Feel & analysis
Liveness
Liveness describes whether a recording was made in front of an audience — a live set, a concert cut, a room recording. Some software scores it automatically; either way it tells you a track will behave differently.
In practice
Live records drift, because people played them. Ride the pitch or keep the blend short — a fixed grid will not hold.
Spot one in ten seconds: crowd under the intro, a room tail on the snare, and a waveform that never quite settles into a repeating pattern. Then treat it accordingly — analyse it with dynamic or flexible gridding rather than fixed, expect to correct with the pitch fader rather than trusting sync, and plan a shorter overlap than you would with a studio track. Where a live cut is the record you want, mixing out of it into something tight is easier than mixing into it, because you can hand the beat over rather than chase it.

Where these come from: How live recordings behave and what to do about them — practice, not a setting. Some software reports a liveness score, and ours is not one to rely on: not one of 445,032 analysed tracks reads above the 0.8 threshold that would mean "live", so we do not publish it. Your ears find these in ten seconds anyway. For what we can measure, see what a moving tempo does to a grid.
Why it matters
A live recording is the hardest kind of track to mix and the reason is not the crowd noise. It was played by people, so the tempo moves — a fixed beatgrid fits the first minute and slides by the third, and a blend that started locked ends a beat out with nothing obviously wrong on either deck.
The room comes with it too. A live recording carries the sound of the space it was recorded in, and that reverb sits underneath everything you mix into it, which is why a live cut and a tight studio record rarely sound like they belong together even when the tempo behaves.
Frequently asked
How do I spot a live recording?+
Crowd noise under the intro, a room tail on the drums, and a tempo that will not sit still on a fixed grid. All three are audible in about ten seconds.
How do I mix a live track?+
Analyse it with dynamic gridding, correct with the pitch fader rather than trusting sync, and keep the overlap short. Mixing out of it is easier than mixing into it.
Why does my beatgrid slide on a live record?+
Because people played it and human tempo moves. A fixed grid assumes a constant tempo, so it fits the start and drifts from there.
Related terms
Beatgrid drift
Beatgrid drift is a grid that lines up at the start of a track and slides out of alignment later — the tempo the software stored is close to the real one but not equal to it.
Click track
A click track is a steady metronome pulse a performer plays along to so the recording stays at a fixed tempo. Music recorded to one has a constant BPM; music recorded without one drifts.
Pitch riding
Pitch riding makes continuous small corrections to the pitch fader to hold two records in time by hand, rather than nudging the platter. It compensates for drift over a long blend.
Acousticness
Acousticness describes how much of a record was played rather than programmed — a piano, a guitar, strings, a voice in a room. In a club catalog it is rare, and the rare ones are unusually useful.
