Audacity 4 moves the whole interface onto Qt, replaces the tool modes with context aware clip editing, adds grouped clips and three workspaces, and stores projects in a new aup4 format. The 4.0.1 patch brought back export multiple and a portable Windows build.

After six quiet years LMMS shipped 1.3.0-alpha.2 in September 2026: 932 commits, 65 contributors and 8 new plugins, plus microtonal tuning, detachable windows and ARM64 builds. The stable release is still the one from July 2020.

Ardour 9.8 brings keys and scales into this open source digital audio workstation: notes outside the scale are marked in the piano roll and may be corrected per track. A crash during recording now recovers what was captured, losing at most five seconds.

Flameshot is an open source cross platform capture tool that lets you draw arrows, blur sensitive areas and drop text on the image right after the selection is made, with a rearranged toolbar, editable hotkeys and a command line interface for scripted captures.

From the ArtCraft team, an open source non linear video editor written from scratch in Rust: H.264, HEVC and ProRes codecs, the timeline, grading, audio and subtitles are all implemented in house.

OpenShot is the editing program you can hand to someone who has never cut a video: drag clips onto a timeline, drop a transition, add keyframes from a right click. Free, open source and without watermarks.

Traditional live streams arrive seconds behind reality, which is why the neighbour cheers before your phone shows the goal. Ant Media Server pushes WebRTC playback down to roughly half a second and covers ingest, transcoding and multi protocol delivery in one chain. Version 3.1 adds NDI sources, SRT with language tags and a new console.

Tautulli is an open-source dashboard that runs beside a home media server and turns viewing into numbers: who is watching, when, what, and on which device. Live cards show resolution, bitrate, bandwidth, subtitles and audio track, history is aggregated by user, content and hour, and notifications fire when content arrives or a playback fails. Version 2.18.1 arrived at the end of August 2026.

Kdenlive is the non-linear video editor built by the desktop community behind the K suite, running on Windows, macOS and Linux with the same project file. Multi-track timeline with nested sequences and automatic backups, proxy editing on modest machines, multicam and three-point editing, a mixer with voiceover recording, automatic subtitle transcription, and hundreds of keyframable effects. Version 26.08.1.

A tool of a few tens of megabytes for the jobs that do not need a timeline: cut the title off, take the advertisement out, change the format. With both outputs set to Copy, everything between the two markers is kept without being encoded again, so a trim of several minutes takes seconds and the picture is untouched; the price is that a cut has to fall on a key frame. Frame accuracy is a switch away.

An open-source tool that routes an Android phone's audio to a computer over Wi-Fi or USB and presents it as a normal microphone, with noise suppression, automatic gain and de-reverb built in. Runs on Windows, macOS and Linux.

An open-source image viewer for Windows, macOS and Linux that reads more than ninety formats, from HEIC phone shots and camera raw files to WebP, AVIF and JXL. Free for personal and commercial use, with no advertising and no hidden charges.

A graphical shell around a very capable command line encoder. Format conversion, audio extraction and simple cutting become form fields and buttons, which means the power underneath is available to people who would never type the commands.

A recorder that keeps the setup short: pick a region, a window or the whole display, decide where the sound comes from, and start. Recordly adds annotations while the capture is still running and exports the result in whichever format the destination needs.

HandBrake is a free open source transcoder for Windows, macOS and Linux. Its usefulness is not that it converts video — everything does — but that it lets you see and change the trade between quality, size and time that a preset would otherwise decide for you.
