It requires specifically designed optimizations that do not apply to Intel processors. - Avoid mlx-audio when the dependency on ffmpeg for audio format handling becomes a limitation due to licensing, compatibility with existing pipelines, or specific codec requirements. - Do not opt for mlx-audio if your application does not require seamless integration within the MLX framework and does not gain any significant benefit from its specialized support. ## Common questions ### What is the difference between argmax-oss-swift and mlx-audio? argmax-oss-swift: On-device Speech AI for Apple Silicon. mlx-audio: A text-to-speech (TTS), speech-to-text (STT) and speech-to-speech (STS) library on Apple's MLX framework..
