Audio file compressed using Speex compression and saved in the Ogg Vorbis container format; designed as an audio compression format specifically for speech; compresses voice at 2 to 44 kbps and supports 8 kHz, 16 kHz, and 32 kHz compression in the same bitstream.
An OGG file is a compressed audio file that uses free, unpatented Ogg Vorbis audio compression. It is similar to an .MP3 file, but sounds better than an MP3 file of equal size, and may include song metadata, such as artist information and track data. OGG files are supported by many software music players and some portable music players.
