How to Open an SPX File

Updated July 20, 2017

A file with the extension .spx is an audio file that has been compressed using the program SPEEX. SPEEX compresses voice recordings at 2 to 44 kbps. While many audio players are unable play .spx files, there are free programs that will be able to play them in both Windows and Mac OS. Two of these programs are VLC Media Player and Apple QuickTime Player. Both can handle .spx files in Windows and MAC OS and can be downloaded for free online.
