Make a DJ Intro Edit (Club-Ready, No DAW Needed)
A DJ intro edit is a shortened, beat-clean version of a track's intro built for smooth mixing — usually 16 or 32 bars of clean rhythm before the vocal or drop hits. You can build one in your browser in about five minutes: trim the intro, crossfade it into the track, normalize the loudness to a DJ-safe level, and export. No DAW, no upload, no account required.
Why DJs Build Intro Edits
Radio edits and album versions rarely mix cleanly — vocals come in too early, intros are too short to beatmatch, or the energy jumps before you're ready to bring the next track in. An intro edit fixes that: clean 16/32-bar rhythm section up front, so you (or Serato/rekordbox/Traktor) have room to match tempo and phrase before anything vocal or melodic kicks in.
The Workflow
Step 1: Trim the raw intro
Use the Audio Cutter to isolate the section you want to extend or clean up — usually the first 30-60 seconds before vocals or the main melodic element enters. Drag the waveform handles to the exact bar, not just roughly "close enough" — phrasing matters more than duration here.
Step 2: Check the tempo and key before you edit
Before crossfading anything, run the clip through the BPM Detector and Key Detector. Confirms the exact tempo for beatmatching and flags if the track's in a key that clashes with what you're mixing it into.
Step 3: Loop or extend the clean section
If the natural intro is too short (some tracks give you 8 bars, you want 32), you'll need to extend it. Use your DJ software's looping tool, or stitch a loop back-to-back.
Step 4: Crossfade into the full track
Join your extended intro into the rest of the track with a smooth crossfade so there's no audible seam. Use the new Audio Joiner & Crossfader to stitch the intro and body together seamlessly right in your browser.
Step 5: Normalize to DJ-safe loudness
Run the finished edit through the LUFS Analyzer and normalize to around -8 to -6 LUFS for club systems (louder than streaming-standard -14 LUFS — club rigs and DJ mixers expect more headroom-eaten level). This keeps your intro edit from sounding noticeably quieter than the rest of your set.
Step 6: Export and check on your actual gear
Export as MP3 or WAV depending on your setup (WAV for CDJs/USB, MP3 fine for most digital DJ software). Test it in your actual mixing software before your set, not just in a browser preview — phrasing that looks right on a waveform can still feel off in practice.
FAQ
How long should a DJ intro edit be?
Most DJs aim for 16 or 32 bars of clean intro — enough to beatmatch and phrase-match comfortably before the vocal or drop hits. Shorter than 16 bars and you're rushing the mix; longer than 32 and you risk losing energy.
What LUFS should a DJ edit be normalized to?
Club and DJ-set audio generally sits around -8 to -6 LUFS integrated, noticeably louder than the -14 LUFS streaming platforms target. This matches the loudness of commercial DJ pool releases so your edit doesn't sound weak next to other tracks in your set.
Do I need a DAW to make an intro edit?
No — trimming, crossfading, and loudness normalization can all be done directly in the browser with no software install. A full DAW (Ableton, Serato Studio, etc.) gives more control but isn't necessary for a basic intro edit.
Can I do this on my phone?
Yes, as long as the tools are browser-based and don't require desktop-only plugins. Trimming and normalizing both work on mobile Safari/Chrome.
Is it legal to edit a track like this?
Personal/DJ-use edits for your own sets are common practice in the DJ community, but redistributing edited versions of copyrighted tracks publicly may raise licensing issues — this guide covers technique only, not licensing advice.
