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 218).

2.Click Browse and select the M4A, OGG, or WAV file you want at the bottom of the Resource Browser window that appears. Select Insert Audio. The Resource Browser window closes.

If the file is not available in the Resource Browser window, as in Figure 219, you can either drag and drop it from your computer into the box with the dashed line, or you can select Choose and then select the file from your computer. When the file previews, select Upload. The file then appears at the bottom of the window and you can proceed to select and insert it.
You can switch between viewing thumbnails and viewing a list by selecting the list button and thumbnail button at the top-left corner.
Search file names by typing in the Search text box.
Sort in thumbnail view using the Sorting options at the top of the Resource Browser window. Sort in list view by selecting the column headers.

3.In the Media Upload: Audio window, select 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, add a caption file for the audio in WebVTT (.vtt) format by selecting Browse, selecting the file you want in the Resource Browser window that appears, then selecting Insert Track. This Resource Browser window has all the same controls as the one you used in step 2. When the student plays the audio, the captions will float near the bottom of the screen.

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.
