Source Editor: Audio Sources

The Source Editor for audio sources, different from the Source Editor for plug-ins, can be open from the Contents Editor: SFX, the Contents Editor: Music Track, or the Contents Editor: Voice. Just double-click the audio source icon.

[Note] SoundSeed Grain Source Tab

Wwise SoundSeed Grain, a premium plug-in that provides a granular synthesizer to Wwise users, is unlike other plug-ins in that it has a Source tab. Essentially, it is the same as the Source Editor for audio sources. However, in addition to the information provided in this page, SoundSeed Grain users should consult Source Settings for details on features, such as Markers, specific to SoundSeed Grain.

It contains information about the audio source, including the filename and duration of the audio file. An audio source is a separate abstraction layer between the audio file and the object. The audio source is created and linked to the original audio file when it is imported into your project.

For more information about the Source Editor, refer to Editing Audio Sources.

Audio Source Properties

Interface Element

Description

Name

The name of the object.

Source Plug-in

The name of the audio source WAV file.

Notes

Any additional information about the object properties.

General Settings Tab

Interface Element

Description

Click the Configure Columns... shortcut (right-click) option from the column header band.

The Configure Columns Dialog opens. Specify which columns to display and their order.

Source

Indicates if the information in the other columns, described below, refers to the Original version of the file or after it was Converted.

Channels

The number of distinct audio channels included in the audio source file.

Sample Rate

The value in Hertz (Hz) representing the number of times per second the audio source's digital audio signal is sampled.

File Size

The value and unit of measurement describing the memory size of the audio source file.

Duration

The length in seconds, from start to finish, of the audio source file.

Format

The audio format, such as PCM or ADPCM, of the audio source file.

(Link/Unlink)

Displays whether the make-up gain is applied across all platforms.

Make-Up Gain

The amount by which the volume level of the original audio file is increased or decreased.

Default value: 0
Range: -24 to +24
Units: dB

Channel Config

A list of possible channel configurations for the source, which can be selected for display in the graph view.

The audio waveform always has a Wwise display ordering. For 5.1, this corresponds to L + R + C + SL + SR + LFE, from top to bottom on the left side of the graph view. For Ambisonics 1st order, this corresponds to W + Y + Z + X.

Wwise interprets the selected channel configurations and outputs them in the graph view according to the display order. The source channel configuration can be interpreted according to any of the following file ordering varieties:

  • SMPTE: By default, Wwise interprets the file order as SMPTE (the Microsoft standard), unless it has an ambisonics header. For 5.1, it would appear as 5.1(L,R,C,LFE,SL,SR).
    However, the default is indicated in the list with Detect [channelconfig], where “channelconfig” indicates the detected configuration. For 5.1, it appears as Detect [5.1(L,R,C,LFE,SL,SR)].
  • FuMa: By default, for Ambisonics Component Ordering, Wwise interprets the file order as FuMa. For Ambisonics 1st order, it would appear as 4(Ambisonics) (FuMa).
    However, the default is indicated in the list with Detect [channelconfig], where “channelconfig” indicates the detected configuration. For Ambisonics 1st order, it appears as Detect [4(Ambisonics)(FuMa)].
  • Anonymous: The anonymous Channel Config options simply number the channels in order of appearance for the graph view. So, an Ambisonics 1st order file would appear as 4 (Anonymous); and it just displays as 1 + 2 + 3 + 4 in the graph view. Likewise, a 5.1 file would be listed as 6 (Anonymous); and it just displays as 1 + 2 + 3 + 4 + 5 + 6 in the graph view.
  • Film: Apart from ambisonic files, the alternative file orderings in the list are Film. For 5.1, it would appear as 5.1(L,C,R,SL,SR,LFE).
  • AmbiX: For ambisonics, the alternative file orderings in the list are AmbiX (ACN ordering with SN3D normalization). For Ambisonics 1st order, it would appear as 4(Ambisonics)(AmbiX).

Default value: 0

Crossfade duration

Defines the region around the loop points for which a crossfade is applied at each loop. This enables smoother loops and can be used to remove clicks and pop that can occur for certain loop points.

Default value: 0
Range: 0 to 60000
Units: ms

Override file loop points

Defines which loop points are being used:

  • Checked: The loop points from the project are used.
  • Unchecked: The loop points from the WAV file are used.

Default value: false

Mode

Defines which mode is used to display the waveform.

  • Peak: The standard display mode. Each channel is displayed. The values represent the peak PCM values in decibels for the region drawn.

  • RMS: Shows the RMS (Root Mean Square) values. All channels are collapsed. The values represent the peak RMS values for the region drawn.

Reset

Resets the following elements:

  • Trim start and end

  • Loop start and end

  • Override file loop points

  • Fade-in and fade-out

  • Crossfade duration

  • HDR envelope

  • Play Cursor

Graph View (Refer to Chapter 43, Getting to Know the Graph View for an overview.)

Waveform

Shows the contents of the PCM (WAV or AMB) file, in Peak or RMS mode, over a timeline.

For more information on channel names and configurations, refer to Understanding Channel Configurations.

Envelope Edit - HDR


Defines if the editing of the HDR envelope is enabled or not. For this option to appear, the following conditions must be present:

  • Parent object is routed to an HDR-enabled bus

  • Parent object enables the Envelope Tracking

Trim Start

Defines the trim begin position. Any content to the left of the Trim begin will be excluded during conversion and playback.

Default value: -1
Units: s

Trim End

Defines the trim end position. Any content to the right of the Trim end will be excluded during conversion and playback.

Default value: -1
Units: s

Loop Start

Defines the loop start.

[Note] Note

The loop points are only used when the parent sound has looping enabled.

Default value: -1

Loop End

Defines the loop end.

[Note] Note

The loop points are only used when the parent sound has looping enabled.

Default value: -1

Fade-in handle

Defines a fade-in region. The fade-in curve can be right-clicked to select which fade curve to apply.

Fade-out handle

Defines a fade-out region. The fade-out curve can be right-clicked to select which fade curve to apply.

(Play cursor)

The timeline differs from the waveform in regards to the manipulation of the Play Cursor's position. The timeline allows you to drag and drop the Play Cursor to wherever you wish the playback to start from. The waveform's Play Cursor cannot be dragged and dropped. However, the same result can be achieved by clicking directly on the waveform.

Customizing the starting position of a Sound SFX or Sound Voice by moving the Play Cursor to the desired starting point will only affect the playback sound in the Authoring tool. In-game, and through any indirect object (such as a parent or Event which is linked to the Sound SFX or Sound Voice on which the Play Cursor was modified), the playing of the clip will not start from the custom start point, rather it will start from the beginning.

Clicking on the Transport's Play button plays the clip from the Play Cursor's position. Clicking on the Play button while a Play Cursor continues to run will add another Play Cursor that will concurrently play from the same starting position as the first Play Cursor.

[Note] Note

The Source Editor's Play Cursor will only work on a Vorbis encoded source if the latter is converted with a seek table.

Identifies an Audio Source integrity issue.

Place the mouse over the icon to see the integrity issue on the tooltip.

Click the yellow triangle icon to attempt fixing the issue.

For more information about integrity issues, refer to Resolving Audio Source Integrity Issues.

[Caution] The alert icon may be hidden from view

If focused in to a specific region of the graph, the upper right corner of the graph - where the alert icon appears - may be hidden from view.

Conversion Tab

For a description of the Conversion tab properties, refer to Common Property Tabs: Actor-Mixer Objects.
