| # CHANGELOG | ||
| ## version 10.0.0 - 2020-01-07 | ||
| Better handling of cue points and regions. | ||
| ### API Changes: | ||
| - *listCuePoints()* now returns a list of objects with more information about each cue point: | ||
| ```javascript | ||
| [ | ||
| { | ||
| position: 500, // the position in milliseconds | ||
| label: 'cue marker 1', | ||
| end: 1500, // the end position in milliseconds | ||
| dwName: 1, | ||
| dwPosition: 0, | ||
| fccChunk: 'data', | ||
| dwChunkStart: 0, | ||
| dwBlockStart: 0, | ||
| dwSampleOffset: 22050, // the position as a sample offset | ||
| dwSampleLength: 3646827, // the region length as a sample count | ||
| dwPurposeID: 544106354, | ||
| dwCountry: 0, | ||
| dwLanguage: 0, | ||
| dwDialect: 0, | ||
| dwCodePage: 0, | ||
| }, | ||
| //... | ||
| ]; | ||
| ``` | ||
| - *setCuePoint()* param is now a object with the cue point data: | ||
| ```javascript | ||
| // to create a cue point the position in milliseconds | ||
| // is the only required attribute | ||
| wav.setCuePoint({position: 1500}); | ||
| // to create a cue point with a label | ||
| wav.setCuePoint({position: 1500, label: 'some label'}); | ||
| // to create a cue region with a label: | ||
| wav.setCuePoint({position: 1500, end: 2500, label: 'some label'}); | ||
| ``` | ||
| Objects that define regions can also define the following optional properties: | ||
| - dwPurposeID | ||
| - dwCountry | ||
| - dwLanguage | ||
| - dwDialect | ||
| - dwCodePage | ||
| ### New Features: | ||
| - setCuePoint() now can create both cue points and regions. | ||
| ### Fixes: | ||
| - Fix setCuePoint() bug that caused some labels to display the wrong text | ||

| You can create cue points using the **WaveFile.setCuePoint()** method. The method takes a object with the cue point data and creates a cue point in the corresponding position of the file. The only required attribute of the object is *position*, a number representing the position of the point in milliseconds: | ||
| ```javascript | ||
| wav.setCuePoint(1750, "some label for the cue point"); | ||
| // to create a cue point | ||
| wav.setCuePoint({position: 1500}); | ||
| ``` | ||
| To delete a cue point use **WaveFile.deleteCuePoint()** informing the index of the point. Points are ordered according to their position. The first point is indexed as 1. | ||
| You can also create cue points with labels by defining a *label* attribute: | ||
| ```javascript | ||
| // to create a cue point with a label | ||
| wav.setCuePoint({position: 1500, label: 'some label'}); | ||
| ``` | ||
| To delete a cue point use **WaveFile.deleteCuePoint()** informing the index of the point. Points are ordered according to their position. **The first point is indexed as 1.** | ||

| ### Create regions in files | ||
| You can create regions using the **WaveFile.setCuePoint()** method. Regions are cue points with extra data. | ||
| If you define a not null *end* attribute in the object describing the cue point, the point will be created as a region. The *end* attribute should be the end of the region, in milliseconds, counting from the start of the file, and always greater than the *position* of the point: | ||
| ```javascript | ||
| // to create a region with a label: | ||
| wav.setCuePoint({position: 1500, end: 2500, label: 'some label'}); | ||
| ``` | ||
| You can also define the following optional properties when creating a region: | ||
