CDPlayer ~ CD Player App
CDPlayer is a Java desktop app that recreates the tactile feel of a physical CD player for local audio playback. Load a track, press play, and enjoy a simple, distraction-free music experience without relying on a browser or web app — no accounts, no streaming, no internet required to play a song. Built with plain Java and native Swing/AWT — no external UI framework, single self-contained app
Plays local audio files through a custom low-latency streaming engine, with FFmpeg handling the formats Java can’t decode natively
Full queue management: drag-and-drop, drag-to-reorder, shuffle, repeat, crossfade, volume, mono downmix, and per-track removal — queue is saved automatically and restored next launch
Ten built-in themes — nine animated ones plus AUTO, which derives its whole palette from the current track’s own album art
A sleep timer that pauses playback after a set time, with a live countdown in the header
A 10-band graphic equalizer with built-in and savable custom presets, and a beat-synced visualizer
True fullscreen, a distraction-free fullscreen Visualizer Mode, and a Mini Mode that shrinks the whole app down to a small always-on-top widget
A dedicated Settings dialog for theme, crossfade, mono, and an ambient blurred-cover-art background wash
Automatic metadata and album art, with an online lookup fallback when a file has none
Works on Windows, macOS, and Linux. ffmpeg required.

mp3-packer ~ Bitrate Reduction Script
I have more music than would fit onto the memory card of my phone. This is largely due to the 256 kBit/s versions that are sold now. On the phone, I do not really hear the difference between 256 kBit/s and 128 kBit/s, but I can clearly see the difference in size.
This script creates a whole copy of your music library, just with a smaller bitrate. It uses either ffmpeg or lame to convert the tracks.

Carat ~ Concise Atmos Ripping Automation Tool
Carat is a lightweight, automated GUI utility designed to accept Dolby Atmos music releases in practically any format, locate the primary title in the release, retrieve metadata and cover art from the internet, and incorporate the release directly into your digital music library in a single click.
From the moment a new Blu-ray arrives in your mailbox, Carat handles the entire pipeline—extraction, processing, metadata acquisition, and cover art—with zero friction. If your source files are already on your SSD, Carat will process an entire release in a minute or two (depending on the speed of your computer). If you are starting from a physical disc, the time is limited by the read speed of your optical drive (expect five to ten minutes).

Dynamic Audio Normalizer ~ Advanced Normalization
Dynamic Audio Normalizer is a library for advanced audio normalization purposes. It applies a certain amount of gain to the input audio in order to bring its peak magnitude to a target level (e.g. 0 dBFS). However, in contrast to more “simple” normalization algorithms, the Dynamic Audio Normalizer dynamically re-adjusts the gain factor to the input audio. This allows for applying extra gain to the “quiet” sections of the audio while avoiding distortions or clipping the “loud” sections. In other words: The Dynamic Audio Normalizer will “even out” the volume of quiet and loud sections, in the sense that the volume of each section is brought to the same target level. Note, however, that the Dynamic Audio Normalizer achieves this goal without applying “dynamic range compressing”. It will retain 100% of the dynamic range within each “local” region of the audio file.
The Dynamic Audio Normalizer is available as a small standalone command-line utility and also as an effect in the SoX audio processor as well as in the FFmpeg audio/video converter. Furthermore, it can be integrated into your favorite DAW (digital audio workstation), as a VST plug-in, or into your favorite media player, as a Winamp plug-in. Last but not least, the “core” library can be integrated into custom applications easily, thanks to a straightforward API (application programming interface).

Lattice ~ CLI Toolkit For Music Collectors
A high-performance CLI toolkit for music collectors who manage their own libraries. Lattice provides a suite of tools for library visualization, integrity verification, cover art extraction, and metadata auditing — all from a single, zero-dependency script.
Why this exists
Modern music players often hide your library behind proprietary databases. Lattice is built for collectors who treat the filesystem as the source of truth. It reads tags directly via mutagen, ensuring your library is portable and player-agnostic.
Features:
| Mode | Flag | Description |
|---|---|---|
| Library Tree | --library | Generate a formatted ASCII/Unicode tree of your entire collection. |
| AI Library | --ai-library | Token-efficient export designed for LLM recommendation prompts. |
| Genre Wings | --all-wings | Generate separate library catalogs segmented by genre. |
| Integrity Checks | --testFLAC | Parallel verification of FLAC/MP3/Opus/WAV integrity via FFmpeg. |
| Art Extraction | --extractArt | Extract embedded covers with format-priority ranking (FLAC > Opus). |
| Tag Audit | --auditTags | Identify and report files with missing or inconsistent metadata. |

Bitfake2 ~ Audio Tool Handler & Manipulator
Bitfake was originally created to detect fake
.FLACfiles 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
ffprobecommands with messy output. Converting music withffmpegwas 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
.FLACfiles (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))
- Spectrogram generation (in .png)
- Version info (WOW! BEST YET!)
- MusicBrainz Syncing data.
