Loading Audio ❚❘❘ Note: The button is unavailable if the format of the selected file cannot support an audio track. 4. Enable Set as Audio Source, and click OK (ENTER). 5. In the Open Footage dialog, select the type of operator you want to create, and click OK (ENTER). The selected files are opened into the workspace.

For more information on opening footage, see "Creating Branches in the Workspace" in Chapter 4, "Building Workspaces''. To load audio when you import footage: 1. Select a composite. 2. Choose File | Import Footage. 3. In the file browser, select the footage that you want to import. 4. In the lower pane of the file browser, select the file that includes the audio you want to use. 5. Enable Set as Audio Source, and click OK (ENTER). The selected files are imported into the composite. In the Audio panel, the path and filename of the audio source appear, and a waveform is generated. Supported Audio File Types The three standard formats for audio are WAV, AIFF and MP3. The WAV and AIFF formats are uncompressed formats whereas MP3 is a compressed format. Combustion can work with all three types. WAV-an uncompressed audio file format created by Microsoft that has become a standard PC audio file format. Used primarily in PCs, the Wave file format has been accepted as a viable interchange medium for other computer platforms, such as Macintosh. This allows content developers to freely move audio files between platforms for processing. In addition to the uncompressed raw audio data, the Wave file format stores information about the file's number of tracks (mono or stereo), sample rate, and bit depth. AIFF (Audio Interchange File Format)-an uncompressed file format for storing digital audio (waveform) data. It supports a variety of bit resolutions, sample rates, and audio channels. The format was developed by Apple Computer and is the standard format for audio CD production. MP3 (MPEG-1, Layer 3)-a compressed file format that saves storage space at the expense of audio quality. Windows Media Player, which is included with the Windows operating system, can play MP3 files. Combustion also supports loading audio that is embedded in Video for Windows (.avi), QuickTime (.mov), and MPEG (.mpg) files. When an audio file is loaded into a Combustion workspace, the audio is copied to the workspace and cached to RAM. You can also use the QuickTime Streaming format for audio. 743

Supported Audio File Types
The three standard formats for audio are WAV, AIFF
and MP3. The WAV and AIFF formats are
uncompressed formats whereas MP3 is a
compressed format.
Combustion
can work with all
three types.
WAV—an uncompressed audio file format created
by Microsoft that has become a standard PC audio
file format. Used primarily in PCs, the Wave file
format has been accepted as a viable interchange
medium for other computer platforms, such as
Macintosh. This allows content developers to freely
move audio files between platforms for processing.
In addition to the uncompressed raw audio data, the
Wave file format stores information about the file's
number of tracks (mono or stereo), sample rate, and
bit depth.
AIFF (Audio Interchange File Format)—an
uncompressed file format for storing digital audio
(waveform) data. It supports a variety of bit
resolutions, sample rates, and audio channels. The
format was developed by Apple Computer and is the
standard format for audio CD production.
MP3 (MPEG-1, Layer 3)—a compressed file format
that saves storage space at the expense of audio
quality. Windows Media Player, which is included
with the Windows operating system, can play MP3
files.
Combustion
also supports loading audio that is
embedded in Video for Windows (
.avi
), QuickTime
(
.mov
), and MPEG (
.mpg
) files. When an audio file
is loaded into a
Combustion
workspace, the audio is
copied to the workspace and cached to RAM. You
can also use the QuickTime Streaming format for
audio.
