Wwise Help

Files in the Waveform audio format (WAV) and the ambisonics audio format (AMB) can be imported into Wwise. By reading the file header, Wwise can apply the appropriate channel configuration.

Wwise can import media files with multiple audio channels.

The following table lists each of the source channel configurations supported by Wwise and the default configuration used by Wwise.

	Note
	Wwise follows the Microsoft standard for channel ordering. The ordering in the file is different from the display ordering in Wwise. The table below shows the ordering in Wwise.

If you have a specific multichannel configuration that you want Wwise to preserve on import, you must define it in the WAVEFORMATEXTENSIBLE format chunk in the WAV header. If the channels defined in the channel mask of the WAVEFORMATEXTENSIBLE are not supported by Wwise, they will be changed automatically to supported values. For example, if a configuration defines a Left channel but no Right channel, the Left channel (0x01) is changed to the Center channel (0x04), and if a configuration defines Side (Surround) channels but no Rear (Back) channels, the Side channels (0x100 and 0x200) are changed to Rear channels (0x10 and 0x20).

You can combine individual mono and stereo audio files into a single multi-channel file using the Wwise Multi-Channel Creator application. This standalone utility is installed as part of the Wwise package and can be found in the same directory as the Wwise application. The Multi-Channel Creator allows you to create files with any multi-channel configuration so that they can be imported into your Wwise projects. You can also use this tool to flag specific mono files as the 0.1 component so they can be imported into Wwise as the independent LFE channel. For more information on creating multi-channel files with the Multi-Channel Creator, refer to Using the Multi-Channel Creator in the Wwise Tools section of the Help documentation.

Wwise can import media files with sample rates ranging from 300 Hz to 192 kHz.

Wwise can import media files with the following bit depths:

	Note
	Wwise can also import 32-bit float PCM files; however, the maximum conversion format is only 24 bits. Additionally, when played in the Transport Control, files are converted to 16 bits.
