Overview

The Batch Audio Metadata Editor allows you to quickly update metadata tags across multiple audio files simultaneously. Easily modify fields like artist, album, genre, year, track number, and comments, or apply sequential track numbering, while keeping your original audio format or converting to MP3, WAV, FLAC, AAC, M4A, or OGG.

When to Use

  • •When you need to clean up inconsistent artist or album tags across an entire music album or podcast series.
  • •When preparing a batch of voice recordings or sound effects for distribution with standardized comments and genre tags.
  • •When you want to apply sequential track numbers to a set of audio files while converting them to a uniform format like MP3 or FLAC.

How It Works

  • •Upload up to 20 audio files in formats like MP3, WAV, FLAC, AAC, M4A, or OGG.
  • •Enter the new metadata values for artist, album, title, genre, year, track, or comments, and choose whether to apply sequential track numbering.
  • •Select your preferred output format (or keep the original format) and click the process button to download the updated audio files.

Use Cases

Standardizing album names and artist tags for a newly recorded music EP before uploading to streaming platforms.
Adding release years and custom comments to a batch of podcast episodes for archiving.
Converting raw WAV sound effects to MP3 while tagging them with a specific genre and sequential track numbers.

Examples

1. Standardizing a Music Album Release

Independent Musician
Background
An indie artist has finished recording an 8-track EP. The exported WAV files have messy filenames and missing metadata tags, making them look unprofessional.
Problem
The artist needs to quickly apply the same artist name, album title, release year, and genre to all 8 tracks, and assign sequential track numbers.
How to Use
Upload the 8 WAV files, enter the artist name and album title, set the genre to 'Indie Rock', choose the 'Sequential' track numbering option, and set the output format to FLAC.
Example Config
Artist: 'The Echoes', Album: 'Midnight Reverie', Genre: 'Indie Rock', Year: '2024', Track Numbering: 'sequential', Output Format: 'flac'
Outcome
All 8 files are updated with matching album metadata, numbered sequentially from 1 to 8, and converted to FLAC format.

2. Organizing Podcast Episodes for Archiving

Podcast Producer
Background
A producer has a batch of 15 MP3 podcast episodes from Season 2 that lack consistent metadata, making them hard to organize in media players.
Problem
The producer wants to batch-update the artist, album (season name), and add a copyright comment to all files without changing their MP3 format.
How to Use
Upload the 15 MP3 files, input the podcast name as the artist, 'Season 2' as the album, add a copyright notice in the comment field, and select 'Keep Original Format'.
Example Config
Artist: 'Tech Talk Daily', Album: 'Season 2', Comment: 'Copyright 2024 Tech Talk Media', Output Format: 'keep'
Outcome
All 15 podcast episodes are updated with the correct show details and copyright comments while remaining in their original MP3 format.
