| al@19741 | 1 The Speex is a patent-free, Open Source/Free Software voice codec. Unlike other |
| al@19741 | 2 codecs like MP3 and Ogg Vorbis, Speex is designed to compress voice at bitrates |
| al@19741 | 3 in the 2-45 kbps range. Possible applications include VoIP, internet audio |
| al@19741 | 4 streaming, archiving of speech data (e.g. voice mail), and audio books. In some |
| al@19741 | 5 sense, it is meant to be complementary to the Ogg Vorbis codec. |
| al@19741 | 6 |
| al@19741 | 7 To use the Speex command line tools: |
| al@19741 | 8 |
| al@19741 | 9 ``` |
| al@19741 | 10 % speexenc [options] input_file.wav compressed_file.spx |
| al@19741 | 11 |
| al@19741 | 12 % speexdec [options] compressed_file.spx output_file.wav |
| al@19741 | 13 ``` |
| al@19741 | 14 |
| al@19741 | 15 The Speex codec has been obsoleted by [Opus](http://opus-codec.org/). It will |
| al@19741 | 16 continue to be available, but since Opus is better than Speex in all aspects, |
| al@19741 | 17 users are encouraged to switch. |
