SOURCE & RECORD

SOURCE
No signal
RECORD

▲ Record grabs whatever is on screen, with audio. Render full video restarts your track and stops by itself at the end.

PRESETS

LOOK
AUTO-DRIFT

▲ Auto-drift moves through the presets on a strong beat, every 10, 20 or 30 seconds.

FINE TUNING

▲ Every slider is limited to a range that looks good, so you can't break it. Go wild.

TITLE CARD

STYLE

▲ The title card is burned into your recording. Loading a file fills in the title for you.

HOW TO USE

  1. 01

    PICK A SOURCE

    LOAD TRACK plays an MP3 or WAV from your computer. You can also drag a file onto the page.

    MIC / LINE IN listens to your mic or audio interface. Great for live sets.

    CAPTURE TAB reacts to another browser tab (SoundCloud, YouTube, your DAW's web player). Tick "Share tab audio" when Chrome asks.

  2. 02

    MAKE IT YOURS

    Start with a PRESET, then change the MODE, COLOUR and MIRROR. Turn on AUTO-DRIFT and it moves through the presets on the beat.

    Pick a FRAME for where you're posting: 9:16 for Reels, TikTok and Shorts; 1:1 or 4:5 for the feed; 16:9 for YouTube.

  3. 03

    RECORD IT

    RECORD saves a video of the screen with the audio. Press it again to stop, and the file downloads.

    RENDER FULL VIDEO restarts your track in 16:9 with auto-drift on, and stops by itself when the song ends.

GOOD TO KNOW

  • Keep this tab visible while recording. Browsers slow down hidden tabs, and the video will stutter.
  • Depending on your browser you get an MP4 or a WebM. YouTube takes both. For Instagram or TikTok, convert a WebM to MP4 first (HandBrake is free).
  • Tab capture works in Chrome and Edge on a computer. On phones, use a track file or the mic.
  • Everything runs in your browser. Your audio never leaves your computer.
  • Only post music you have the rights to.

NOT MOVING?

  • Watch the level meter. If it's flat, no audio is reaching the page.
  • Mic blocked? Click the icon in the address bar, allow the microphone, and try again.
  • Tab capture silent? Share a tab (not a window) and tick "Share tab audio".
