Managing large collections of audio files can get surprisingly tedious.

Sometimes you just want to:

• convert a whole folder of WAV files to MP3,
• edit album and track metadata in one place,
• add or replace artwork,
• and finish everything without jumping between multiple tools.

That is exactly why I built AlbumMP3Maker.

It is a free Windows desktop application designed for fast batch audio conversion and metadata editing.

The app is currently being prepared for release on the Microsoft Store.

What is AlbumMP3Maker?

AlbumMP3Maker is built around a simple workflow:

Drop audio files → edit metadata → choose artwork → convert to MP3

You can drag and drop individual files or entire folders, edit album information, and process multiple tracks as one album.

The goal is to keep the workflow fast and straightforward.

Batch MP3 Conversion

AlbumMP3Maker can convert the following formats to MP3:

• WAV
• M4A
• M4P (DRM-free)
• FLAC
• AIFF
• AIF

Available MP3 bitrates are:

128 / 192 / 256 / 320 kbps

The default setting is 320 kbps.

Metadata Editing Without Re-encoding

AlbumMP3Maker also includes an Edit Tags Only mode.

Supported formats include:

• MP3
• WAV
• M4A
• M4P (DRM-free)
• FLAC
• AIFF
• AIF

In this mode, the original audio data is not re-encoded.

Only metadata and artwork are updated.

You can edit fields such as:

• Title
• Artist
• Album
• Album Artist
• Track Number
• Year
• Genre
• Artwork

Artwork Support

AlbumMP3Maker supports:

• JPEG
• PNG
• WebP

Existing embedded artwork can be detected and displayed automatically.

You can also replace artwork or remove it completely.

MusicBrainz and Cover Art Archive Integration

Album information can also be retrieved online.

AlbumMP3Maker can search MusicBrainz for metadata and retrieve cover artwork from the Cover Art Archive.

This makes it much faster to organize albums without entering every field manually.

The online lookup feature is optional, and the core application can still be used locally without it.

English, Japanese and Traditional Chinese

The interface currently supports three languages:

• English
• 日本語
• 繁體中文（台灣）

English is the default language.

The selected language is saved automatically and restored the next time the application is launched.

Free and Ad-Free

AlbumMP3Maker will be released completely free of charge.

There are no ads and no user tracking.

I briefly considered an ad-supported version, but for a desktop utility like this, I prefer keeping the interface clean and focused on the actual work.

AlbumMP3Maker is released under the GNU General Public License v3.

A Custom FFmpeg Build

Audio conversion is handled by FFmpeg.

For the release version, I decided not to ship a large general-purpose FFmpeg build.

Instead, I built a minimal FFmpeg 8.1 configuration containing only the components AlbumMP3Maker actually needs.

MP3 encoding is handled by LAME 3.100.

This also reduced unnecessary dependencies and made the final distribution cleaner.

Microsoft Store Release

The Windows version is being prepared for distribution through the Microsoft Store.

The Store release will use the MSIX packaging format, allowing AlbumMP3Maker to be installed like a regular Windows application.

A macOS version is also planned for the future.
