StreamLite

A clean mic, 3D game audio and better-sounding headphones - free, for Windows and Linux.

StreamLite sits between your microphone and Discord, OBS, Zoom, TeamSpeak or your game and removes keyboard clicks, fans, PC hum, traffic and room noise with AI. It also turns games' 7.1 surround into 3D sound for your headphones, corrects your headphones to sound neutral, and switches headphone profiles for games, music and voice chat on its own.

What it does

• Clean microphone. Voice isolation is built in: DeepFilterNet 3 (studio quality, on your graphics card on Windows) takes out fans, keyboards, traffic and even a loud machine next to you. Includes a noise gate, auto level, compressor, de-esser and EQ. Apps pick StreamLite Mic as their microphone, and your real mic stays usable by other apps.
• Studio voice. Any mic made to sound like a broadcast mic: it learns how your voice comes through this mic, takes out the mic's colouring (thin, boxy, harsh, muffled), rebuilds the treble cheap mics cut off and catches plosive pops.
• Record a sound to remove. A TV, kids or music that noise removal lets through: stay quiet for 8 seconds while it plays, and StreamLite learns it and takes it out of your mic.
• Tune to your voice. Five short recordings (at your mic, further away, loud, quiet, your silly voice), read like a teleprompter: big text, each word turns green the moment you say it. Then StreamLite sets itself up for your voice with the best noise removal and quality your PC can run.
• Only my voice. Someone else talking in your room (a girlfriend, a brother) is turned down: a speaker-recognition model learns your voice (your silly voices too) and tells it from theirs.
• Across the room. Talking from your bed with the mic on the desk: your voice comes out as loud as at the desk, with fans still taken out. A toggle, off for people who talk right at their mic.
• Guided setup. The first time StreamLite opens it takes over your primary monitor and walks you through everything, one step at a time: your mic and headphones (or bring settings in: scan for kept ones, or import a file - just the parts you pick), the headphone EQ engine (on Windows Equalizer APO, installed and switched on for you), Tune to my voice from your mic's raw sound (then hear it tuned, or tune again), your headphones' EQ, Personalize 3D and your camera. Click any step along the bottom to go back to it. Leave half way and it picks up where you left off next time. Updating with your settings saved? Keep my settings skips it.
• 3D game audio. Games' 7.1 surround becomes 3D sound on any headphones, using 20 measured heads at full resolution (SADIE II: the KU100 and KEMAR dummy heads with 8802 directions each, and 18 real people). True 360° placement, footstep boost and a loud-sound tamer. Open sphere takes out walls and floors: footsteps come straight from their direction, never muffled. A live sound sphere shows where sounds come from around you; drag it to look from any side. StreamLite is the audio engine: game and app sound plays through it straight to your headphones on the lowest-delay path (Direct to headphones is built in), and Discord's full-screen share still gets the sound. 16D for music apps or for all apps is one choice.
• Personalize 3D. You fly into the sphere and someone walks in one spot in front of you, behind, left, right, above or below - with Counter-Strike 2's own recorded footsteps when CS2 is installed. Every footstep starts with you facing forward; snap the view to where you hear them and click. In about 4 minutes it finds which of 20 measured heads fits your ears, then tunes your head size, cue sharpening and floor contrast. Practice mode plays the same test with your current settings, without tuning anything, for as long as you like.
• Headphone correction for (almost) every headphone. StreamLite recognises headsets by name and uses their measured correction by itself. "Find my headphones" searches thousands of AutoEq measurements and, behind them, squig.link's ~150 reviewer databases (gaming headsets like the HyperX Cloud III, Razer BlackShark V3 or Corsair HS80 included) - StreamLite makes the EQ from the raw measurement. Still missing? Missing? Report it opens a ready-made report.
• Automatic profiles. Each game gets its own headphone EQ. Music applies while Spotify plays, Chat applies while Discord, Zoom, Teams, TeamSpeak, Mumble or another chat app is open, and Movies & videos applies otherwise. Presets together plays them at the same time: your game's preset on the game's sound and Music's on Spotify.
• AI camera (Windows 11, Linux with v4l2loopback). A "StreamLite Camera" virtual webcam with background blur, AI green screen and auto light, that works like an AI gimbal camera (Insta360 Link 2 style) with any webcam: tracking one person or a group, head / half body / whole body framing, hand gestures (each with its own switch), air drawing (make a V, then write in the air with your index finger), camera animations (flip upside down, spin, roll, zoom punch, shake), tracking and pause zones, presets, whiteboard and desk view, levelling, upside-down mounting, HDR, face exposure and privacy.
• AI quality (Settings). One choice for voice isolation and the AI camera: Low VRAM (about 210 MB of video memory), Normal (about 430-490 MB), High VRAM (about 860-890 MB, the camera's cut-out at full HD) or Full CPU (no video memory, slowest).
• Any headset, any mic.
  • USB, Bluetooth and analog headsets, audio interfaces and array mics all work.
  • Auto picks the mic input that carries your voice.
  • Each headset keeps its own correction, and each mic its own settings (also as a file for a friend's PC).
  • Your setup, piece by piece: export or import every setting - or just a device, an area or single settings (noise gate, one game's headphone EQ, a camera's picture settings) - as a file that holds no device IDs, paths, voiceprints or recordings.
  • Plug in or unplug devices and StreamLite follows.
• Hotkeys for everything. Mic, outputs, 16D, 3D and camera actions (flip upside down, spin) on any key or mouse button.
• Takes care of itself. It installs the free drivers it needs on Windows (and what it needs from your distro on Linux), updates itself when it starts, and has a Report a bug button.
• Private. Recordings - Tune to my voice, Record a sound to remove, Test your voice - stay in memory and are thrown away once used; nothing you say is ever saved to disk. Only my voice keeps a voiceprint (numbers, not sound) only while it's switched on.
• The same app on Linux. Every page and feature of the Windows app, on any distro with PipeWire or PulseAudio.

