Provides low-level audio DSP operations (resampling, noise reduction, echo cancellation) for applications that need Speex compression or speech processing. Primarily used as a build/runtime dependency for audio tools and VoIP applications rather than standalone CLI usage. Lightweight and optimized for speech applications.
