It is pretty simple. You upload a song with a beat and a vocal. The song will placed in the queue, status will be 'queued'.
Once the AI engine is ready to process the song and separate it into an instrumental and an acapella, the status will change to 'processing'.
If an upload goes wrong because the file is corrupt, the status will change to 'failed'. Once a song is succesfully transformed into
an instrumental and an acapella, you will see the status completed. You can click on the button acapella or instrumental to get the WAV file.
