VocalRemover is a online vocal remover service that uses machine learning and deep learning to separate the vocal and instrumental elements from a mono or stereo source. After uploading your mono or stereo audio file, for a small fee the service processes it via their intelligence powered vocal remover. Once the process is complete you are provided with two files, the instrumental portion of your supplied file and a vocals only version. A demo is available at the VocalRemover website and you can also try it using a file of your own. I was quite impressed with the results!
