DJ guides you can put to work tonight
BPM, key, Camelot, file quality, and how to organize a library. Each article answers one question DJs ask a lot, short and with examples.
What is the Camelot wheel? Harmonic mixing for DJs
Camelot writes musical keys as a number and a letter, like 8A or 11B. Learn three simple moves and you can mix in key, no music theory needed.
BPM & keyHow to find the BPM of a song, fast and accurately
BPM is the number of beats in a minute. Tapping along works for one track. For a whole library, you need software that detects it for you.
BPM & keyHow to find the key of a song for DJing
The key is the home note and scale of a track. Know it and two tracks won't clash when they overlap. By ear it takes practice, with software it takes seconds.
BPM & keyWhat is LUFS? Why some tracks sound louder than others
LUFS measures loudness the way the ear hears it. Two tracks that peak at the same level can still be several LUFS apart, and one clearly sounds louder.
Audio qualityHow to spot a fake FLAC or an upscaled 320 kbps MP3
Changing the extension or converting the format doesn't make music sound better. One look at the spectrogram shows whether a file has lost its highs to compression.
Audio qualityHow to read a spectrogram to check audio quality
A spectrogram is a map of sound: across is time, up is frequency, color is strength. Once you're used to it, one glance tells you whether a file has a problem.
Audio qualityMP3 320 vs FLAC vs WAV: which format should DJs use?
On a club system, the difference between a good 320 kbps MP3 and a FLAC is tiny. The big differences are elsewhere: is the file really the original, do the tags survive, can the DJ gear read it.
Audio qualityWhat is clipping? How to spot tracks that distort
A clipped track sounds fine on headphones, then turns harsh and crunchy at its loudest moments on a big system. Know in advance, so you don't drop it at the peak of your set.
LibraryHow to organize your DJ music library
A tidy library isn't about looking neat. It decides whether you find the track you need in five seconds or five minutes, in the middle of a set.
LibraryHow to sort music by genre automatically
The Genre tag says "Electronic" on a thousand different tracks. To split them the way you actually play, the fastest way is to teach a computer with the folders you've already sorted.
DuplicatesHow to find and delete duplicate music files
One track downloaded three times, under three names. Matching by filename misses them, matching by size merges the wrong ones. To really clean up, you have to compare the audio itself.
TagsHow to batch edit MP3 and FLAC tags and rename files from tags
Clean tags mean your DJ software shows the right names, search finds the right track, and sorting by key is one click. Fixing tracks one by one takes an evening, in bulk it takes minutes.
Listening & EQEQ basics: how to make your music sound better
An EQ (equalizer) boosts or cuts ranges of frequencies. Done right, the bass is solid without boom and vocals are clear without harshness. Done wrong, it distorts.
Listening & EQWhat is key lock (Master Tempo)? Change tempo without changing key
Push the tempo up 6% and the track also rises about a half step, just enough to clash with the next one. Key lock keeps the key still while the tempo moves.
VisualsHow to make music visuals for videos and live shows
A looping background video that has nothing to do with the track gets scrolled past. Visuals that hit on every kick are a different story.
