Possible to make an audio track fit an exact tempo after the fact?
I've got an audio track that doesn't fit any exact tempo. Is there an
app that will adjust it just a hair here and there to make it conform to a specific tempo? The tools I have now are Cakewalk Home Studio 2 and Soundforge 5. Thanks |

It will sound pretty good for small adjustments, absolutely terrible if you try to stretch too far :-) Or does the track have sloppy tempo and you want to align it with e.g. a mechanical drum beat? |

It's supposedly even more robust in the newest version (8), and since you're already a Cakewalk user, it may make sense to look at the upgrade path. Corey http://www.curbsideproductions.com/ |

I wouldn't call the tempo sloppy, but it drifts just a tad so that no metronome marking will be exactly on the beat throughout the track, even using incremental adustments. The best I've been able to do is have it be off by no more than about a half beat either in front or behind as it drifts over the duration of the track. I suppose I could take the track, determine where it starts to get off, stretch/squeeze part of it, compare, adjust etc. |

Live performances can be like that. It can let the music breathe, which is good. It can be sloppy playing - a simple inability to hold the beat - which is bad. If it sounds OK by itself, what's your reason for wanting to align it to a strict beat? Are you hoping to add rhythm tracks in a sequencer? It may sound better if you stretch the tempo map rather than messing with the audio. Cubase 4 has a tool that does this easily, I'm sure the other high-end DAW programs do too. |

The tools I have now are Cakewalk Home Studio 2 and Soundforge 5. Thanks I assume this is a live performance you're talking about here? And I further assume that other than the tempo variations, there is nothing else you want to change with the recording? Can I then ask why you think it is so important that a live performance be straight-jacketed into an exact tempo? All live performances have some ebb and flow in the tempo - this is a natural consequence of it be performed by humans. Though I haven't heard the track, I'd say leave the recording alone and adjust the tempo in Cakewalk to fit the natural changes in the performance. Failing that, buy Melodyne Studio and time shift it there. £0.025 Chris W -- The voice of ignorance speaks loud and long, But the words of the wise are quiet and few. --- |

The tools I have now are Cakewalk Home Studio 2 and Soundforge 5. Thanks You could try 'abletonising' it. Load the audio into a clip slot in ableton, and set the 'warp' function to 'complex'. Ableton will then warp it 'in time'. It's not like doing it on the 'beat' function which is for rigid tempos, so should work. Trouble is, a) you'd have to buy ableton, and b) as has been said, doing this at all is likely to rob the recording of it's essential 'life'. I've always found it amazing how counter intuitive this is. I've tried it many times, and manually or otherwise tightening up sloppy timing always results in a worse product than before. You think, 'this'll sound even better if I can just fix this bit here...and just doing this bit here...and...oh. It sounds terrible. Cheers, Doof. |

I'm doing a project where I'm adding horns and backing vocals to an existing track. I'm working the parts out in midi first and in order to have the resulting parts be readable when printed, it needs to be at a specific tempo. |

In that case, I would use the time-warp function of the DAW software to align the bars/beats to the audio, not the other way around. Jos. -- Ardis Park Music www.ardispark.nl |

See my previous reply. By "Tempo Map" is that a specific function or are you basically referring to the act of tweaking the midi tempo - make it be 83 for X- bars, 85 for x-bars and so on to make it line up with the audio? I.e. stretching and squeezing the midi instead of the audio? Part of the problem with that is doing it precisely. I don't seem to be able to use the metronome function with the softsynth I'm using to produce midi sounds. I've already kludged together the audio to fit close enough but it's actually not imperative that the audio "flow" well on the project track, since the immediate goal is to produce readable parts. For now, the audio is simply a guide. Then I can record the vocal & horn parts to the unmolested track in another project file. |

I don't seem to be able to use the metronome function with the softsynth I'm using to produce midi sounds. I mean both. What you describe is the result - the better sequencers have tools and functions to make it easy. I've already kludged together the audio to fit close enough but it's actually not imperative that the audio "flow" well on the project track, since the immediate goal is to produce readable parts. For now, the audio is simply a guide. Then I can record the vocal & horn parts to the unmolested track in another project file. If you're constructing the arrangements by playing along with the audio track using MIDI sounds you'll find it much easier to play good stuff if the audio groove remains unmolested! Unless you play in a thoroughly stilted and unmusical fashion there's going to be a lot of editing needed to produce a playable score. You might get a better result by composing without worrying what the notation looks like then, having done the hard bit - deciding WHAT the arrangement is - do the easy bit separately - transcribe it as notation. I think advanced sequencers offer audio quantisation as well as MIDI quantisation. But if you had one that did that, I guess you'd have found it in the manual? |

Sure, it has a quantize function but even so you have to be in the ballpark for it to work. It doesn't have any way of knowing that notes are half a measure or more off from where they're supposed to be, it would just make a mess. |

I meant the audio quantisation, where you tell it where the beats are and it stretches the audio into alignment. Not that I've found such tools sound very nice, particularly on a full mix. |

Well, that was essentially my original question, if there is such a thing. As far as I can tell this version of Cakewalk doesn't have anything that sophisticated. What I ended up doing was stretching/squeezing the track in Soundforge and got it to where it's close enough. There are a few artifacts in the sound but not enough to get in the way of what I'm doing. It wasn't off so much that it really makes a big difference in the audio but enough so that midi parts created to the original audio couldn't be printed usefully. Now when I play the live horns and do the vocals I can just self- compensate to the track. I don't think a human could tell the track is off at all, it's only obvious when you compare it to the exactness of the software environment. |
