What audio file formats are supported?
SFS maintains its own file format for data. It needs this because it maintains a processing history of each data set; this allows a user to keep track of the origin and processing of any piece of data. SFS also tries to keep data sets together in a single file, to try and make the user interface simpler. This means that the SFS file format must allow multiple copies of multiple types of data in a single file; and this precludes the use of other file formats. To deal with other data file formats, SFS provides utilities for importing and exporting data. For importing signals, it is often unnecessary to make a new physical copy of the signal; instead, a command ‘slink’ simply records in an SFS file the instructions for how and where to access the data in its original format. This makes access to large read-only databases of data very convenient. SFS can link to or read speech signals in the following file formats: • binary files • WAV format (RIFF format) • VOC format • AU format • ILS fo
