SPX is a file extension for audio files, created and designed to compress voice at bitrates from 2 to 44 kbps. It is mainly used for Speex audio format. This file type has many features, including acoustic echo canceling to limit echoing of audio, noise suppression to filter out background sound, voice activity detection, and more. The main draw of the SPX file extension is the wide range of bitrates at which you can compress your audio files. SPX offers narrowband, wideband, and ultra-wideband compression at 8 kHz, 16 kHz, and 32 kHz respectively. Many media players can open SPX files, which makes them easy to open and to share. Any VLC player is able to handle this file format.
