard.

Crossfading

With this option activated, WaveLab automatically applies crossfades when you initiate one of the following editing operations:

Cut
Paste
Crop
Mute
Delete
Prepend, Append, Overwrite, or Multiple Copies from the Paste menu

Note

To prevent WaveLab from automatically generating crossfades for particular editing tasks; for example, to perform a sharp cut or to insert audio segments that are not linked to the audio before or after it in any way, you can deactivate the option at any time.

However, apart from these special purposes, we recommend that you keep this option activated, as it avoids common editing issues, such as abrupt volume shifts or audible clicks. It ensures smooth, natural transitions between audio segments by seamlessly conjoining a fade out and a fade in.

Note

To view and edit the global settings for fading and crossfading, you can click the button in the lower right corner of the Cut Copy Paste panel.

Paste

Pastes the clipboard content.

Right-clicking Paste opens a pop-up menu that allows you to select a paste type.

Prepend inserts the audio prior to the beginning of the file.
Append inserts the audio after the end of the file.
Crossfade Over Selected End pastes the clipboard content and creates a crossfade.

Moving the mouse over Crossfade Over Selected End opens a pop-up menu that allows you to select a crossfade type for pasting:
- Linear (Equal Gain) changes the level linearly.
- Sinus (Equal Power) changes the level according to a sine curve, while the power of the mix remains constant.
- Square-Root (Equal Power) changes the level according to a square-root curve, while the power of the mix remains constant.

Overwrite replaces the audio at the cursor position.
Multiple Copies opens a dialog which allows you to enter the number of copies that you want to create.
Mix blends two files into each other, starting at the selection or, if there is no selection, at the cursor position.

If you select Mix, a dialog opens, allowing you to specify the gain and phase for the audio on the clipboard and at the destination. The clipboard data is mixed in, regardless of the length of the selection.

Crop

Deletes any data outside the selection.

Mute

Replaces the audio selection with silence.

Delete

Deletes the selection. The audio to the right of the selection is moved to the left to fill the gap.

Level

Gain: Opens the Gain dialog, where you can apply a gain to change the level of an audio file.
Level: Opens the Level Normalizer dialog, where you can change the peak level of an audio file.
Loudness: Opens the Loudness Normalizer dialog, where you can specify the loudness of a file.

Fading

Fade In/Fade Out

Allows you to apply a fade in or a fade out. Right-clicking the button opens the Curve pop-up menu.

Curve

Allows you to select preset fade curves.

Linear changes the level linearly.
Sinus (*) changes the level according to a sine curve. When used in a crossfade, the loudness (RMS) remains constant during the transition.
Square-Root (*) changes the level according to a square-root curve. When used in a crossfade, the loudness (RMS) remains constant during the transition.
Sinusoid changes the level according to a sine curve.
Logarithmic changes the level according to a logarithmic curve.
Exponential changes the level according to an exponential curve.
Exponential+ changes the level according to a more pronounced exponential curve.

Correction

Error Correction Method

Allows you to select an error correction method.

Short Resynthesis is best suited for minor errors. WaveLab Cast analyzes the immediate surroundings of the error to find the most appropriate method of correction.
Smooth Pencil Line is particularly suited for tiny clicks. This method corresponds to drawing an accurate line with a soft pencil. It replaces the corrupted sample with the pencil line.

Marker

Create Generic Marker: Allows you to create markers and marker pairs at the edit cursor position.

Generate Chapters: Allows you to generate a text file that lists the chapters in your audio material, based on the markers you set, for use on YouTube or Spotify.
Create Region Start Marker: Allows you to create a region start marker at the edit cursor position.
Create Region End Marker: Allows you to create a region end marker at the edit cursor position.
Create Generic Region from Selection: Sets a generic region marker at the left and at the right edge of the audio selection.

Signal

Silence Generator: Opens the Silence Generator dialog, which allows you to add silence or ambience sounds to an audio file.
Bleep Censor: Opens the Bleep Censor dialog, which allows you to replace a section of an audio file with a beeping sound; for example, to cover up a swear word.

Analysis

3D Frequency Analysis: Opens the 3D Frequency Analysis dialog, where you can define the frequency range to be analyzed and modify the appearance of the graph for the 3D frequency analysis.
Global Analysis: Opens the Global Analysis dialog, where you can choose from different analysis types and analyze your audio with regard to peaks, loudness, pitch, or errors, for example.

Output

Render: Starts the rendering process.

Podcast

Upload Episode: Allows you to upload your Podcast episode to a hosting service.
