FLACMetadataEditor

Script allows you to edit metadata in FLAC files

inspired by egoroof's Browser ID3 Writer

Live demo

Usage:

// # Creating editor instance:
const editor = new FLACMetadataEditor(ArrayBuffer);

// # Get version:
const editorVersion = editor.scriptVersion; // <- e.g. '0.0.2.1'

// # Editing tags:
// List with standard field names: https://xiph.org/vorbis/doc/v-comment
editor.addComment('ARTIST=Laibach');
editor.addComment('ARTIST', 'Laibach');

// All properties are facultative except "data"
// Default values (except "data", of course) presented in example:
editor.addPicture({
    APICtype: 3,
    MIMEType: 'image/jpeg',
    colorDepth: 0,
    colorNumber: 0,
    data: ImageDataAsArrayBuffer,
    description: '',
    width: 0,
    height: 0
});

// remove single atrist
editor.removeComment('ARTIST', 'Laibach');
// remove all atrists
editor.removeComment('ARTIST');
// remove ALL comments
editor.removeComment();

// # Writing changes
editor.serializeMetadata();

// # Convert result to blob
const resultArrayBuffer = editor.arrayBuffer;
const blob = new Blob([resultArrayBuffer], {type: 'audio/flac'});
const url = URL.createObjectURL(blob);

What else?

Editable full FLAC metadata except CUESHEET

May be accessed through editor.metadata

Do console.log(editor) to explore it. Structures have self-descriptive names

Chains

As all public functions return this, we are able to create trains. e.g. this returns changed ArrayBuffer with only one comment — TITLE=The Whistleblowers

new FLACMetadataEditor(ArrayBuffer).removeComment().addComment('TITLE','The Whistleblowers').serializeMetadata().arrayBuffer;

TODO:

  • More debug output
  • METADATA_BLOCK_CUESHEET parsing (most forums don't recommend use it. Use tag CUESHEET instead. And honestly, even metaflac cannot embed all of my .cue into flacs. Nevermind)
