Hi
How do I sort out the tempo about the song in Audacity? I don`t have any menu for that.
I just tap my foot and count for 30 seconds or a minute.
To make counting easier, I count 1-2-3-4, 2-2-3-4, 3-2-3-4… It won’t be perfect and it might be difficult if you are trying to synchronize with a pre-existing track, or MIDI track. (It’s no problem for a human to synchronize.)
Sometimes the tempo will drift over the length of a song. Sometimes intentionally and sometimes unintentionally. Most modern music is “locked down”… Recorded with a click-track or MIDI generated. But you usually don’t know the exact tempo unless you count-through the whole song.
