Wangyou_Zhang_chime4_enh_train_enh_beamformer_mvdr_raw

Usage

pip install espnet
espnet enhance noisy.wav -o enhanced.wav --model espnet/Wangyou_Zhang_chime4_enh_train_enh_beamformer_mvdr_raw

import soundfile as sf
from espnet2.bin.enh_inference import SeparateSpeech

enh = SeparateSpeech.from_pretrained(model_tag="espnet/Wangyou_Zhang_chime4_enh_train_enh_beamformer_mvdr_raw")
# channels are kept on the way in: a multi-channel model needs them
speech, rate = sf.read("noisy.wav", dtype="float32")
waves = enh(speech[None, ...], fs=rate)
# one wave per output stream, which is what tells the two tasks apart: an
# enhancement model returns one, a separation model one per speaker. This is
# what `espnet enhance` writes as enhanced.wav or enhanced.spk1.wav, ...
if len(waves) == 1:
    sf.write("enhanced.wav", waves[0][0], rate)
else:
    for i, wave in enumerate(waves, start=1):
        sf.write(f"enhanced.spk{i}.wav", wave[0], rate)
