About synced+

synced+ is a web-based tool for creating word-timed enhanced lyrics (ELRC files). The user loads an audio track in the browser, imports a lyric file or pastes lyrics from the clipboard, and sets each line or word timestamp to the current playback position. Finished lyrics can be exported in a selected format.

The homepage states that all processing is done locally, that no audio or text is sent to a server, and that data is stored in the browser's localStorage. Pricing is not stated. No public repository is listed, and the directory marks the project as not open source.

Key features

  • Imports audio and fills track name, artist, and album fields from file metadata when present
  • Imports a lyric file or pastes lyrics from the clipboard
  • Sets line or word timestamps to the current playback time with a button

synced+ FAQ

Is my audio or lyric text uploaded to a server?
The homepage's privacy notice says all processing is done locally and no audio or text gets sent to a server. Data is stored in client localStorage.
How do I sync individual words?
Click the Expand button to show the word container. Set a time for a word using the timestamp button, and clicking that word later jumps audio playback to its time.
Is something wrong or out of date?
