1 The Speex is a patent-free, Open Source/Free Software voice codec. Unlike other
2 codecs like MP3 and Ogg Vorbis, Speex is designed to compress voice at bitrates
3 in the 2-45 kbps range. Possible applications include VoIP, internet audio
4 streaming, archiving of speech data (e.g. voice mail), and audio books. In some
5 sense, it is meant to be complementary to the Ogg Vorbis codec.
7 To use the Speex command line tools:
9 ```
10 % speexenc [options] input_file.wav compressed_file.spx
12 % speexdec [options] compressed_file.spx output_file.wav
13 ```
15 The Speex codec has been obsoleted by [Opus](http://opus-codec.org/). It will
16 continue to be available, but since Opus is better than Speex in all aspects,
17 users are encouraged to switch.
