Channel Configuration Override

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 1st order ambisonics, this corresponds to W + Y + Z + X.

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

SMPTE: By default, Wwise interprets the file order as SMPTE (the Microsoft standard), unless it has an ambisonics header. For 5.1, it appears as 5.1(L,R,C,LFE,SL,SR). However, the default is indicated in the list by displaying 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, Wwise interprets the channel ordering for Ambisonics Component Ordering and 1st, 2nd and 3rd order ambisonics, as FuMa. For 1st order ambisonics, it appears as 4(Ambisonics) (FuMa). However, the default is indicated in the list by displaying Detect [channelconfig], where “channelconfig” indicates the detected configuration. For 1st order ambisonics, it appears as Detect [4(Ambisonics)(FuMa)]. FuMa is not defined for higher-order ambisonics, which are only interpreted as AmbiX (ACN ordering with SN3D normalization).
Anonymous: The anonymous Channel Config options simply number the channels in order of appearance in the graph view. An 1st order ambisonics file appears as 4 (Anonymous); and is simply displayed as 1 + 2 + 3 + 4 in the graph view. Likewise, a 5.1 file is listed as 6 (Anonymous); and is simply displayed as 1 + 2 + 3 + 4 + 5 + 6 in the graph view.
Film: Apart from ambisonics files, the alternative file orderings in the list are Film. For 5.1, it appears 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 1st order ambisonics, it appears as 4(Ambisonics)(AmbiX).

Default value: 0

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

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: -0.001

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: -0.001

Units: s

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

Loop Start

Defines the loop start.

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

Default value: -0.001

Loop End

Defines the loop end.

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

Default value: -0.001

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

Crossfade Shape

The shape of the cross-fade curve. The list options are:

Logarithmic (Base 3)
Sine
Logarithmic (Base 1.41)
Inverted S-Curve
Linear
S-Curve
Exponential (Base 1.41)
Reciprocal Sine
Exponential (Base 3)

Default value: Sine

Marker Input Mode

Determines how markers are managed. You can select one of the following options:

Import From File to use markers that are saved in the original audio file.
Detect From Transients to automatically detect transients (onsets) in the audio file and add markers where they are detected. When this option is selected, the detection sensitivity slider is shown. The detection sensitivity controls the sensitivity of the onset detection algorithm.
Manual Markers to manually place markers.

	Note
	When a marker is moved or removed, or a new marker is added, the mode is automatically changed to manual.

Default value: Import From File

Marker Detection Sensitivity

The sensitivity of the transient detection algorithm. Higher sensitivity values will produce more transient markers.

Default value: 0

Range: 0 to 100

Fade-in Duration

The length of the fade-in curve.

Default value: 0

Range: 0 to 3600

Units: ms

Fade-in Curve

The shape of the fade-in curve. The list options are:

Logarithmic (Base 3)
Sine
Logarithmic (Base 1.41)
Inverted S-Curve
Linear
S-Curve
Exponential (Base 1.41)
Reciprocal Sine
Exponential (Base 3)

Default value: Sine

Fade-out Duration

The length of the fade-out curve.

Default value: 0

Range: 0 to 3600

Units: ms

Fade-out Curve

The shape of the fade-out curve. The list options are:

Logarithmic (Base 3)
Sine
Logarithmic (Base 1.41)
Inverted S-Curve
Linear
S-Curve
Exponential (Base 1.41)
Reciprocal Sine
Exponential (Base 3)

Default value: Reciprocal Sine
