Activity 02 - Vocal Removing

Vocal Remover

Vocal Remover is an online application that helps to remove vocals from a song by creating karaoke. Once a song is chosen, its artificial intelligence will separate the vocals from the instrumental ones. We are able to get two tracks - a karaoke version of your song (no vocals) and acapella version (isolated vocals).

The songs I tried out with Vocal Remover was "Romantic Opera" by Kasun Kalhara.

Observations

At some parts of the audio clip which contains only the vocals, more variations than of the original version could be observed.

To see the correlation between the obtained audio files, first a duration where vocals are present in the original song was selected. Then different audio files were plotted against each other.

Appendix

%loading tracks

[instrumental, fs] = audioread("Instrumental.mp3");

[vocal, fs] = audioread("Vocal.mp3");

[full_song, fs] = audioread("FullSong.mp3");

%% take the resoective part

duration = 5;

start_m = 72*fs;

end_m = start_m + duration*fs;

instrumental = instrumental(start_m:end_m, 1);

vocal = vocal(start_m:end_m, 1);

full_song = full_song(start_m:end_m, 1);
