Implementation of Vocos with the MLX framework.

Vocos: Closing the gap between time-domain and Fourier-based neural vocoders for high-quality audio synthesis

Paper [abs] [pdf]

Installation

To use Vocos in inference mode, install it using:

pip install vocos-mlx

Usage

Mel Spectrogram

from vocos_mlx import Vocos, load_audio, log_mel_spectrogram

vocos = Vocos.from_pretrained("lucasnewman/vocos-mel-24khz")

# reconstruct
audio = load_audio("audio.wav", 24_000)
reconstructed_audio = vocos(audio)

# decode from mel spec
mel_spec = log_mel_spectrogram(audio, n_mels = 100)
decoded_audio = vocos.decode(mel_spec)

Encodec

from vocos_mlx import Vocos, load_audio

vocos = Vocos.from_pretrained("lucasnewman/vocos-encodec-24khz")

# reconstruct
audio = load_audio("audio.wav", 24_000)
reconstructed_audio = vocos(audio, bandwidth_id = 3)

# decode with encodec codes
codes = vocos.feature_extractor.get_encodec_codes(audio, bandwidth_id = 3)
decoded_audio = vocos.decode_from_codes(codes, bandwidth_id = 3)
