Implementation of Vocos with the MLX framework in Swift. Vocos allows for high quality reconstruction of audio from Mel spectrograms.
The Vocos Swift package can be built and run from Xcode or SwiftPM.
A pretrained model is available on Huggingface.
import Vocos
// Load audio as an MLXArray
let audio = try AudioUtilities.loadAudioFile(url: ...)
// Reconstruct the audio from a Mel spectrogram
let vocos = try await Vocos.fromPretrained(repoId: "lucasnewman/vocos-mel-24khz-mlx")
let reconstructedAudio = vocos(audio)
// Save the reconstructed audio to a file.
