What is a SPX file?
SPX is an audio file format that contains Speex-encoded audio, designed specifically for speech. It's open-source and tailored for low-bitrate compression, making it ideal for VoIP and telephony applications.
Though less common today due to the rise of Opus, SPX is still used in certain communication systems and can be converted for playback or archival purposes.
How to open SPX files
SPX files can be played using VLC, Audacity (with FFmpeg), and other programs that support the Speex codec. They are sometimes embedded in VoIP apps or audio archives.
Convert SPX to a more common format like MP3 or WAV using AnyConv’s online converter.
