QUESTION. How to Split a recording for export as separate tracks or

Seems impossible but with how algorithms are progressing Id think a software company could figure out how to do it
or software that rips the song apart into tracks like melodyne does with notes
Hope I am explaining this right lol
Anyone have any suggestions on software that does this
Free or paid
Anything useful
Thank you :)

If you're talking about separating instruments from a mixed down WAV or MP3 - no chance. That would be like separating the yellow and blue from green paint.

I think there are programs that will remove the lead vocal from a mixed song to make a karaoke track, but AFAIK that's about the limitation at the moment. Happy to be corrected if someone knows better.

I use RiffStation to remove vocals. its definitely one of the best out there.
Allows slow down and tuning changes as well.

Boy are people just getting so lazy they think you can push a button and your work is done! Computers are amazing but how on earth would that even be remotely possible! Do you understand what an audio file is? 
Do you think there's a little band in there playing live? That's just about as far fetched. 
Yes you can remove vocals, sometimes. 
 
If what your after is a backing track for playing live or making your own recordings, then you have many choices and most either involve spending money or spending time. No magic "free" button to creating backing tracks. 
 
Best shot is there are some free midi files for most popular songs but that is limited and many are not that good. 
 
Google your song title midi file. Be aware of many Phishing sites as you go. Midi files should download fast and direct without jumping through any hoops or installing software.

I guess swearing isn't aloud here "Cactus Music" because the forum ate my last 2 messages to you

Now that I'm not as angry anymore! I'm in a band and we have a bunch of old music and we dont have the originals anymore "stems" We are a bit progressive and would be easier for us to use software as a memory jogger to relearn the instruments

OK sorry, you can sort of see where I was coming from being your an actual musician. I thought it was yet another post by someone ( a none musician)  hoping to magically convert a stereo wave file into all it's original multi track parts. 
There is a way to export "stems" from sonar projects. It's in the export dialog where you can export a song as each track to it's own wave file.

I accept your apology Thank you. I know how to export stems lol We have our songs compressed to wav & mp3 but cleaned our computer to do a fresh rebuilt and no longer have the stems.

Vocal removers usually work with stereo material only. They reverse the phase of one channel and remix to mono.
This causes anything that had equal signal in both channels to cancel out.
 
More sophisticated versions allow you to bypass bass, because bass is usually also mixed to the middle.
 
There is also clever software that manipulates percussive instruments. It works by assuming all frequencies that have the same or similar loudness envelope must belong to the same instrument.
 
Melodyne can separate out notes of a chord played by the same instrument.

I guess theoritically it is possible, but in reality it's not practical.
 
An FFT analysis on the tracks would give you everything split up into individual sine waves. Theoretically, you could then choose which sine waves to put back in to the reverse FFT for each instrument and (assuming you've identified the right ones), repeat the process to give you separate tracks.
 
But you're talking of 100's if not 1000's of sine waves, PLUS the transients. So I doubt even if you could identify the right sine waves for each instrument, that the resultant tracks would be of decent quality.
 
The best you could hope for would be to maybe change the balance of each parts, but it would take you forever to get to that stage.

I doubt you'll be able to clearly separate the instruments.
What MIGHT help is putting harsh EQ settings.  For the bassist, roll off the treble and boost the bass.  For the guitars, cut off the high and low end.  etc.  Find the general frequency range for each instrument you want to identify, and make a separate WAV/MP3 for each range.
I expect that's the best you'll get.

Re: QUESTION. How to Split a recording for export as separate tracks or 2017/12/15 22:55:49 (permalink)
I had once the same question, because I wanted to separate the drum instruments of my old recordings, i.e. I had only a stereo track for the drums.
With some search on the internet I found a very cool FREE tool:
ISSE -  interactive sound source separation editor
 
It is not 100% perfect, but with some work you can really separate sound sources contained in a stereo wave file. You have to cut out one instrument after the other from the remaining audio. ISSE is very amazing and free! Have a look!
 
P.S.: By the way I have also tried with the Melodyne Editor. They make a lot of advertising about their separation and this software is not cheap, but it cannot really separate different instruments! Not even the kick or snare can be separated on a stereo drum track. I was really disappointed!
The only thing that I could do with it was to separate to choir voices that I had in a mono track.
