Why You Should Record and Listen Back to Your Sets.

Why You Should Record and Listen Back to Your Sets

Why Recording Changes Your Progress

When DJing, your attention is divided between the playing track, the next one, levels, cueing and the crowd. It is impossible to hear the mix as someone standing in front of you hears it. That is the irony of the job: you are the person who hears your set least clearly.

Recording breaks that trap by separating two moments that happen together live: performing and evaluating. While mixing, you cannot judge; while listening, you cannot change anything. That separation is precisely what makes learning possible.

The academic framework of deliberate practice describes it this way: expertise comes from sustained effort with specific goals and feedback about what you have done, rather than accumulating hours. In DJing, the recording is the feedback. You set the specific goal, such as “this week, make the entries land on the phrase boundary”, and the recording tells you whether you achieved it.

Without a recording, your memory of the set is a reconstruction: you remember the transition that worked and forget the three that collided. With a recording, you have evidence.

What You Can Record in Each Software

Before establishing a routine, know what your software actually allows, because documented differences surprise many people.

In rekordbox, recording has its own panel with these documented elements: source selection, recording-level adjustment, level indication, start/stop button, and elapsed and remaining time for continuous recording.

The important detail is the source. The manual warns that EXPORT mode can record only the audio input from connected external equipment. To record rekordbox’s master output, use PERFORMANCE mode’s recording function, selecting [Master Out] when recording with the internal mixer. In other words, if you are in EXPORT expecting to record your internal mix, you will not record it.

For the file, the manual says the recording is created as WAV and saved in [Recordings] within the browser tree. The official FAQ specifies WAV at 44.1 kHz and 16 bit, adding that the physical destination folder is changed through [Location of Files] in Preferences, whose path varies by mode.

There are also two documented practical aids: automatic file separation when silence is detected, intended for digitising vinyl with gaps between tracks, which the manual warns can fail both when there is no silence and when a track has a very quiet passage; and automatic file splitting. The official FAQ sets a maximum of 3 hours per file: beyond that, the file is saved and recording continues in a new file.

In Traktor Pro 4, recording uses the AUDIO RECORDER and is configured on the Mix Recorder page in Preferences. To record the mix, choose the Internal source, which takes the internal master output, and set the destination directory and the size at which files are split automatically (the manual gives a maximum of 2048 MB). The panel includes a level meter, a recording-gain knob and a CUT button that closes the current file and begins another without interrupting the audio.

An honest caveat: the Traktor Pro 4 manual I consulted does not document the recording’s file format, sample rate or bit depth. So I do not assert them.

Recording Level

This is the most common mistake and the easiest to avoid. The rekordbox manual describes it precisely: if recording level is too low, files will be noisy and sound weak; if it is too high, clipping occurs and the sound distorts. It adds the adjustment criterion: the best quality is obtained by raising the maximum level to the point where not all indicators reach the red zone.

Notice the wording, because it matters: it does not say “set it to −6 dB” or “never reach 0”. It says to raise it to the threshold where the indicators are not all red. This is a criterion, rather than a universal number, and depends on your equipment and what you will do with the file.

The underlying reason is that digitally, 0 dBFS is the ceiling: there is nothing to record above it, and the signal is clipped. In the analogue domain, there is no such abrupt ceiling, but a nominal level with a margin above it, or headroom, where the signal gradually compresses and saturates. Traktor describes clipping in those terms: the signal clips when it exceeds both nominal level and headroom, then starts distorting and loses dynamics and punch.

Traktor Pro 4 also documents a dedicated recording-gain knob and refers to its level-optimisation section. rekordbox offers an adjustment to optimise a recorded file’s audio level automatically. These are aids, not substitutes for watching the meter.

For more detail on the mechanism and the distinction between digital and analogue, I cover it in Gain staging for DJs and Is DJing in the red bad?

How to Listen to What You Recorded

Recording without listening achieves nothing. Listening poorly achieves little: with only a quick pass, you will hear what you already knew.

