Open Source Audio Editing Software

LosslessCut aims to be the ultimate cross platform FFmpeg GUI for extremely fast and lossless operations on video, audio, subtitle and other related media files. The main feature is lossless trimming and cutting of video and audio files, which is great for saving space by rough-cutting your large video files taken from a video camera, GoPro, drone, etc. It lets you quickly extract the good parts from your videos and discard many gigabytes of data without doing a slow re-encode and thereby losing quality. Or you can add a music or subtitle track to your video without needing to encode. Everything is extremely fast because it does an almost direct data copy, fueled by the awesome FFmpeg which does all the grunt work. Lossless merge/concatenation of arbitrary files (with identical codecs parameters, e.g. from the same camera). Lossless stream editing: Combine arbitrary tracks from multiple files (ex. add music or subtitle track to a video file).

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.

Orchid Studio is a beautiful full multimedia operating system that can edit sound, video, and photographs on a 10 year old laptop with just 4GB of memory. Although designed for 10 year old and newer 64-bit computers that are unable to upgrade to windows 11, it excels on newer systems. It works great on multi-monitor and ultra wide screen monitor setups. Orchid Studio can be run live from a USB drive, however is intended to be installed on a solid state drive or hard drive. Orchid Studio is designed as a single user setup where the “admin” user does not require passwords for updates, installing software, and performing most administrative tasks. Other users will require passwords to be used for these functions. Passwords: root and admin initial passwords are “admin”, if you are security conscious you should change them.

DubEdit allows to edit the Video and the Audio channels of a media though the combination of layers that can be sources (video, picture, parametric shape, audio track, etc...), filters (resize, contrast, transparency, amplify, etc...) and mixers. All filters can be adjusted using parameters that may vary with the time in the media, either based on automatic curves between key frames or driven by formulas like in a spreadsheet. Ergonomic interface (including performance) is an important driver in designing DubEdit: every operation is undoable, all video editing is WYSIWYG. At this time DubEdit has only basic filters and mixers. But it has been designed to be easily extended with new powerful filters and mixers so that it can becomes capable of virtually any possible editing. Only DubEdit Libraries are available on SourceForge. You will find the DubEdit Program on http://dubedit.free.fr/Download (it does not match SourceForge OpenSource requirements)

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
