Song - Instrumental = Vocals

http://photosounder.com

Disclaimer : this video was made before Photosounder had the lossless mode, and therefore it doesn't reflect at all the quality the could be obtained with a recent version of Photosounder.

Starting a song (Britney Spears' Womanizer) and its instrumental version, we open both in Photosounder, export the resulting images to Photoshop, paste the instrumental's image onto the full song's image, adjust levels so they match in brightness, then set the blending mode to Difference so that only the features present in the full song but not in the instrumental are left.

We then save the resulting image and open it with Photosounder.

Sounds like crap

[Photosounder]

@giovagb07 haha sadly it kind of does. I tried to do a better one using the lossless mode, but unfortunately I was unable to find a song and its proper instrumental.

Artifacts like hell... I wonder how it compares to Mellodyn or the Prosoniq stuff

[Photosounder]

Neither of the two do that. Also please read the video's description.

WOW!! I've always wanted to be able to isolate vocals from a song...this is really an amazing program, I think I'll check it out.

You know what you should try, Photosounder? Take those sounds of Jupiter/Saturn that are floating around on youtube and make an image from them! :D

[Photosounder]

lol actually I had a look at some of those and I was surprised to find out that some of them actually have been resynthesised from images. What I think they did was analyse the original signal and resynthesise it into something shorter using a similar technique as Photosounder does. The images themselves aren't too fascinating either ;)

@giovagb07 the artifacts are likely from two main factors: phase issues not encapsulated by the spectrogram, and the fact that "vocals" span a far larger harmonic range than the bandpass filter applied in this video. The next step would be to make a full, phase-corrected version which uses 2-D Fourier transforms with Real / Complex planes... but then they'd need to rename it to "volumesounder", which is a silly name. :p

actually its quite possible

[joejumps4fun]

Well I have a CD of my friends band back in 2001...recorded at a home studio...a bit shabby...but I want to remove the instruments to learn the lyrics and remove the vocals to learn the guitar better... I guess this is just not possible for my case :(

[New1World1Production]

yeah its really easy to get instrumental versions though just when downloading add instrumental at the end and see if you get one, if you don't its easy to remove vocals with programs like audacity.

[Photosounder]

To do it this way, yes you do. If you don't then there are other ways.
