Inserting Audio

Note that if you upload a WAV file, IAT automatically converts the file to M4A and OGG formats, but this is not recommended, as it reduces audio quality.

To insert an audio clip with CKEditor:

1.Click . The Media Upload: Audio window appears, displaying the Upload Audio tab (Figure 217).

2.Click Browse and select the M4A, OGG, or WAV file you want from the CKFinder window that appears.

If the file is not available in this window, click Upload and select the file from your computer. When uploading audio files in the CKFinder window, make sure the Audio folder is selected in the panel on the left.

3.Click Generate Files. IAT converts the audio file into both OGG and M4A.

4.Optional: In the Audio properties tab, you can set the audio clip to play automatically and select an alignment option (left, center, or right).

5.Optional: In the Caption Track tab, upload a caption file for the audio in WebVTT (.vtt) format by clicking Browse, then double-clicking the file you want in the CKFinder window that appears. When the student plays the audio, the captions will float near the bottom of the screen.

If the file is not available in this window, click Upload and select the file from your computer. When uploading WebVTT files in the CKFinder window, make sure the Track folder is selected in the panel on the left.

6.Click OK. The pop-up closes and the audio clip is inserted.

7.Optional: To move the audio clip, click and drag the icon at the upper-left corner.

8.Optional: To edit the audio clip, double-click it. The Media Upload: Audio window appears again.
