Chapter 11: Synchronization
At most of today’s dance clubs and events, the DJ will mix the songs together using a technique called
beat-matching. The goal is to fade the volumes between two songs while keeping them perfectly in time with
one another. If done properly, the audience will never have to stop dancing as the beat of one song blends in
with the new song. DJ's will do this for hours at a time, creating one gigantic non-stop mix from the individual
songs they have in their collection. Proper execution of this technique requires the mastery of two tasks:
matching tempo and matching phase.
Automatic Tempo and Phase Detection
As mentioned before, tempo is the measurement of the speed of a song expressed in beats per minute (BPM).
Phase refers to the location within a song in reference to its downbeat. Torq automatically determines the
tempo and phase of a song when you load it onto a Deck, so matching tempos is as simple as moving the
Speed slider on a Deck until the BPM Display shows the same value as the other Deck. If you’re using external
vinyl or CD control, you can adjust the speed of the song using the turntables or CD player’s pitch adjuster.
Once you have matched the tempos of two songs, you need to start both songs at precisely the right moment,
or in-phase with each other. When beat-matching songs, you’ll normally want the downbeats of both songs
aligned with each other. When aligned properly, the beats of both songs will blend together into one larger
beat. If the songs are misaligned or out-of-phase, it will sound terrible as the beats of the two songs will be
playing at different times.
Torq’s scrolling waveforms in the Waveform Display will help you match the phases of the two songs. Not
only can you visually align the transients in the waveforms, you can also use the Phase Grid for automatic syn-
chronization.
Phase Grid Manipulations
Torq places a Phase Grid over the Scrolling Waveforms to help you see where the beats are, even during a
breakdown or “rhythmless” intro of a song. In order for the automatic synchronization to work, the Phase
Grid needs to be properly aligned with the music. With the Phase Grids of both songs aligned properly, Torq
will be able to sync the two songs together. Torq will attempt to place the Phase Grid in the proper location
during song analysis. If Torq positions the Grid incorrectly, it will be up to you to re-align it to the proper beat.
