Open Source ActionScript Sound/Audio Software

Version 3.x available here on SourceForge has been superseded by version 4.x available on Github. The later is a port to JavaScript, PHP and Ruby - all dependencies on Flash have been removed, as well as some of the functionality it provided. Version 3.x --------------- Extensible Flash and PHP online video editor with effects, transitions, titling, timeshifting and compositing. Client side ActionScript provides a robust GUI that interacts with PHP through simple XML protocols for saving edit decision lists, handling uploads and asset searching. XML is also used to describe the GUI itself as well as its underlying functionality - there is no need to recompile the Flash applets! But if you so desire then custom fonts, effects and widget classes can be written in AS3 - PixelBender support too, for effects and transitions. http://www.moviemasher.com

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.

FlashWavRecorder is a Flash-based tool that enables recording audio from a user's microphone and exporting it as a WAV file in real time. It uses Flash Player to access audio input and communicate with JavaScript to control recording sessions from the browser. This was especially useful before native browser audio APIs became widely supported and remains relevant in legacy systems requiring Flash-based audio capture.

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.

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.
