I tried the following method out on A Winter's Tale - maybe I didn't line 'em up properly, but all's it did was eliminate John Deacon's bass playing. Feel free to try it yourselves though, we need more good a capellas! The following comes from some site I just googled. If you put in 'a capella "invert waveform"', it should be no. 1 on the list. ---------- You want an acapella of a track but you just can’t find one anywhere. Why not do it yourself? there is a simple trick that you can try if there is an instrumental version of the same track released. Step 1 : Instrumental Version Find an instrumental version of the track. CD Singles are the best source, as the digital recording & pressing techniques are more likely to give a perfect copy of the backing track, which is something that you need. MP3’s are not likely to give good results as the compression method removes some of the audio data that may be required. Recording from vinyl may work if you do both recordings under exactly the same conditions (any pitch variation will reduce the effectiveness of this technique). Just rip the audio tracks to wav files, or another uncompressed format, .AIF etc, using an Audio Extractor/Ripper. The basic idea relies on the linear superposition of audio. Which is simply: that if you take a sound, any sound at all, and add it to the inverted version of itself the result will be silence. Note: Occasionally the instrumental on the CD Single will have a slightly different arrangement or structure. basically you are screwed in this case. (it won’t be this simple but you may be able to salvage something). A rough guide when you’re considering buying that CD single is “Are the two tracks exactly the same length?” if they are, then there is a good chance the engineer just muted the vocal track when they did the instrumental, which could result in a nice clean acapella. Step 2: Matching Them Up Now that you have the Instrumental Version its a matter of matching the two songs exactly. i.e. to the sample. The best thing for this is a wave editor like Soundforge, Peak, Cooledit,......etc Radio version vs. Instrumental As you can see these two look pretty close except for the vocal sections. That’s a good start. By zooming in on the first beat of the Radio Version you get a better picture of the shape of the waveform. You want to find a distinctive little waveshape that you can then look for in the instrumental (or vice versa). for example I just focused on this little click at the beginning of the track: Find a Distinctive Waveform Shape After you find the same section in the second track you can start trying to line them up so that the spikes fall on EXACTLY the same sample position. Personally I just delete sections from the beginning of either until the sample no. readout of the spikes is exactly the same. This makes it much easier to do the “paste mix” later. Match Up the Two Tracks Step 3 : Mix ‘Em Together The rest is rather simple, just invert one of the tracks, say the instrumental, (“Select All” then apply an “Invert Waveform” function or similar) and mix the inverted instrumental with the original aligned radio version the result may be a pretty clean acapella. to Mix the two: In Soundforge I just select the entire song (try and find a “Select All” command). Now copy that into the clipboard. i.e. just Copy it. (“Ctrl + C” or “Option + C”). Select the other version from the beginning of the track and PASTE MIX or similar type function. You may need to fiddle with the respective volumes of the two as there may be differences in the mastered loudness. That’s about it. The idea is that now that they are aligned it is very easy to do a paste mix where the two waveforms will fall directly on top of each other (but inverted) and hence cancel out. This will leave only the difference between the two (the vocal) Although there will most likely still be some resemblance of drums and stuff throug |

I tried this method with the Karaoke CDs, and whether I was doing something wrong, I don't know, but it didn't work at all. All I got was an unpleasant phasing effect throughout. It's certainly not something worth posting on here. I couldn't actually work out how to visually 'layer' one track over the other, in Sony Soundforge, so used the Mix Paste tool, which is pretty accurate usually. |

"So why didn't you post the result? I have a pretty poor imagination - especially when it comes to music!" Heheh - sorry about that. But really there is nothing to imagine in this case - the beginning of the song sounds pretty much unchanged, but the bass at the start (the high one) is pretty much gone. So I dunno, if there was a market for "Bass Karaoke" where bass-players get to play along with the track minus bass parts... I guess I'm onto something. |

What program are you doing this? I try to delete the audacity to identify himself sound vocals. Sometimes something is successful and sometimes not. And some of you did anything at all? As anyone even decently done, please send and share your accomplishments. I greet you! |

I wish there was a way to get the acapella vocal for 'Ride The Wild Wind', and mix it with The eYe version. That version kicks the Innuendo versions ass! |
A Word In Your Ear 31.05.2011 05:50 |
Not tried doing it yet, but I'll give it a go in Adobe Audition, but it will be the first time i've tried doing it, so i'm not hoping for much!!!! Think I'll have to pay "Youtube" tutorials a visit, to get my head around it. lol!!!! |

"bambams-paradise wrote: I wish there was a way to get the acapella vocal for 'Ride The Wild Wind', and mix it with The eYe version. That version kicks the Innuendo versions ass!" Yeah, that version rocks! But I think there is no need to remove the whole backing track to extract the vocal if you want to mix it with the eYe version. It can be simply masked using the instrumental track which is very similar to the original album version. It's impossible to remove everything except the vocal but for mixing with The eYe version it can be sufficient. I will take a look at this closer ;-) |

I tried a couple things with Adobe Audition last night for a few hours, and didn't get too far. I had the idea of mixing the two sources together as well, but being that I'm not all that good with this stuff, I had zero luck! I did create a couple of kick ass samples, making part of the guitar solo go backwards and putting some delay on it and the such...sounded pretty cool...I dunno if anyone would wanna give that a go either...just a thought. This song, if anyone had the multitracks for it, could be alot of fun making a mix for it, because it's fairly repetitive throughout the song and alot of things could be done with it. The drums and bass in The eYe version are just so much more in your face through the whole song than the regular version imho. |
PiotreQ 01.06.2011 04:12 |
OK, here's just a quick mix I made. (Almost ;-)) acapella + the eYe instrumental version blended together and some EQ work etc. Soon I will probably mix it again and try other things for better effects ;-) link |
A Word In Your Ear 01.06.2011 08:46 |
Tried Adobe Audition myself last night. I tried using the Karaoke version of Radio Ga Ga & the normal version, I think the tempo was slighty out, so it didn't work. Then I tried using Rogers "Unblinking Eye" 2 tracks from the same cd should match right? Inverted the instrumental track, got all the high & low peaks matched up & guest what?......It didn't work. must be something I'm doing wrong...... |
GinjaNinja 01.06.2011 11:32 |
I doubt it will work with any of the Karaoke versions, due to the fact that they have been re-mixed from the multitracks. However close it may sound, it is going to be different from the original mix and even if lined up perfectly, the waveforms won't be the same. With Pro-Tools and automation these days, I would have thought that the Unblinking Eye one would work. This indicates that they haven't simply muted the vocal track, and have altered the mix slightly to compensate for the lack of vocal. You need perfect conditions for this to ever work really. |

Awesome job with the Ride The Wild Wind mix! About as good as could be expected for what there is to work with! :~) |
PiotreQ 02.06.2011 14:26 |
Thanks, nothing special, just a quick mix with some EQ works but like I wrote earlier, some day I'll try to create something better :-) |
Back2TheLight 02.06.2011 18:22 |
Hey for what you had to work with, it's pretty damn good! |

It's one of these things that only work in theory. It's like muting a signal 100% by putting the same signal on top of it, out of phase. Anyone who worked with recordings knows a full cancellation SHOULD occur, but in practice it never happens. |

I tried to isolate the voice on Too Much Love Will Kill You but the result was not good. The voice was prominent, but the instruments are still in the background, especially the guitar Here is the result: link And I was also trying to get new sounds from the official DVDs, (DTS 5.1) I extract an interesting end of the song The Miracle, where only Roger and Brian sing the part "The time will come ..."
