What is a .SPX file?

spx file icon

SPX files are audio files saved in the Ogg Vorbis container format and compressed using Speex compression. The Speex format is lossy, meaning that some audio quality is lost when compressed. SPX files may be used for saving various audio content, but are most commonly used to store vocal recordings for podcasts and video games.

The Speex format was replaced by the Opus codec by the Xiph.Org Foundation 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.
