MLX Audio

MLX Audio is an audio processing library for Apple Silicon that performs speech-to-text, text-to-speech, speech-to-speech, and music generation tasks.

MLX Audio is a library built on Apple's MLX framework for running various audio models on Apple Silicon. It supports multiple architectures including text-to-speech, speech-to-text, speech-to-speech, and music generation. Users can utilize quantization settings from 3-bit to 8-bit to optimize performance. It includes a web interface for interaction and provides an OpenAI-compatible REST API. The library targets developers working on speech applications who need efficient, local processing on macOS devices.
