When importing audio into Captivate, you have two options: WAV and MP3. Assuming you haven't studied up on the meaning of WAV and MP3, allow me to fill you in.
The WAV format was developed jointly by Microsoft and IBM as the standard format for sound on PCs. WAV sound files end with a .wav extension and can be played by nearly any computer that supports sound. Since WAV files are not compressed, they can get huge.
MP3 (MPEG Layer 3) is a compressed audio format that allows for high quality sound that is significantly smaller than its WAV cousin.
Captivate converts imported WAV files into MP3's when you publish.
Okay, so now that you know the difference between a WAV and an MP3, let's move to the import process. You can import audio into a Captivate project in any one of three places: any slide object (show the Properties on an object, select the Audio tab and click Import); the slide (show the Properties of the slide, select the Audio tab and click Import); or the project (choose Project > Background Audio and click Import).
The decision to import an MP3 as opposed to a WAV really depends on what format you recorded or were provided. If you have an MP3, you will be happy to hear that MP3's generally import into Captivate without a problem. However, WAVs can get a bit testy (I said that MP3's generally import fine, but they have been known to cause problems too.).
It may surprise you to learn that WAV's are not created equal. In fact, most audio editing applications offer several WAV export formats including, but not limited to: PCM RAW, Windows PCM, DVI / IMA wav, Microsoft AD PCM and ACM Waveform. Which format will work best with Captivate? Will they all work?
The answer is that not all WAV formats will import into Captivate. How will you know if a WAV will not import? Here's how: You'll step through the import process in Captivate, find the audio file you'd like to import and you'll attempt to open it. Then you'll see this message:
Panic? You? Nahhh! You'll click OK to the message above and you'll try to import the file again (it may sound silly to try again, but I would).
Of course, you'll see the screen below after your second attempt, and your third:
At this point, you're probably starting to get that feeling of panic. Never fear. Follow these steps for one solution to the problem:
- Start Sound Recorder (On my system, the program was found at the following location: Programs > Accessories > Entertainment > Sound Recorder)
- Open the troublesome WAV file.
- Choose File > Save As.
- Click the Advanced button.
- Click the Change button.
If the problem file was a WAV, you can select MPEG Layer-3 to convert the WAV into an MP3. You can also select PCM as a format and lower the Attributes until you find one that Captivate will allow you to import.
- After selecting a Format and Attributes, click OK.
The audio file should now import into Captivate. Of course, using Sound Recorder to convert your audio files is a last-ditch process and one you should take only if you are working on your project at the mid-night hour and don't have access to an audio resource. Most audio applications allow you to batch-convert audio files, taking the chore out of converting several files.
