Is there an app that does this?
I have a wav file of an acoustic guitar made by an old friend. What I need to do is get this into the same tempo as the rest of the track it's intended for, without it being mangled out of all recognition.
Perhaps I'm just not seeing it, but nothing I have so far on the iPad can do this job. Not Auria Pro (at least with supplied features) or Cubasis. I did try taking it into Logic Pro X on the Mac, but quickly found that the BPM Detector plug-in doesn't work for files without a beat. DOH.
I'm surely not the first person who wants to do this, so there must be a solution, right? Ideally, there's an app I can import the track into, which will detect it's BPM and allow me to dial up the correct one.

It seems that if you know the number of bars and the duration, that the BPM is a matter of mathematics, no? Whether the guitar is played in rhythm or in time is another story.

It's just a wav file, that I'd like to fit something around. ISTM that's what I'll have to do, as opposed to making it fit in with something else.
Well you could try Egoist, but it depends on the style of guitar playing a bit. You could then re-jig the slices to the correct tempo.
If you have a Mac, couldn't you take it into the Apple Loop Utility application and slice it there?
Rebuild your track with the correct timing or record another take with the guitar. Any other approach will heavily affect, in a bad way, the quality of your sound. Rate/pitch shifting will always distort your sound.

Yes, I have a Mac, and as Insaud earlier was trying to work something in the amusingly named Logic.
Will also be giving your idea a try,

Recording another take would be difficult, due to circumstances beyond my control. But thanks for your advice.
copy a section from the guitar track that you consider 1 bar and paste it into your project at any bar boundary.
Then you can tell by simple arithmetic how much the guitar deviates.
Stretch or shrink accordingly by a quality algorithm like Anytune, iirc Auria has similiar stuff included.

Thanks, will give it a go.
This sounds exactly like the solution to your problem.
If you know bpm of the recording and bpm you want then you can use the time stretch in Beatmaker2, you specify the original bpm and the bpm you want to stretch (or squish) to

Looks interesting. Will have a bash using this method, too. Thanks for info.

I'd forgotten I had Beatmaker2 installed. I don't know the BPM of the guitar .wav, but do know it for the track I'm trying to shoehorn it into. So, this is another possible route. Thanks for the post.
There are some free tap to calculate bpm apps out there you can use to work out the guitar bpm

I shall go in search. Thanks.
LPX Flex time should allow you to butcher it into whatever timing you like, Regular, or not (New Minty? Cheese and Sardine? Beer and Gypsum Dust?).
Looks like a job for ableton's warp fonction !

Thanks. Will download.

Alas, I have enough of a learning curve with AuriaPro and Logic Pro X, without adding another DAW.
You may have the best luck with chopping it into small sections (find chunks that are fairly steady) and the using time stretch in auria to deal with each little section. I've done that before with time stretch and it worked well enough. If the timing was consistent all the way through and just at the wrong tempo then it's easier but if it was inconsistent (beyond normal human variation) then dealing with small pieces at one time will give the best results, no matter what app you use.

You've got it - the flex time thingy in Logic Pro X.

Oh, so I have. The thing with Logic is, I find it highly illogical, and have to spend ages clicking around to get things going. But, I shall persevere, and hopefully eventually learn something.
Already onto this method, and spent ages chopping up likely sections. So far, quite promising. If not, I've imported them onto Blocs Wave, where I'm sure I'll be able to get something going.
Excellent, I look forward to hearing how it turns out. For what it's worth, I've done this kind of thing in reaper and found it easier than any ios app. I love auria for mixing and for straight out tracking (see my youtube video about recording from the x32 live), but not so much for editing or midi.
I love ios for music, but sometimes other tools are just better and no one cares how I achieved a result, just that I achieved a result at all.
Sounds like you're onto a workflow though, so make sure you provide some details.
You got a link ?
Edit: nevermind, i have found it !
Sorry, I didn't want to post it in someone else's thread, but glad you found it!
Do you know the tempo of the track it's intended for? If so, thank yes, Auria can help you (even the non-pro could), assuming you have some musical training:
P.S.: to have a head start in the process, tap tempo while auditioning the wav file - it will make the task incredibly easier.
P.P.S.: and, if you have Auria Pro, transient detection coupled with tap tempo can make it even easier!
P.P.P.S.: just did the experiment with a song I chose randomly. It took no more than a few minutes to insert a few transient markers and make it fit perfectly (tempo-wise, hehehehe) in a project of mine, also chosen randomly.
