MP3 is an audio coding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage and a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.
SPX (Speex) is a lossy compressed audio file format that can be used in IP telephony and podcasts. It was developed by Xiph.Org in 2003. The SPX format is considered obsolete, its successor is considered to be the more modern OPUS.
