Good to know
Made for the web
No YouTube API key is needed. The first playback must follow a tap because browsers block unsolicited audio. Distance is lightweight attenuation, so DualTube still uses exactly two YouTube players.
Online video and audio workspace
A two-video YouTube mixer built for live control.
DualTube combines two embeddable YouTube videos or playlists in one responsive workspace. Use it for comparisons, ambient layers, dance practice, DJ-style transitions, synchronized playlists, or creative video mashups without downloading source media.
Mix on any screen
Independent deck trims, a master level, equal-power crossfading, looping, playlists, and compact video controls work on desktop, tablet, and mobile.
Record every slider move
Signed-in users can capture crossfader, master, deck volume, and distance-depth input against both YouTube playback positions.
Share without a login wall
Creators sign in to save. Anyone with a public mix link can load and play its setup or automation without creating an account.
How to mix two YouTube videos
- Paste a YouTube video, Shorts, live, or playlist URL into each deck.
- Load both sources and select Play both.
- Move the crossfader and deck sliders to shape the mix.
- Sign in to record automation or create a permanent public share link.
Frequently asked questions
Does DualTube download or rehost YouTube videos?
No. Playback stays inside the official YouTube IFrame Player. The app stores only mixer settings, source URLs, and automation points.
Do viewers need an account to open a shared mix?
No. Authentication is required to create or save cloud data, but a public share link can be loaded and played anonymously.
Why does mobile audio behavior vary?
Mobile operating systems and YouTube control autoplay, background playback, advertisements, and per-player volume behavior.

Acceptable use
Use DualTube only with content you are permitted to access and in compliance with YouTube's Terms of Service, applicable law, and the rights of creators. Do not use the service to evade access controls, copy protected media, harass others, or distribute unlawful content.
Accounts and shared data
Firebase Authentication identifies account owners. Saved automation is private to its owner. A share link is intentionally public to anyone who has its unguessable URL; do not include sensitive information in share titles or descriptions.
Service availability
The service is provided as-is without warranties. YouTube controls playback availability, embedding, advertisements, and restrictions. Cloud data may be removed for abuse, security, or service maintenance.
Ownership
You retain rights to settings and automation you create. DualTube does not claim ownership of YouTube content and is not affiliated with or endorsed by YouTube or Google.
