You can run WaveLab Cast together with other applications, granting the currently active application access to the audio card.

Latency is the delay between when audio is sent from the application and when you actually hear it. While a very low latency can be crucial in a real-time DAW application such as Steinberg Nuendo or Cubase, this is not as relevant for WaveLab Cast.

The ASIO-Guard allows you to pre-process all channels as well as VST plug-ins, which prevents dropouts and allows you to process more tracks or plug-ins.

To be able to play back and record audio in WaveLab Cast, you must specify how to connect the internal input and output channels in WaveLab Cast to your sound card and indicate the device to be used for audio playback and recording.

The common editing operations apply to any Steinberg product.

WaveLab Cast adheres to the basic conventions for the Windows/macOS interface, which means that standard Windows/macOS procedures apply.

Almost all types of editing and processing that you perform in WaveLab Cast take effect on an audio selection. There are numerous ways to make an audio selection.

In various areas of the application, you can edit numerical values by using a combination of text fields and dials.

In various places in WaveLab Cast, you can change parameters and the respective values via slider controls.

You can rename items in tables in the Markers window and in the Clips window.

A peak file (extension .gpk) is automatically created by WaveLab Cast each time an audio file is modified or opened in WaveLab Cast for the first time. The peak file contains information about the waveform and determines how it is drawn in the Audio Editor or in the Audio Montage window.

WaveLab Cast can load audio samples in many formats. Internally, it processes them as 64-bit float samples.

The EBU loudness recommendation R-128 establishes well-defined methods to measure loudness, dynamics, and peak values, and also defines reference values to achieve for these measurements. Though the reference values are intended for the broadcast world, the measurement methods are helpful in any application dealing with audio and loudness control.

In WaveLab Cast, you can set some dialogs and warning messages to Do not show again. To show these dialogs and messages again, you must reset the default answers.

The Audio Editor provides tools and functions for sample-accurate audio editing.

In the Audio Montage window, you can assemble audio clips to create a montage. You can arrange, edit, and play back clips on stereo or mono tracks.

WaveLab Cast offers various tool windows that allow you to view, analyze, and edit your audio.

Tool windows and meter windows can be used as docked windows, as floating windows, or as slide-out windows. You can freely drag around the windows and dock them to various locations.

Slide-out windows are hidden in the frame of the Workspace window. When you hover the mouse pointer over the window name, the window slides out. It is hidden again when you click anywhere else.

The File tab is the control center of WaveLab Cast.

The Info dialog provides information about the active file and allows you to edit the audio properties of audio files and audio montages.

The command bar at the top of the editor windows allows you to create, open, and save files, and to undo/redo changes.

The status bar at the bottom of the Audio Editor and the Audio Montage window shows information about the active window using the units specified for the rulers.

WaveLab Cast offers various context menus, which contain commands and/or options pertaining to the active window.

WaveLab offers you a wide range of options and tools for zooming in the Audio Editor and in the Audio Montage window.

You can create presets to save your preferred settings.

You can copy information about the name and location of the selected audio file, including any selection information and the cursor position. This information can be pasted into an external text application.

When you are editing inside a floating window or a tool window and you want to switch the focus back to the Audio Editor or the Audio Montage window, you can use the Set Focus on Current File option.

The Transport Bar allows you to control the playback of an audio file or an audio montage, to navigate to various positions in your audio, and to open the Recording dialog.

You can use the time ruler to jump to a position and start playback from there.

During playback, you can alternate between playing back the left/right, mid/side, channel clusters of multichannel audio files, or both audio channels.

Playback scrubbing helps you to find a specific position in an audio file by restarting playback repeatedly while you click and drag on the time ruler during playback or using the Play tool.

Controlling playback in the Audio Montage window basically works just like in the Audio Editor, aside from a few features that are exclusively available for audio montages.

The Audio Editor window displays audio files graphically. It allows you to view, play back, and edit individual audio files.

The channel control area to the left of the waveform in the Audio Editor allows you to select channels.

Some positions, such as markers or selection edges, are magnetic. Dragged elements can snap to these positions. This makes it easier to position items accurately.

