history
Project history and usage
Speex is Xiph.Org's free, patent-free speech codec and accompanying command-line encoder and decoder. Although the codec has been superseded by Opus, it remains important in package collections because old voice software, audio files, and speech-processing stacks still need a maintained codec library and conversion tools.
Project history
The official Speex site describes the project as an Open Source/Free Software audio compression format designed for speech, intended to lower the barrier for voice applications by offering a free alternative to proprietary speech codecs. The manual credits Jean-Marc Valin and Xiph.org Foundation and covers the 2002-2007 Speex codec documentation period.
Adoption history
Speex was distributed as source through the Xiph ecosystem and packaged broadly across Unix-like systems. The official downloads page says development versions are available through Git and identifies Speex 1.2.1 and SpeexDSP 1.2.1 as the current stable releases; the input package facts show it in Homebrew, Debian, Fedora, Arch, Alpine, MacPorts, Nix, Ubuntu, and openSUSE-style package sets.
How it is used
CLI users mostly encounter Speex through speexenc and speexdec for encoding and decoding speech audio, while developers link the codec library. The official site highlights speech-specific features such as narrowband, wideband, and ultra-wideband modes, VBR, VAD, DTX, packet-loss concealment, echo cancellation, and noise suppression.
Why package nerds care
Speex is a package-manager preservation case: no longer the recommended modern codec, but still part of the free audio stack and still needed for compatibility. Packagers care about the split between the deprecated codec and the still-useful SpeexDSP code, the Xiph GitLab migration, and keeping old voice applications buildable while steering new software toward Opus.

- 2013: XiphWiki says the codec part has been deprecated since 2013.
- 2016: Speex 1.2.0 tag created in the official GitLab repository.
- 2022: Speex 1.2.1 and SpeexDSP 1.2.1 identified by the official downloads page as current stable releases.
