Keep the Love Alive¶
Preliminaries¶
!pip install git+https://github.com/ws-choi/LASAFT-Net-v2.git/ --quiet
import soundfile as sf
import lasaft
from IPython.display import display, Audio
import warnings
warnings.filterwarnings("ignore", category=DeprecationWarning)
Sample 5: Feel this breeze - (Prod. JoeSwan) - HyungWoo & Sunmin¶
1. Download the original¶
!wget https://github.com/lasaft/lasaft.github.io/raw/master/audios/kyul.wav --quiet
mixture, _ = sf.read('kyul.wav')
2. Compare the results¶
from IPython.display import Audio, display
from lasaft.pretrained import get_v2_large_709
model = get_v2_large_709()
result = model.separate_tracks(mixture, ['vocals', 'drums', 'bass', 'other'], batch_size=4)
v1_url="https://github.com/lasaft/lasaft.github.io/raw/master/audios"
track="kyul"
print('original')
display(Audio(url="{}/{}.wav".format(v1_url, track)))
for source in ["vocals", "drums", "bass", "other"]:
print('{} (v1)'.format(source))
display(Audio(url="{}/{}-{}.wav".format(v1_url, track, source)))
print('{} (v2)'.format(source))
display(Audio(result[source].T, rate=44100))
