MP3val ~ Validate Your mp3s


MP3val is a small, high-speed, free software tool for checking MPEG audio files’ integrity. It can be useful for finding corrupted files (e.g. incompletely downloaded, truncated, containing garbage). MP3val is also able to fix most of the problems. Being a multi-platform application, MP3val can be run both under Windows and under Linux (or BSD).

The most common MPEG audio file type is MPEG 1 Layer III (mp3), but MP3val supports also other MPEG versions and layers. The tool is also aware of the most common types of tags (ID3v1, ID3v2, APEv2).

FlacSquisher ~ Lossless to Lossy Conversion


FlacSquisher converts a library of FLAC files to MP3, Opus, or Ogg Vorbis format, maintaining the directory structure in the original library. That way, you can maintain your FLAC files for home listening, and easily convert them to MP3, Opus, or Ogg format for mobile use, where storage space is more often tightly constrained.

Features:

  • Converts to MP3 or Ogg Vorbis
  • Maintains directory structure from original library
  • Takes advantage of multicore processors
  • Can copy or ignore files by extension (album art, log files)
  • Ignores files already encoded previously
  • Compatible with Mono on Linux

NAudio ~ .NET Audio & MIDI Library


NAudio is an open source .NET audio and MIDI library, containing dozens of useful audio related classes intended to speed development of audio related utilities in .NET. It has been in development since 2002 and has grown to include a wide variety of features. While some parts of the library are relatively new and incomplete, the more mature features have undergone extensive testing and can be quickly used to add audio capabilities to an existing .NET application. NAudio can be quickly added to your .NET application using NuGet.

beets ~ The Music Geek’s Media Organizer


The purpose of beets is to get your music collection right once and for all. It catalogs your collection, automatically improving its metadata as it goes using the MusicBrainz database. Then it provides a bouquet of tools for manipulating and accessing your music.

Because beets is designed as a library, it can do almost anything you can imagine for your music collection. Via plugins, beets becomes a panacea:

  • Fetch or calculate all the metadata you could possibly need: album art, lyrics, genres, tempos, ReplayGain levels, or acoustic fingerprints.
  • Get metadata from MusicBrainz, Discogs or Beatport. Or guess metadata using songs’ filenames or their acoustic fingerprints.
  • Transcode audio to any format you like.
  • Check your library for duplicate tracks and albums or for albums that are missing tracks
  • Browse your music library graphically through a Web browser and play it in any browser that supports HTML5 Audio and lots more.

YAFS ~ Changing Song Order On USB Sticks

YAFS is a multi-platform, open source, freeware, command line utility with a GUI (Graphical User Interface).

Ex Falso/Quod Libet ~ Cross Platform Music Editor / Library / Player


Quod Libet

Quod Libet is a GTK+-based audio player written in Python, using the Mutagen tagging library. It’s designed around the idea that you know how to organize your music better than we do. It lets you make playlists based on regular expressions (don’t worry, regular searches work too). It lets you display and edit any tags you want in the file, for all the file formats it supports.

Unlike some, Quod Libet will scale to libraries with tens of thousands of songs. It also supports most of the features you’d expect from a modern media player: Unicode support, advanced tag editing, ReplayGain, podcasts & Internet radio, album art support and all major audio formats – see the screenshots.

Ex Falso is a program that uses the same tag editing backend as Quod Libet, but isn’t connected to an audio player. If you’re perfectly happy with your favorite player and just want something that can handle tagging, Ex Falso is for you.

freedb.org ~ Metadata Lookup Service


Sadly, this service was terminated as of March 2020, apparently due to corporate indifference.

freedb was a free CD and music database service to look up textual metadata about music, audio or data CDs. This was done by a client which queried the freedb database. As a result, the client displayed the artist, CD title, track list and some additional information. Clients are for example CD players, CD rippers and CD burning software.
