Topic: Audacity (osx): How to mix two AUD sources?

[justink]

The trouble with the math method is that it assumes the drift is at a constant rate.  In my experience this is never the case.

New audacity won't allow you to do it anyway.  I used the "sample" instead of the "speed change" option.  it's under the same tab as the speed change.  but you have to change the bottom numbers to samples instead of time. 

that's the best i can help with this thread.  it's the same idea but using samples instead of the "speed change" window.

try it out, 'undo', try again until you get it right.

Like I said... this should be an easier fix... drag and drop.  but i'm confident in the sample tequinique.  just takes math and figuring it out...

Oh yeah audacity changed everything at least once.
See my current calculator spreadsheet which allows you to figure the new total length of the section you want to change, and enter the precise number IN SAMPLES

I think my spreadsheet should work fine for the new system, because you can enter the total length in samples of your file to be stretched/squashed in samples, and the math spits out the new length you need, also expressed as samples.

Having issues for the first time in doing this, I've never had to deal with "drift" until my latest recording. I see that calculations spreadsheet posted, and I have no idea what I'm looking at there. Is there a simple (like I'm a 5 year old) explanation, or any other alternative methods, programs, etc?

The easiest way is:

1) Trim each source so they start and end on the same sound (start of a drum hit, guitar strum, anything well defined)

2) Select one source in its entirety and write down the endpoint (second number) under Selection

3) Select the other source in its entirety and select Effect > Pitch and Tempo > Change Speed and Pitch

4) Change "New Length" to the length of the first source.

If it still doesn't sound right, eyeball the two waveforms near the start and end — you probably messed up Step 1, which is easy to do, so go back and try that again, then redo the other steps.

I somehow managed to make it even worse, I guess it just wasn't meant to be.

Nevermind, figured it out!

Yep, that's how it usually goes for me!
