What is an .SPX file?

SPX files are audio files saved in the Ogg Vorbis container format and compressed with lossy Speex compression, meaning that some audio quality is lost when compressed. While SPX files may store various audio content, they most often contain vocal recordings of podcasts and video games.

The Xiph.Org Foundation replaced the Speex format with the Opus codec in 2012. While SPX files are no longer commonly used, you may still encounter the files when downloading audio recordings from the Internet or receiving recordings from a coworker or friend. You can use File Viewer Plus to play your SPX files and convert the audio to the MPEG-4 (M4A) format and various bitrates and frequencies.