The Edit tab gives you access to tools for editing your audio files.

Before you start editing files in the Audio Editor, we recommend that you familiarize yourself with some basic file handling procedures, as editing in the Audio Editor is not non-destructive, unlike editing clips in the Audio Montage window, which leaves the source files untouched.

You can render regions of an audio files or whole audio files to a single audio file.

You can change the sample rate and the bit depth of audio files.

Metadata consists of attributes that describe the audio contents; for example, the titles of an album, the author, or the recording date of a title. The availability of the data varies, depending on the file format of the selected audio file.

The Silence Generator dialog allows you to add silence to an audio file.

You can replace a part of an audio file with a beep sound, to cover up a swear word, for example.

The Pen tool allows you to redraw the waveform in the Waveform view, which enables you to quickly repair waveform errors.

In the Audio Editor, you can perform an advanced analysis of your audio to identify areas with specific properties. This helps you to find problem areas such as glitches or clipped samples. You can also check general information, such as the pitch of a sound.

Using the 3D Frequency Analysis, you can view an audio file in the frequency domain.

In the Gain dialog, you can define a specific gain value to change the level of an audio range, and you can choose from two types of crossfades to ensure a seamless transition from the selection to the surrounding audio material.

In this dialog, you can change the peak level of an audio file.

You can use the Loudness Normalizer to achieve a specific loudness.

A fade in is a gradual increase in level and a fade out is a gradual decrease in level.

A crossfade is a gradual fade between two sounds, where one is faded in and the other one is faded out, to ensure a smooth transition.

WaveLab generates a designated folder for each audio montage that you create. The essential file of an audio montage, the one with the .mon extension, is automatically saved in this folder, which can contain further files or sub-folders related to the audio montage.

The Audio Montage window is where you assemble, view, play back, and edit audio montages.

The tabs in the Audio Montage window give you access to the tools and options you need for editing audio montages. For example, you can edit fades in clips, adjust the settings for zooming, and render the audio montage.

The audio signal follows a specific path when passing through the various areas of WaveLab Cast.

To create an audio montage, you can either take a top-down approach and start with the general setup or a bottom-up approach; that is, use individual files as the basis.

You can duplicate audio montages in various ways. This allows you to quickly create new audio montages using the same properties and audio files as for previously created audio montages.

In the Audio Montage Properties, you can define the sample rate of the audio montage.

An audio montage consists of references to one or multiple audio files. These references can be broken if you move audio files to another location on your hard disk, for example. WaveLab Cast detects broken references and allows you to specify new file locations or replace the missing audio file with another audio file.

You assemble your audio montage by adding tracks and clips.

All clips are displayed in the Clips window. In this window, you can edit and rearrange clips and drag them into the audio montage.

You can edit files that are used in the active audio montage in the Audio Editor.

For clips in the audio montage, you can create envelopes for volume and fades, and for panning.

Ducking allows you to attenuate the level of an audio track so that the audio on another track is more prominent when both tracks are played back simultaneously.

A fade in is a gradual increase in level and a fade out is a gradual decrease in level. A crossfade is a gradual fade between two sounds, where one is faded in and the other faded out.

You can add VST effect plug-ins to tracks of an audio montage. Track effects affect all clips on a track.

The Render function allows you to mix down the whole audio montage or a region of it to a single audio file.

You can import audio CD files. The imported audio CD opens as an audio montage.

You can record single or multiple tracks directly in the audio montage. For example, this allows you to record each speaker of a Podcast to a specific track.

Input monitoring means listening to the input signal after it travels through the effects while preparing to record or while recording. This allows you to listen to the effects that your WaveLab Cast setup has on your input signal.

When you are recording, you can click the marker buttons to add markers to the recorded file.

In this window, you can apply effect plug-ins, adjust the master level, and render the audio file or audio montage.

By default, the Master Section is active. You can bypass it for each file individually or globally.

By rendering the effects using the Render function in the Master Section, they become a permanent part of a file. So instead of performing all processing in real time during playback, you can save the audio output to a file on disk.

