Common Patterns

Audio Format

All pipelines expect 16 kHz mono Float32 samples. Use AudioConverter to normalize input:

let converter = AudioConverter()
let samples = try converter.resampleAudioFile(path: "audio.wav")

Model Registry

Override the default HuggingFace URL:

ModelRegistry.baseURL = "https://your-mirror.example.com"

Or via environment: REGISTRY_URL=...
