A new open-source project, audio.cpp, has launched a native C++ inference framework for audio models, leveraging the ggml library for optimized performance. The framework currently supports 12 audio model families, including text-to-speech (TTS), voice cloning, and other audio generation tasks. Benchmarks indicate TTS inference speeds up to 5x faster than equivalent Python implementations when running on CUDA. The project emphasizes native C++ execution, avoiding Python overhead, and positions itself as a lightweight alternative for developers working with audio AI models.
