Audacity 2.0.5 on Windows 7 - 64 bit
The purpose: to add “click track markers” exactly on the same beat as the recorded music.
I want to write down recorded music on a music sheet/ note notation.
To do that : I have to define the notes by ear and then determine the duration of the notes and rests
So, if I have a “click track” following the exact beat of the recorded music, than I can tell exactly where a specific note is played and the time duration ( whole note, ½ note , sixteen note etc…).
First I need to know the exact tempo of the recorded music.
Sometimes there’s a beat indication/tempo given by the drummer at the start of the recording, like here for example:
This is a backing track: https://www.youtube.com/watch?v=QRxiiV8C4wM
This is the backing track with music : https://www.youtube.com/watch?v=uNKxG83L7CY&list=RD02wmZSTYFtYWo
Is it possible to put the “click track markers” exactly on those beat signals without knowing the exact beat per minute. Or i.a.w. can I manually put the “click track markers” on top of the beat signals ?
Or… do I first have to define the beats per minute of the recorded music, with a metronome and then chose the beat per minute on the click track menu?
The problem , how to put the “click track markers” exact synchronized with the beat, is still the big question…
Anyone with a solution ?
(PS: apologies for my English, isn’t my native language)
You can detect the beat by ear. Most pop music has a 4/4 time signature, so put the cursor in Audacity at a strong beat and select an area of track containing four quarter-note (crotchet) pulses (that is, an area up to the next strong beat). Note the length of the selected area in seconds as given in the Selection Toolbar at the bottom and divide it into 240.
For example, if you find the four beats take 2 seconds, 240/2 = 120 BPM. If you have a 3/4 track like a waltz, divide the length into 180.
Alternatives: This browser-based tool allows you, while playing your track, to tap any computer key to the the beat and the BPM will be displayed:

Once you know the BPM you may wish to generate Audacity labels at each beat:
Thanks for the answer.
I’ve already used such a " beat finder" by tapping in the past, but yours can be downloaded … so much more convenient.
A quick look at the other links tells me that there is more or less a solution for this item via a detour and maybe a “real” solution in the future .
Meanwhile, I’m gone dig in to the " detour" and I’m sure your advice will bring me to a solution.
Kind regards ,
Note that music that is played by real people (not by computer) rarely stays at exactly one tempo. The example backing track that you posted is about 124 bpm, but because of the natural swing and feel in the music, it is sometimes a little quicker and sometimes a little slower.
