Allows you to edit metadata of FLAC files. CO
This script should not be not be installed directly. It is a library for other scripts to include with the meta directive // @require https://update.greasyfork.org/scripts/40545/646530/JS%20FLACMetadataEditor.js
Script allows you to edit metadata in FLAC files
inspired by egoroof's Browser ID3 Writer
// # 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);
May be accessed through editor.metadata
Do console.log(editor) to explore it. Structures have self-descriptive names
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;
CUESHEET instead. And honestly, even metaflac cannot embed all of my .cue into flacs. Nevermind)
