The multimedia universe has dozens file type for video and audio. PowerPoint 2010 can import the most common sound formats. Let's take a look at the types of sound files PowerPoint understands and explore some of your considerations when using them. First, let us take a moment to explain two terms, file format and codec. A file format is file type that an audio editing program exports. You can tell the file format by the extension. A codec is the program use to encode, compress, or decompress the digital data.

Working with audio file formats

The multimedia universe has dozens file type for video and audio. PowerPoint 2010 can import the most common sound formats. Let's take a look at the types of sound files PowerPoint understands and explore some of your considerations when using them. First, let us take a moment to explain two terms, file format and codec. A file format is file type that an audio editing program exports. You can tell the file format by the extension. A codec is the program use to encode, compress, or decompress the digital data.

PowerPoint will allow you to insert sound clips in the most common audio formats. WAV stands for waveform, a Windows audio file. This audio file format stores real life sounds as waveforms which means that one minute of sound can potentially result in quite a large file size. PowerPoint's built-in sound clips are in wave format. A Windows media audio file or WMA is the default file format you will come across on your PC. It is recognize by all Windows applications because it is a native Microsoft format.

This file format compresses audio using the Windows Audio Video codec developed by Microsoft to distribute recorded music. An AIFF audio file, which stands for Audio Interchange File Format, are waveform files stored in a 8-bit mono or one channel format which is not compress and can also result in large files. An MPS audio file is a sound file that has been compress using MPEG audio layer 3 codec. This the file format commonly use for digital music online and song downloads while the file sizes significantly smaller than other waveform file formats, this still runs approximately 1 MB per minute of music.

The Advanced Audio Coding or the AAC format is used on iPods and Zoom player along with MP3s. PowerPoint 2010 will support this file format as long as you have the correct codec installed. Apple QuickTime Player and FFDShow both support AAC files. An AU audio file or Unix Audio file is typically used to create sound files for Unix computers or the Web. PowerPoint also accepts MIDI files, Music Instruments Digital Interface. This is a standard format for synthesizers in recording musical instruments on computers.

Because this involves digital music and not recording sound through a microphone, the file sizes are significantly smaller. And if you have audio in a different format than the ones I have listed, you can use several third-party programs to convert your sound files to the above file formats. Microsoft Windows Media encoder or the new Expression encoder is designed to integrate with Microsoft Office and other Microsoft products, find it at microsoft.com. PFCMEDIA is a PowerPoint add-in that automates the formatting of multimedia.

For more information visit www.playsforcertain.com. VLC from videolan.org will convert almost any audio file to the one that works in PowerPoint. PowerPoint has evolved to include the most common audio formats. If your audio file is in a different format, all you have to do is convert your sound clip to one of the more common file types and and your audio will work seamlessly.
