Guide

Complete Guide to DJ Mixing and Looping

Understanding Dual-Deck Mixing

Dual-deck mixing is the foundation of DJing. Each deck plays a separate audio source, and the crossfader controls the blend between them. Moving the crossfader to the left emphasizes Deck A, while sliding it right brings in Deck B. Professional DJs use this setup to create seamless transitions, keeping the energy flowing without silence between tracks. The key is matching the tempo and phrasing of both tracks so the transition feels natural to the listener.

Mastering A-B Loops and Cue Points

A-B loops let you isolate a section of a track and repeat it indefinitely. This is useful for extending a breakdown, holding an instrumental section while mixing in the next track, or practicing transitions over the same passage. Cue points work differently; they are instant jump markers that let you skip to specific moments like a drop or vocal hook. Together, loops and cue points give you precise control over the structure of your mix and are essential tools for live performance.

Using EQ for Clean Transitions

Three-band EQ (Low, Mid, High) is one of the most important mixing tools. During a transition, gradually reducing the bass on the outgoing track while boosting the bass on the incoming track prevents the low frequencies from clashing and muddying the sound. This technique, called EQ swapping, creates clean and professional-sounding transitions. The mid and high bands can be used to shape the tonal character of each track, cutting harsh frequencies or boosting clarity as needed.

BPM Detection and Beatmatching

Beatmatching means aligning the tempo and phase of two tracks so their beats land at the same time. The BPM detection feature analyzes each track and displays its tempo, giving you a starting point. Adjust the speed slider on the faster or slower deck until both BPM values match. Then nudge the playback position so the downbeats align. Once the beats are locked, you can crossfade smoothly without the audience hearing any rhythmic clash between the two tracks.
Examples

Worked Examples

Example: Smooth Crossfade Transition

Given: Two house tracks at 124 BPM loaded in Deck A and Deck B.

1

Step 1: Play Deck A and let it reach the last 16 bars before the outro.

2

Step 2: Start Deck B and align its downbeat with Deck A using the cue point.

3

Step 3: Gradually cut the Low EQ on Deck A while boosting the Low EQ on Deck B over 8 bars.

4

Step 4: Slowly move the crossfader from Deck A to Deck B over the same 8 bars.

5

Step 5: Once fully on Deck B, reset the EQ on Deck A for the next transition.

Result: A smooth, professional-sounding transition where the bass never clashes and the energy remains consistent throughout.

Example: Creating a Loop-Based Mashup

Given: An instrumental track on Deck A and an a cappella vocal from YouTube on Deck B.

1

Step 1: Load the instrumental into Deck A and paste the YouTube URL for the a cappella into Deck B.

2

Step 2: Use BPM detection to check both tempos and adjust Deck B speed to match Deck A.

3

Step 3: Set A-B loop markers on both decks to isolate matching 8-bar sections.

4

Step 4: Use the crossfader at center position to blend both tracks equally and adjust EQ to taste.

5

Step 5: Click Export Mix as WAV to save the mashup.

Result: A custom mashup combining the instrumental and vocal tracks, exported as a high-quality WAV file.

Use Cases

Use cases

Practice DJ transitions

Load two tracks and practice beatmatching, crossfader cuts, and smooth transitions without needing physical DJ hardware. Use the BPM detection feature to align tempos and the EQ to create clean frequency swaps between songs during transitions.

Create seamless workout playlists

Loop high-energy sections of your favorite tracks and crossfade between them to build a continuous workout mix. Set A-B loop markers on the best drops and choruses, then export the entire session as a single WAV file for your gym playlist.

Remix YouTube music for content creation

Paste YouTube URLs to load royalty-free music or creative commons tracks directly into the decks. Blend multiple sources together, adjust EQ and speed, then export a unique background mix for your podcast, stream, or video project.

Frequently Asked Questions

?What audio formats can I load?

You can load MP3, WAV, OGG, and FLAC files from your device. You can also paste YouTube URLs to load audio directly into either deck.

?How does the A-B loop work?

Click Loop A to set the start point and Loop B to set the end point. The track will continuously repeat between those two markers until you disable the loop.

?Can I adjust the speed of each deck independently?

Yes. Each deck has its own speed control that lets you slow down or speed up playback independently, which is essential for beatmatching two tracks.

?What is BPM detection?

The tool automatically analyzes each loaded track and estimates its beats per minute. This helps you match the tempos of both decks for smoother transitions.

?Is my data private?

Yes. All audio processing happens locally in your browser. Your files and YouTube URLs are never uploaded to any external server.

?Is this tool free?

Completely free with no limits, no watermarks, and no sign-up required. Use it as many times as you want.

?What format does the export use?

The mix is exported as an uncompressed WAV file, which preserves full audio quality. You can convert it to MP3 afterwards if you need a smaller file.

?Can I set multiple cue points per deck?

Yes. You can place several cue points on each deck to mark drops, breakdowns, or vocal entries. Right-click a cue point to remove it.
