I/O
- Input
codes: shape(1, 1, L)Int32, flat FSQ indices 0-65535 at 50 tok/sec - Output
audio: shape(1, 1, T)Float32 at 24kHz
Swift Usage
import CoreML
let config = MLModelConfiguration()
config.computeUnits = .cpuAndGPU
let model = try MLModel(contentsOf: compiledURL, configuration: config)
let codesArray = try MLMultiArray(shape: [1, 1, 100], dataType: .int32)
for i in 0..<100 { codesArray[i] = NSNumber(value: flatCode) }
let input = try MLDictionaryFeatureProvider(dictionary: ["codes": codesArray])
let output = try await model.prediction(from: input)
// output["audio"]: shape [1, 1, T], Float32 at 24kHz