You can save any settings that you apply in the Master Section as a preset, which can be loaded again at a later point in time.

When rendering, you can monitor the process, and you can pause or cancel tasks.

A dropout most likely occurs when your computer does not have the processing power to handle all used effect processors.

You can use different marker types to locate certain positions quickly.

In the Markers window, you can create, edit, and use markers while working on an audio file or an audio montage.

You can create markers in the wave window and montage window in stop mode or during playback. You can create specific markers if you already know what you want to mark, or create generic markers.

Markers can be deleted in the wave window or the montage window, and in the Markers window.

You can adjust marker positions in the Audio Editor or in the Audio Montage window.

For a better overview, you can hide marker types.

You can convert markers of a specific type to another type.

You can change the names of markers.

There are several ways to select markers.

You can select the audio between two adjacent markers or between any two markers. This allows you to select a section that has been marked.

In the Audio Montage window, you can bind markers to clips. By doing this, the marker remains in the same position, relative to the clip start/end, even if the clip is moved or resized in the audio montage.

If you intend to upload your audio material to YouTube or Spotify, you can divide it into chapters so that your audience can select and play particular parts of the content.

WaveLab Cast contains a variety of audio meters that you can use for monitoring and analyzing audio. Meters can be used to monitor audio during playback, rendering, and recording. Furthermore, you can use them to analyze audio sections when playback is stopped.

You can set up most meters in the corresponding settings dialogs. For example, you can adjust the behavior, scale, and color of the meters.

You can reset the display of some meters, for example, the Level Meter.

You can save any settings you applied to a meter window as a preset. By assigning presets to preset buttons, you can quickly switch between different level scales and display modes, for example.

The Level Meter displays the peak and average loudness/decibel levels of your audio file.

The Spectroscope shows a graphical representation of the frequency spectrum, analyzed into 60 separate frequency bands, represented as vertical bars.

You can loop the audio selection and tweak the loop during playback.

In this dialog, you can import one or multiple titles from an audio CD.

You can import audio from audio CDs into WaveLab Cast projects.

The video track in the audio montage allows you to add video files to your audio montage.

A video clip is created automatically when you import a video file to an audio montage.

If you import a video to your audio montage and start playback, the video plays back in the Video window. You can resize the Video window and undock it to place it on another screen, for example.

When working with video files in WaveLab Cast, you must make sure that the video file type is supported.

WaveLab Cast supports different video and film frame rates. The video frame rate must match the audio montage frame rate.

WaveLab offers a special copy-and-paste feature that allows you to transfer your audio material to other applications and to continue working on it without interrupting your workflow.

Podcast host services allow you to host and distribute Podcasts. WaveLab Cast allows you to directly upload your Podcast to various host services.

If the audio file or audio montage that you want to upload to a host service is a non-encoded audio file, you can encode the audio file. Some host services only accept encoded audio files. Encoded audio file formats are MP3, MP4, M4A, or MP2, for example.

You can upload the audio that you have created in the Audio Editor or in the Audio Montage window as a Podcast episode.

The Publish tab allows you to select the host service to which you want to upload your Podcast episode. You can select different host services and select the encoder for the audio file that you want to upload.

In WaveLab Cast, you can control many functions via shortcuts to speed up your workflow. You can edit existing shortcuts and create new shortcuts.

WaveLab Cast comes with various plug-ins. You can exclude plug-ins from opening in WaveLab Cast and add additional plug-ins.

The Touch Bar at the top of your keyboard gives you shortcuts to the WaveLab Cast functions. The Touch Bar changes automatically based on where you are in WaveLab Cast and offers a subset of the available options. You can customize the Touch Bar according to your needs.

Global Preferences are preferences that apply throughout WaveLab Cast. Before you start working with WaveLab Cast, it is recommended to edit these preferences according to your needs.

This dialog allows you to define settings for editing in the Audio Editor. However, these settings also affect other parts of WaveLab Cast. You can choose defaults for editing and playback, adjust the visual appearance of the waveform displays, and determine how WaveLab Cast works with audio and peak files.
