Wwise Help

The Multi-Channel Creator supports a wide variety of standard channel configurations, identifying channels with suffixes, as specified in the Settings dialog (for example, "FL", "C", "LFE", and so on). It also supports anonymous configurations, where channels simply follow the order prescribed by the user. Suffixes for such configurations consist of numbers. The Multi-Channel Creator can generate anonymous multi-channel audio files of up to 255 channels.

The Multi-Channel Creator only supports files in the PCM audio format (.wav). If you try to use other file formats that are not supported, you will encounter errors while generating the output files. These errors are displayed in the generation log.

The Multi-Channel Creator also preserves the position of all markers and loop points in the original source files. If duplicate markers or loop points are found in the source files, the Multi-Channel Creator removes the duplicate and preserves only one instance of the marker or loop point in the output file.

The Multi-Channel Creator is installed in the same folder as the Wwise application when you install Wwise. The Wwise Multi-Channel Creator can be launched via the list next to the Launch Wwise button in the Audiokinetic Launcher. After you have finished creating your multi-channel files, you can exit the application.

Before using the Multi-Channel Creator, you must define the application's settings. These settings are saved per user in the application data folder (Application Data > Audiokinetic > MultiChannelCreator).

The settings include a set of suffixes that will be used to represent the different channels or set of channels that make up a multi-channel audio file. After these suffixes have been defined, you must add them to the end of each source's filename so the system can easily identify which input files contain which channels. Since your input files can either be mono or stereo files, you can define both mono and stereo suffixes.

For example, let's say you want to create a 5.1 explosion sound called 'Bang.wav' for your Wwise project. You have the six different mono sounds for each channel:

For the purposes of this example, the default suffixes will be used, but you can use any suffix you want as long as it is defined in the Settings dialog. The following table demonstrates how the suffixes can be added to the source filenames.

After the suffixes have been added to the filenames, the Multi-Channel Creator will be able to provide you with a list of possible multi-channel configurations from which you can choose the one you want.

Another option in the Settings dialog allows you to determine how the system will handle source files of different lengths. The Multi-Channel Creator can deal with these cases in two different ways, by either padding the shorter files with silence so that they are all the same length or by simply aborting the multi-channel file generation process.

Before you can generate your multi-channel files, you must prepare your source files by doing the following:

After this is done, you are ready to begin creating the multi-channel files that will be used in your Wwise project.

The creation process involves the following steps:

Anonymous channel configurations are configurations where channel roles are not known beforehand, such as "Front Left" or "LFE". They simply follow the order prescribed by the user. Special plugins have to be used in order to interpret them at run-time. Anonymous multi-channel files may consist of up to 255 channels.

Two steps are required in order to create an anonymous multi-channel file:

Mono files will be sorted according to the value of their suffix, and will be taken together into an anonymous multi-channel audio file.

For example, let's say you want to create a 4 channel anonymous multi-channel audio file from 4 mono files. Open the Settings dialog and type, say, "." as the Suffix Separator for Anonymous Audio Files. Then, you may give them the following names:

An anonymous configuration identified as "4 (Anonymous)" will be available in the main screen. Upon generation, an anonymous multi-channel file will be created. Channels will be ordered in ascending order of suffixes, as listed above.
