Wwise Help

Since compressed file formats, such as ADPCM, require that file lengths and region markers fall on sample boundaries, the zero-based samples are padded during the conversion process. This extra padding can cause problems when sounds are looped. To avoid these problems, Wwise prompts you to re-convert looped sounds to ensure that:

Wwise uses a pitch shift during the re-convert process to ensure that the files meet the requirements of the compression format. The loops remain sample accurate and the sample rate of the file is not changed.

You may also notice that looped XMA files sound somewhat differently on Windows and the Xbox 360. This occurs because the Xbox 360 uses the hardware to decode the file, which means it can apply short fades between loop points. On the PC, however, a separate WAV file is generated using the XMA encoder.

	Note
	Any loop markers in the audio file that are shorter than the sample boundaries are removed when converted in Wwise.
