Failed to Open SPX Files?

If you have found, downloaded, or received a SPX file but don’t know how to open it, the first thing is to figure out what the file type is. A file with .spx extension is mainly associated with Speex encoded audio format, Microsoft FoxPro Compiler Screen Program, and Apple Mac System Profiler XML Report File. Are you confused by the 3 kinds of SPX types? Don’t worry, in this article, we will elaborate how to open SPX file for you.

Type 1: Speex SPX Audio File

Speex is an Open Source/Free Software patent-free audio compression format designed for speech, and the audio file is saved in the .spx extension.

However, if you still have some audio files with the .spx extension, there are a few media players that can directly open and play them, such as VLC or foobar2000. All you need to do is to launch the media player and open the SPX.

Unfortunately, as a less popular audio format, Speex audio file cannot be recognized by most software and devices, so, if you have some precious SPX files that you don't want to delete, the best way is to convert them to MP3 format.
