WhatChord is an interactive chord identification, key detection, and harmony exploration app. Identify voicings from live Bluetooth or USB MIDI input or manual note entry, follow the key as you play, then explore chords, scales, keyboard patterns, and harmonic context. It is optimized for speed, accuracy, and musician-expected naming, favoring stable, conventional interpretations over simple note-matching.
Tonbandfetzen is a collection of command-line tools that allow you to compose music based on audio fragments generated from plain text input. It contains:
iamf-tools implements tools to help users process and work with the IAMF format. These tools can be used as a complement to the libiamfreference decoder and other tools such as ffmpeg and MP4Box.
AudioTube can search YouTube Music, list albums and artists, play automatically generated playlists, albums and allows to put your own playlist together. It is adapted to mobile phones and desktop computers.
Bitfake was originally created to detect fake .FLAC files through spectral analysis. It has since grown into a multipurpose CLI tool for handling music more easily and efficiently.
One common problem was that getting a track’s metadata required long ffprobe commands with messy output. Converting music with ffmpeg was also repetitive. The command itself is easy to remember, but writing scripts to convert entire directories felt inefficient and slow. This project now performs metadata and conversion tasks directly through linked libraries (TagLib/libsndfile/libav*).
Features:
Get metadata
Get ReplayGain info (useful for music players)
Spectral analysis on 44.1 kHz .FLAC files (higher sample rates may be misrepresented, so be careful)
Lossy diagnosis (banding score)
File Conversion + VBR Support (Works for outputs like .wav, .flac, .ogg, .mp3, .aac, .opus)
Tagging metadata (Works for single files, but not directories yet)
Calculating ReplayGain and applying it to files (Works for track replay gain iterating through directories, album replay gain is a bit funky?)
Directory Conversion (works for all previously mentioned formats!)
CoverArt+ (Brings along cover art among all conversions!)
Organizing Files by album! (Give a dir of random music, and bitfake will organize it – ty to uncognic)
Directory Tagging (YAY!)
Album folder renaming from tags (Artist – Album (Year))
Gnomoradio is a program that can find, fetch, share, and play music that is freely available for file sharing.

It runs on GNU/Linux and other UNIX-compatible systems, but it is no longer actively developed or maintained.
cplayer is a small, statically served, client-side album-based audio player for modern web browsers. You simply drop a build into a directory on your web server, create a manifest.json file that describes the album metadata and track URIs and you’re done.