Install

System	Download	How
Windows 10/11 (64-bit)	StreamLite-<version>-x64.msi	Double-click it. Windows SmartScreen may say "Windows protected your PC": click More info → Run anyway (StreamLite isn't code-signed yet).
Linux (Ubuntu, Debian, Mint, Pop!_OS, Fedora, Nobara, Bazzite, openSUSE, Arch, Manjaro, CachyOS...)	StreamLite-<version>-linux.sh	bash StreamLite-<version>-linux.sh - installs StreamLite for you and what it needs from your distro (asks for your password once). --system installs it for everyone.

Or the same in one line:

curl -fsSL https://raw.githubusercontent.com/NermalYT/StreamLite/main/packaging/linux/get.sh | sh

From 4.1.4 these are the only two installers. A portable (zip) copy of an older StreamLite moves to the MSI when it updates (your settings stay). On Linux, a 4.1.2-or-older install (.deb, .rpm, AppImage, tarball, Arch package) is replaced by running the .sh once; StreamLite updates itself after that.

Linux needs PipeWire (with pipewire-pulse) or PulseAudio, which every mainstream desktop has. The installer adds Mono (which runs StreamLite), ffmpeg, v4l-utils and v4l2loopback (for StreamLite Camera) from your distro.

Quick start

1. Start StreamLite. The guided setup opens by itself and does the mic, voice, headphone EQ and 3D audio for you (about 6 minutes).
   • On Windows, click Install VB-CABLE (free) if StreamLite asks for it. It's the virtual cable your clean mic travels through.
2. In Discord, go to Settings → Voice & Video and set Input Device to StreamLite Mic. Set Discord's own noise suppression to None and turn off its automatic gain control, so your voice isn't processed twice. OBS, Zoom, TeamSpeak and games work the same way.
3. Optional:
   • Headphones → Find my headphones corrects your headphones.
   • 3D Audio gives games 3D sound. Set the game's audio output to 7.1 / surround.

The manual covers everything else, with fixes for common problems.

Bugs and ideas

Use Report a bug in StreamLite. It's in the sidebar, under Settings, and in the tray menu: pick the kind of problem (or an idea), say what happened and how to make it happen, and Send posts it on StreamLite's issue list with your version and system. No account needed.

• Screenshots of StreamLite or an error are shown on the report once they've been checked to be family friendly. Anything else is left out. Bad language in reports is starred out.
• Videos aren't uploaded. Tick "I have a video" and the developer will ask you for it on Discord.
• Your Discord name (optional) is seen only by the developer, never on the public report.

The reports go through a small free service, cloudflare/report-worker. Reports by hand are welcome too: bug form, ideas.

Building it yourself

• Windows: run .\build.ps1. It uses the C# compiler that ships with Windows, so no SDK is needed. Then:
  • .\install.ps1 installs it for your user.
  • .\packaging\windows\build-msi.ps1 builds the MSI and the zip. This needs the .NET SDK and WiX 5.
  • .\test\all.ps1 runs the offline tests.
• Linux: the same sources, built on Windows: .\packaging\linux\make-installer.ps1 builds the Linux program (linux\mono-bin\StreamLite.exe, for Mono) and the one-file installer dist\StreamLite-<version>-linux.sh. test\linux-lab\lab.ps1 up starts a Linux desktop in Docker with test headphones and mics to try it on.

Pushing a version tag (v2.1.0) makes GitHub Actions do the following:

• Build everything and run the tests.
• Install the Linux installer on Ubuntu, Debian, Fedora, openSUSE and Arch.
• Publish the release with SHA256SUMS.txt, which the updater checks.
