FluidAudio is a Swift SDK for fully local, low-latency audio AI on Apple devices, with inference offloaded to the Apple Neural Engine (ANE), resulting in less memory and generally faster inference.
The SDK includes state-of-the-art speaker diarization, transcription, and voice activity detection via open-source models (MIT/Apache 2.0) that can be integrated with just a few lines of code. Models are optimized for background processing, ambient computing and always on workloads by running inference on the ANE, minimizing CPU usage and avoiding GPU/MPS entirely.
