Waveform
The waveform is the picture of a track’s level over time, usually coloured by frequency content. It is how DJs read a record’s shape without listening to it — where it thins out, where it lands, where it ends.
Measured in our catalog
How tall a track draws is only loosely related to how hard it hits: loudness and analysed energy correlate at 0.32 across 443,242 tracks.
A coefficient of 0.32 is real and weak — level explains about a tenth of the variation in energy. The catalog spans -85.23 dB to -2.80 dB with a median of -10.68, and 27,674 tracks are mastered hotter than −8 dB. So a fat waveform tells you about the master, and the shape — where it thins, where it steps — is the part worth reading.

Why it matters
A waveform is the fastest structural read you get. A wide block is a full arrangement, a narrow stretch is a breakdown, and the vertical step between them is the drop — none of which requires knowing the record.
It is also the most over-trusted display in the booth, because height is level and level is a mastering decision. Two records can look completely different and hit the room identically, and the number below says how loosely the two are actually related.
Frequently asked
What do the colours on a DJ waveform mean?+
They split the signal by frequency — blue or dark for the low end, orange or amber for mids, white for highs. A section that loses its blue has lost its kick and bassline, which is the thing you are usually looking for.
Can you tell where the drop is from the waveform?+
Usually. A thin stretch followed by a vertical step is a breakdown followed by a drop, and it is readable at a glance. What the waveform cannot show is whether the section is musically what you want to mix into.
Does a bigger waveform mean a louder track?+
In the room, not necessarily. Height is the master’s level, and level correlates with analysed energy at only 0.32 across 443,242 tracks — so gain-matching by eye is a starting point, not an answer.

Loudness
Loudness is a track’s average level in decibels below full scale, so every value is negative and closer to zero is louder. It decides how far you move the gain, not how hard the record hits.
Gain
Gain sets how hot a track arrives at the channel before anything else touches it. It is a correction for how the record was mastered, not a volume control for the room.
Beatgrid
A beatgrid is the map your DJ software lays over a track marking where every beat falls. Once it is right, sync, looping and quantise all work; once it is wrong, everything built on top of it is wrong too.
Memory cue
A memory cue is a saved marker you navigate to rather than trigger. It appears on the waveform and the player jumps to it when you call it up, without playing until you tell it to.
