The bfxr project by increpare is a sound-effects generator tool originally built using Flash + AIR, based on the earlier Sfxr project. Its purpose is to enable users, especially game developers and sound designers, to quickly generate retro, 8-bit/“chiptune” style sound effects (“bleeps”, “booms”, “zaps”, etc.) without deep knowledge of audio signal processing. It offers an interactive GUI through which you can tweak many parameters (oscillators, envelopes, filters, etc.) to sculpt custom sound effects; you can preview in real time, export, and iterate. The project includes libraries, HTML templates, and both ActionScript and JavaScript code. It has been well-received (over a thousand stars), but as of 2025, it has been superseded by a newer version called bfxr2, which is a JavaScript reworking of the original.

"Le chansonnier" is a program allowing to create, manage, display and publish a guitar songbook. It is able to produce nice PDF documents containing song and chords along with chord diagrams.

LiveAvatar is an open-source research and implementation project that provides a unified framework for real-time, streaming, interactive avatar video generation driven by audio and other control signals. It implements techniques from state-of-the-art diffusion-based avatar modeling to support infinite-length continuous video generation with low latency, enabling interactive AI avatars that maintain continuity and realism over extended sessions. The project co-designs algorithms and system optimizations, such as block-wise autoregressive processing and fast sampling strategies, to deliver real-time frame rates (e.g., ~45 FPS on appropriate GPU clusters) while handling non-stop generation without quality degradation. LiveAvatar focuses on delivering not just high-quality visuals but also the responsiveness necessary for immersive conversational experiences, making it suitable for advanced AI agents, virtual assistants, and interactive streaming contexts.

Volocian believes first and foremost that financial status shouldn’t be a barrier to entry in multimedia content creation. Whether you want to design a product or website, record a band, remix a song, or produce a feature length movie with professional post production graphics and effects, Volocian™ wants to help, even if you’re using borrowed hardware with no previous experience. We provide affordable products and services for any budget, including cost-free solutions for education and demo purposes, while everything we do is designed with ease of use and flexibility in mind, to suit everyone from novice hobbyists to expert professionals. Wherever possible, Volocian™ relies on free, open source, and cross-platform software to prevent vendor lock-in, planned obsolescence, and software as a service licensing. While we remain pragmatic about the use of proprietary software, as we’re aware of the feature limitations of some open source solutions, free solutions are preferred.

This project is a Java based total radio station automation package using the Java Sound Framework. Its uses range from running an internet streaming radio station to running a full FM or AM broadcast facility.

JAVIER is a JAvascript Voicexml InterpretER, designed (but not restricted) to run inside a web browser, its main engine has less than 1000 lines of code. It's maybe, the tiniest but (almost) FULL VoiceXML implementation.

A java/SWT application designed to control the Sonos ZonePlayers.

MIDITOR is a command line compiler that takes ASCII edited music which can be in the style of drum or guitar tablature but with accuracy. MIDITOR is comparable to a sequencer. It turns any ASCII editor into a MIDI editor, for loops, sequencing and composing. Any MIDI message can be sent at specific times including patch changes, control changes.... Tracks and channels can be easily rendered in parallel and the powerful macro preprocessor handles the repetitious nature of music writing. Music is easily scored in any editor chromatically and then output as a MIDI file to quickly check and play the score on FluidSynth or Timidity for instance. Conventional style guitar and drum tab can be used, even conventional style notation using macros, or just one line of chromatic notation.

MPD Controler and ogg stream player

A java based repository for MusicXML.

Providing a MIDI Player for animated visualization of musical structures.

NovaSR is an extremely lightweight and high-performance audio upsampling model that transforms low-quality 16 kHz audio into clearer, high-fidelity 48 kHz audio with remarkable speed and efficiency. At only about 50 KB in size, the model is orders of magnitude smaller than typical audio super-resolution networks, yet it achieves high quality and realtime performance thanks to its compact architecture and efficient convolutional design. NovaSR is especially valuable for post-processing tasks in speech enhancement, TTS pipelines, and dataset restoration where low sampling rates degrade perceived audio clarity; the minimal model size also makes it suitable for edge and embedded use cases where memory is at a premium. Its performance can reach thousands of times realtime on modern GPUs, allowing massive audio batches to be processed with negligible compute overhead.

OpenBroad is a streaming client/server system, minded for sharing music, interviews etc. among radiostations.

OpenDAFF is a free, open-source software package for directional audio data - like the directivity of microphones, speakers, as well as head-related transfer functions (HRTFs)

This project is abandoned. Download these files at your own risk. For the latest version please visit http://decafbad.net/projects/piddlepodder/ This application is a podcatching client written in Perl. It is based off of the simplicity of bashpodder with a few added features. It downloads podcasts from a list of XML feeds, and puts them into a download directory by date.