What works is separating two listens with different purposes, a practice DJ schools describe as “casual listening” and “listening as a DJ”. In casual listening, play the recording in the background while doing something else, as an audience member might: you notice whether the overall set engages, whether something becomes tiring or whether a section drags. In analytical listening, have the track in front of you, a stopwatch and notes about specific moments, and review what you did in each transition.

This is a school’s educational proposal, not a technical standard: treat it as a heuristic. What the deliberate-practice framework does support is that the second listen needs specific goals. “I will review the first four mixes and note which bar each one entered on” is useful listening. “I will listen and see how it was” is not.

One detail helps greatly: note the exact timestamps of questionable moments as you listen. Returning to a specific minute is far more productive than listening through twenty minutes again.

What You Miss When You Do Not Record Yourself

What follows is booth experience rather than manufacturer documentation, and it is the part that really changes things.

Recording and listening at another time and from another perspective reveals most mistakes: overused microphone phrases, too much or too little effects, volume-level problems and, generally, all the artistic mistakes a set carries. You miss them live because you are inside it.

There is a specific reason: alcohol or other substances and show adrenaline distort your perspective while performing. What seems a brilliant transition at the time may sound disastrous three days later, and vice versa. The recording is the only version of the set uncontaminated by how you felt that night.

Not everything you discover is negative. Listening also helps identify what you did well, such as an entry, a cut or an effect at exactly the right moment, so you can repeat or replicate it deliberately rather than by chance.

One particularly informative resource is recording ambient sound, with an open microphone in the room. You can check which songs the audience reacted to and which they did not, with timestamps in front of you. It is the difference between remembering that “people were dancing” and knowing that the track that lifted them arrived at 01:20.

Dead spots are the kind of discovery that appears only on a recording: stretches where the set neither advances nor retreats, mixes that hold without deciding, transition silences that seem endless, or moments when the set sounds on autopilot. They pass unnoticed live because there is always something to do; on playback, their duration exposes them. Note the exact minute and likely reason, such as lack of judgement, an energy dip or waiting for a drop, and decide whether it was a planned valley or a real dead spot.

Warning: this cuts both ways. Listening from a distance can crush you if it becomes a judgement of yourself. The aim is not to discourage you, but to gain an advantage over your competition: almost nobody reviews sets methodically, and someone who does advances faster than someone who merely accumulates booth hours.

A Sustainable Recording Routine

The routine that lasts is the one that takes no extra effort:

• Press record at the start of every practice session, rather than only when you think you will do something good. Interesting mistakes appear when you are not looking for them.
• Give the file a recognisable name and date so you can compare weeks.
• At the end, note three moments: one that went well, one that went badly and one you cannot judge. That is your listening plan.
• One casual and one analytical listen to the same recording, at different times.
• One fix per session. Choose a single aspect, such as entries, EQ use or selection, and work on it the following week; this is more effective than trying to correct ten things at once.

Those three moments noted at the end are the beginnings of a form. When several sets accumulate and you want to know whether a specific mistake still recurs or has been corrected, that form has its own structure in the DJ set self-critique checklist.

With the software’s own tools, this routine is inexpensive: in rekordbox, recording ends up in [Recordings] within the browser, and in Traktor in the recording folder you set in the Mix Recorder directory.

Common Mistakes

Recording only “good” sets. The opposite is true: ordinary sets reveal your habits. Exceptional moments do not repeat.

Recording in EXPORT and wondering why nothing is audible. The manual warns you: EXPORT records only external input. For the internal mix, use PERFORMANCE with [Master Out].

Recording without watching levels. The manual is explicit about both consequences: low level means noise; high level means clipping and distortion. The recording cannot be recovered afterwards.

Accumulating recordings without listening. Recording is half the method. Without listening, you have merely backed up your mistakes.

Listening for validation. If listening is meant to confirm you DJ well, you will find nothing. Useful listening seeks the uncomfortable moment.

Confusing recording with practice. Deliberate practice needs a goal and feedback. Recording provides feedback; you set the goal. To turn listening into a work plan, continue with How to analyse your own set and identify mistakes.
