Show HN: CLI for writing SYLT synced lyrics to MP3 files

A pretty convenient CLI tool that reads and writes synced lyrics to MP3 files in SYLT (SYnchronized Lyrics/Text) format.

• Supported input formats: LRC, SRT, and VTT
• Configurable language codes (ISO 639-2 format)
• Read and display existing SYLT lyrics from MP3 files
• Creates output files with " - sylt" suffix to preserve originals

Still, backing up originals is recommended.

Visit the Releases page for pre-compiled binaries.

You can also build from source:

Currently go-sylt supports ID3v2.3 and ID3v2.4 tags only. For MP3 files with older or unsupported ID3 versions, please convert them to a supported version first. You can use tools like Kid3 for this purpose.

The tool creates a new MP3 file with the same name as the input file but with " - sylt" appended before the extension. For example:

• Input: song.mp3 → Output: song - sylt.mp3

• github.com/bogem/id3v2/v2 - ID3v2 tag manipulation

Contributions are welcome! Should you find any issues or have any suggestions, kindly submit an issue or PR with the provided templates. Thank you!

• Go 1.21 or above
• golangci-lint for linting

Visit the Releases page, create a release on the main branch with a tag in the format of X.Y.Z or X.Y.Z-rc1. The workflow will automatically build and upload the binaries.
