Although think it might still use the Cue Points... smpl chunk: "Sample Loops The sample loops field specifies the number Sample Loop definitions in the following list. This value may be set to 0 meaning that no sample loops follow. Sampler Data The sampler data value specifies the number of bytes that will follow this chunk (including the entire sample loop list). This value is greater than 0 when an application needs to save additional information. This value is reflected in this chunks data size value. List of Sample Loops A list of sample loops is simply a set of consecutive loop descriptions that follow the format described below. The sample loops do not have to be in any particular order because each sample loop associated cue point position is used to determine the play order. The sampler chunk is optional." http://www.sonicspot.com/guide/wavefiles.html#smpl |
