The file extension SF marks audio files in IRCAM sound format. It is a format developed by the French 'Institut de Recherche et Coordination Acoustique / Musique' for the storage of audio data, which is mainly used for CSound samples and MTU systems (digital audio workstation).
In addition, with BICSF (Berkeley / IRCAM / CARL) or EBICSF there is an extended format variant with a modified header, which was used on various workstation systems from VAX, Sun or MIPS. In addition to the channel number and the sample rate, an ID for the respective workstation is specified in the header of a SF file.
SF files from different workstations are thus for the most part incompatible with each other, but can be read by IRCAM supporting programs on Windows or Mac today.
Partly, SF files can also be easily loaded via the raw import of audio software.
Most often resolving problems with opening SF files is very simple. Just install an appropriate program that supports such files. All of the listed programs support SF files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of SF files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate SF files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the Minecraft applications is not on the list, select "Browse" option in order to manually locate the directory where Minecraft has been installed.
Sometimes problems with opening SF files may not lie with the application itself, but can arise due to other causes, such as:
