What is an SPX File?

An SPX file is an audio file encoded with the open-source Speex Audio codec and saved in the Ogg Vorbis container format. Speex offers Voice Activity Detection (VAD), Discontinuous Transmission, Noise Suppression, Echo Cancellation, Variable Bitrate (VBR) Encoding, and Intensity Stereo Encoding (DTX) which is why it is mostly used to store voice recordings for games, podcasts, sound effects, and sometimes music. It also supports 8 kHz, 16 kHz, and 32 kHz compression in the same bitstream as well as voice compression at 2 to 44 kbps.
