Build a mix
- Paste a YouTube or YouTube Music link (a single song or a playlist) into the box above the playlist, or press Ctrl/⌘+V anywhere on the page. You can also add your own files (MP3, WAV, M4A, FLAC) with Add music or by dropping them on the page. Tracks play in order, top to bottom.
- On the timeline, drag a song's green edge to set where it starts and its red edge to set where it ends. Drag the ◆ to set how long it crossfades into the next song.
- For exact timing, use the Track editor. Type times like 1:23.40, nudge them 0.05 s at a time (hold Shift for 1 s), or click the waveform to preview from that point.
- Press Auto mix to play the whole set. Mix now starts the crossfade early, and Cut jumps to the next song straight away. Either one saves the new end point to the song.
- Use Export WAV to render the finished mix to a file, or Rec to capture a live performance with your EQ and fader moves.

Your files stay on this device. Nothing is uploaded. Each song's IN, OUT and fade settings are saved in this browser, so they come back when you add the same file or video again.
YouTube tracks
YouTube plays inside its own player, so the app controls its volume for fades and crossfades, but EQ, filter, tempo, waveforms and BPM aren’t available, and YouTube audio can’t be exported or recorded. Some videos are blocked from playing outside YouTube by their owners. On iPhone and iPad, iOS doesn’t let websites change YouTube’s volume, so fades there turn into cuts. Use a computer or Android for smooth YouTube mixes.
