Chapter 8 - Using the Courier file system
Courier User Handbook 8-11
8.5. Audio file formats
This section contains a little information on the audio file formats recorded by
Courier. The Courier was designed primarily as a Broadcast Wave Format (bwf)
recorder - the Broadcast Wave Format is a standard for interchanging both
compressed and linear files which was ratified by the European Broadcasting
Union (EBU) in 1997. It is based on the Microsoft WAVE audio file format which
is a type of file specified in the Microsoft ‘Resource Interchange File format’,
RIFF.
For further information on the exact bwf specification, please refer to the EBU
document Tech 3285-E “Specification of the Broadcast Wave Format” and Tech
3285-E Supplement 1 “MPEG Audio”.
The bwf file format is being adopted as the standard for professional audio
interchange by more and more commercial systems. Any system which uses the
Digigram audio playback cards is capable of using their bwf drivers to record and
play bwf files.
If you have a system which uses mpeg compressed, or linear audio, firstly contact
the distributor of the system to see if it will support bwf files. Secondly, contact
Sonifex to see if the specific file format can be written directly on the Courier.
Systems that are supported currently are Dave2000 and the ENCO DAD.
Alternatively, you can record in raw mpeg (.mp2) format, which is suitable for
many mpeg based broadcasting systems, in linear .aif file, or as a Microsoft linear
.wav file.
The Microsoft .wav file is by far the most widely used recording format currently
available, since it is the standard recording format of the Windows operating
system. There are many editing systems, such as SADiE, Sound Forge, Cool Edit,
Fast Eddie, and Gold Wave, which can handle linear .wav files and which should
be able to transfer files with Courier.
If you have any compatibility problems, or points to note for other users, please
send them to the email address at the front of this handbook.
Note : Any linear bwf files should be able to play on a linear .wav editor.
