The available file formats
AIFC files
AIFC stands for Audio Interchange File Format Compressed, a standard defined by
Apple Inc. These files support compression ratios as high as 6:1 and contain tags in
the header. AIFC files have the extension “.aifc” and are used on most computer
platforms.
AIFC files support the same options as AIFF files.
Wave files
Wave files have the extension “.wav” and are the most common file format on the PC
platform.
Wave files support the same options as AIFF files and have one additional option:
Don’t Use Wave Extensible Format
The Wave Extensible format contains additional metadata, such as the speaker
configuration. It is an extension to the normal Wave format that some applications
may not be able to handle.
If you get problems using the Wave file in another application, activate this option
and re-export.
Wave 64 files
Wave 64 is a proprietary format developed by Sonic Foundry Inc. In terms of audio
quality, Wave 64 files are identical to standard Wave files, but in the file headers
Wave 64 files use 64-bit values for addressing where Wave files use 32-bit values.
The consequence of this is that Wave 64 files can be considerably larger than
standard Wave files. Wave 64 is therefore a good file format choice for really long
recordings (file sizes over 2
GB). Wave 64 files have the extension “.w64”.
Wave 64 files support the same options as AIFF files.
Broadcast Wave files
Broadcast Wave files are Wave files with additional meta data. To create a Broadcast
Wave file, select either Wave or Wave 64 as the file format and activate the Insert
Broadcast Wave Chunk option. Click Edit if you wish to edit the chunk information,
otherwise the defaults as specified in the Preferences dialog (Record–Audio–
Broadcast Wave page) will be used. Broadcast Wave files have the extension “.wav”.
Broadcast Wave files support the same options as Wave files.
Insert iXML Chunk This allows you to include additional project-related metadata (e. g.
project name, author and project frame rate) in the exported file.
Some applications may not be able to handle files with embedded
info – if you get problems using the file in another application,
deactivate the option and re-export.
Note: In the Project Setup dialog you will find the fields Author and
Company that you can use to include the corresponding data in the
iXML chunk. These fields are also available in the Preferences
dialog (General–Personalization page).
Insert Tempo
Definition
This option is only available if “Insert iXML Chunk” is activated.
When “Insert Tempo Definition” is activated, tempo information
from the tempo track or the Definition tab of the Sample Editor is
included in the iXML chunk of exported files. This is useful if you
want to use the files in other projects where they need to adapt to
the project tempo.
