About SF Files

An .sf (or .ircam) file is an audio file saved in the IRCAM Sound File format, a format developed by the Institut de Recherche et Coordination Acoustique/Musique (IRCAM) to store high-quality digital audio. SF files contain uncompressed audio data along with detailed metadata, such as sample rate, bit depth, channel configuration, and encoding type.

The IRCAM Sound File format emerged from academic and research-focused music environments, where advanced digital signal processing and sound experimentation were common. Composers, researchers, and sound designers working with computer music systems, especially in environments tied to IRCAM tools and early UNIX-based audio software. Today, SF files are most often encountered in archival research projects, experimental music collections, and legacy audio workflows maintained by specialists and audio historians.

Converting SF Files

You can convert .sf or .ircam files to other audio formats to make them easier to play and share outside of specialized audio software:

• Converting to MP3: Transforms uncompressed IRCAM Sound File audio into a widely supported format that plays on nearly all devices and media players, though the conversion uses lossy compression and reduces some of the original audio detail.
• Converting to AAC: Converts SF audio into a modern, efficient format that preserves more sound quality than MP3 at similar file sizes while remaining compatible with most current devices and streaming platforms.
