Although the codec has been superseded by Opus, it remains important in package collections because old voice software, audio files, and speech-processing stacks still need a maintained codec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. ### Projektgeschichte 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. ### Adoptionsgeschichte 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. ### Wie es verwendet wird 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. ### Warum Paket-Nerds sich dafür interessieren 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. ### Zeitleiste - 2002-2007: Speex manual copyright period documented for Jean-Marc Valin and Xiph.org Foundation. - 2009: XiphWiki says the source was split into Speex Codec and Speex DSP. - 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. ### Related projects - Opus is the Xiph-recommended successor for new lossy audio and speech codec use. - SpeexDSP remains a related signal-processing library with resampling and other DSP code. ### Quellen - - - - - ## Sicherheitshinweise broad file, network, media, or database tool signal. - **Geiger-Risiko:** blue / mittel -
