Open Source ActionScript Multimedia Software

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.

This editor is a free and open-source online tool which lets you design html pages with an interface very close to dreamweaver's or powerpoint's one.

Alternativa3D is a high-tech, open-source 3D engine built for ActionScript 3 and Adobe AIR, offering GPU-accelerated performance for browser-based games and applications, with a focus on high performance and resource efficiency. Alternativa3D is a high-tech and high-performance 3D engine for ActionScript 3 and Adobe AIR. It supports hardware acceleration for browser-based games and applications. Initially, the engine was designed to meet our own needs but we realized that it wouldn't be fair to limit the use of the technology to just one game. That is why we decided to make it an open source engine. Since our top priorities are high performance and resource efficiency, we recommend using it for games with high-resolution graphics.

DragonBonesAS is a skeletal animation framework for ActionScript 3 and Flash, designed to simplify the implementation of complex 2D animations. It separates the animation data from display logic, allowing developers to reuse assets, blend animations, and reduce draw calls. DragonBones supports the creation of character rigs, timelines, and inverse kinematics, making it popular in Flash-based game development.

Standing Wave 3 is an ActionScript 3 audio library that provides high-level control over the Flash Player’s SampleDataEvent API for streaming audio output. It builds on the foundation of Standing Wave 2 but has been extensively refactored, with its core sample storage and manipulation routines rewritten using Adobe Alchemy for significant performance improvements. Originally derived from the audio engine used in the Noteflight Score Editor, the library allows developers to combine and chain together audio sources, filters, and sequences to create dynamic, real-time sound experiences. Supported audio sources include MP3s, WAV files, and algorithmic generators, while filters enable effects such as echo, equalization, and envelope shaping. The system is flexible enough to handle complex timing sequences of audio, making it suitable for advanced audio applications or interactive projects.

SoundAS is a modern and lightweight sound management library for ActionScript 3, built for both Flash and Adobe AIR applications. Its primary purpose is to simplify audio playback, making it easier to transition between sounds, manage sound effects separately from looping music, and handle complex sound interactions. The library provides a clean API that supports chaining, allowing concise and expressive sound control in just a few lines of code. It includes built-in support for seamless looping, volume fading, tweening, and grouping of sounds, making it highly useful for game development and multimedia projects. SoundAS also offers a modular structure, enabling developers to use individual SoundInstance objects directly without needing the full system. With a permissive license and active examples, it is designed to be straightforward, flexible, and powerful for managing audio in ActionScript projects.
