Edit Pro: How to perform beat-matching between songs
The following
procedures can be used to "fade" the tempos of two songs together
for a cool transition:
- Make
sure your lead-out song ends on a beat, and highlight the last 4 beats
(or 8 beats, or some nice division) and press F8 to add the selection
to the cue list. To help find the onsets of beats, use the Shift+[
and Shift+] keys (Edit->Find Beats->...).
- Do the
same with the first 4 or 8 (the same as the number of lead-out beats)
with the beginning of the lead-in song.
- Write
down the length of the lead out selection, and the lead-in selection
(eg lead-out=3.279, lead-in=4.488).
- Highlight
the lead-out portion of the first song (switch to Edit View) and go
to the Stretch transform. Choose Glide Stretch, High Precision, Time
Stretch, and 'choose defaults'. Initial%=100, Calculate Final% by
100*lead-out/lead-in (eg 73.06%).
- Next
go to the second-song (eg F12 to multitrack and double-click on the
second song), and highlight the lead-in section (hit F12 to go back
to edit view) and go to do another Glide Stretch (shortcut=F2 for
this). Calculate Initial% by 100*lead-in/lead-out (eg 136.87%). Final=100%other
settings identical).
- If you
have cue-snapping turned on (right-click on ruler to enable) you can
ensure the waves snap together.
- Finally,
you can highlight both waves in the overlapping region and right-click
to choose Crossfade->Sinusoidal.
If you
selected the exact same number of beats for both songs, each beat should
line up perfectly in time even though one song is slowing down while
the other is speeding up.
It's a
lot of steps, but with hot key access, and a calculator (try our free
RPN calculator in the Free
Stuff page at our site) you can start to do this pretty quickly.
