A set of utilities for working with Byzantine sheet music.
PsalticTools includes:
• a set of utilities (plugins) for typing of Byzantine notes in parallel double notation (Byzantine and Western), based on MuseScore free music editor;
• the PsalticHelper program for searching for formulas of Byzantine music in music books.
• the UniPsaltica2 font with the characters of the musical Byzantine notation in Unicode.

GrooveKraft is a fast, lightweight music collection manager that uses Discogs and MusicBrainz to enrich your collection with detailed metadata and artwork.

Autometa is a minimalist, customizable JScript Panel script designed to quickly create autoplaylists based on the current track’s tags with a single click (similar to the quick search function).

QMidiArp is a MIDI arpeggiator, phrase generator and controller LFO for ALSA and JACK. It can run multiple synchronized arpeggiators, LFOs and step sequencers. The modules are also available as LV2 plugins with Qt user interface. QMidiArp has been growing since June 2009 on top of Matthias Nagorni’s original arp idea.
Features:
- Programmable arpeggio patterns, LFO waveforms and sequences
- Modular setup of arpeggiators, MIDI LFOs and step sequencers
- MIDI-controllable (MIDI-Learn)
- Synchronization with MIDI Clock or JACK Transport possible
- Optional triggering by keyboard or continuous play mode for all modules
- Patterns can be stored and switched by MIDI control while running
- JACK MIDI or ALSA MIDI backends
- Modules available as LV2 Plugins

This is a helper application that uploads images to Catbox, and is meant to be invoked by the foo_discord_rich plugin. With a fork of the Discord Rich Presence Integration component, uploads cover art to catbox.moe and prints the URL.
The Sound Description Interchange Format (SDIF) is an established standard for the interchange of sound descriptions and analysis data. This project provides libraries, SDIF (in C) and Easdif (in C++), tools, and wrappers to read and write SDIF files.

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.
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.
| 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. |
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*).

RxFFmpeg is a high-performance multimedia processing framework built on top of FFmpeg and optimized specifically for Android environments, enabling developers to perform complex audio and video editing operations programmatically. It integrates widely used encoding libraries such as x264, mp3lame, and fdk-aac, allowing it to support a broad range of media formats and transformations. The framework provides a wrapper around FFmpeg commands, making it easier to execute advanced media operations without directly handling low-level command syntax. It supports both synchronous and asynchronous execution, enabling developers to manage long-running media tasks efficiently within mobile applications. The system also includes features like hardware acceleration through MediaCodec, significantly improving performance on supported devices. Its design focuses on flexibility, allowing users to perform tasks such as transcoding, clipping, filtering, and compositing media with minimal overhead.
