YouTube Mixing Desk

Description

The YouTube Mixing Desk is a free web app for mixing music like a DJ, right in your browser, with no installation or sign-up. Two decks, A and B, each play a YouTube playlist, and the crossfader moves from one to the other, by hand or automatically. It works well for parties, events, radio shows or shops.

Features

• Two independent decks: YouTube playlists, single YouTube videos, .mp3 / .mp4 files from your device, .m3u playlists and direct links.
• Crossfader and a smooth A → B mix button, from 2 to 20 seconds.
• Auto mix: the next deck starts on its own 5 to 60 seconds before the end of the track.
• Pitch from −50% to +50% on A, B or both, with the actual BPM displayed.
• BPM entered by hand or measured with TAP, remembered for each track.
• Effects: fade in, fade out, kill and chopper.
• Three transition mini players for your jingles, triggered by holding a button.
• Editable lists: move tracks, remove them with undo.
• Unavailable tracks are skipped automatically so the music never stops.

On a computer

• The three columns sit side by side: deck A, pitch and transitions, deck B.
• Keys 1, 2 and 3 on the keyboard trigger the jingles.
• Drag your audio and video files straight onto a deck, and reorder tracks with the mouse, even from one deck to the other.

On a phone or tablet

• In landscape mode, the compact layout keeps the three columns side by side. In portrait mode, everything stacks.
• Touch controls: keep your finger on a transition button to play the jingle.
• The “Files” button opens the music stored on your device.
• Tap “Play” once to allow sound: mobile browsers block autoplay.

User guide

1. Load music. On first launch, a playlist is already loaded. To change it, paste a YouTube playlist link into a deck’s field, then press “Load”. To add a single track, paste its link, then choose “Add” (end of the list) or “Play next”.
2. Add your files. The “Files” button adds .mp3, .mp4 and other audio or video files. For an .m3u playlist, select it together with its audio files.
3. Start playback. “Play” starts the deck. Tapping a track in the list plays it right away, and ⏮ ⏭ change tracks. The countdown shows the time remaining.
4. Mix. Move the crossfader toward A or B, or press “Mix A → B” for a smooth change over the chosen “Duration”. With “Auto mix” ON, the next deck takes over at the time set in “Before end”.
5. Match the tempo. Enter the track BPM or press “TAP” to the beat. Pitch speeds up or slows down deck A, deck B or both (A+B), and the “0” button resets it.
6. Add effects. “Fade in” and “Fade out” last as long as the “Duration” setting. “Kill” cuts the sound and “Chopper” chops it rhythmically: press again to stop them.
7. Play jingles. Paste a YouTube link into a transition mini player, set the “Start” in seconds, then hold the button, or key 1, 2 or 3: the jingle plays as long as you hold it.
8. Organize the lists. On a computer, drag a track to move it, even to the other deck. The ✕ removes a track and “Undo” brings it back. A crossed-out track is unavailable: it is skipped automatically.
9. Show the real titles (optional). A YouTube API key, entered under “YouTube API key”, shows the exact track titles. It stays saved in your browser.

Good to know: your playlists, BPM and jingles are saved in this browser. Files from your device need to be added again after the page reloads.
