// getting-started

Activate LiveAudio in four real steps.

Install the app (or run the portable exe), let the first run fetch transcription models, let LiveAudio auto-detect your GPU, then pick a profile and START SYSTEM. No Python runtime to provision. Internet is needed only on the first run; after that it is 100% local.

ACTIVATION SEQUENCE

  1. // get

    Get LiveAudio — installer, portable, or source.

    Most people just download and run. Three real paths: the graphical installer (recommended), the portable standalone exe, or building from source if you are a developer.

    Linux: legacy v1.2.7 build

    // installer

    Installer (recommended)

    Windows x64: download LiveAudio_1.5.1_x64-setup.exe and run it — no Python to install, the app is a native Rust binary. Coming from v1.0.0–v1.2.7? The installer removes the legacy Python build silently and preserves your settings in %APPDATA%\LiveAudio. Prefer no install? Grab liveaudio-desktop.exe (~16.2 MB) and just run it. Linux: use the legacy v1.2.7 tarball for now.

    windows x64
    # Installer (recommended) or portable:
    LiveAudio_1.5.1_x64-setup.exe
    liveaudio-desktop.exe
    

    Windows: not code-signed yet

    // source

    Build from source (Rust + Tauri 2)

    Clone the repo and follow the build instructions in the repository README (Rust toolchain + Tauri 2 prerequisites). This path is for developers; everyone else should use the installer.

    git · developers
    git clone https://github.com/plynte-labs/LiveAudio.git
    cd LiveAudio
    

    Legacy Linux tarball (v1.2.7) needs libportaudio2 (sudo apt install libportaudio2).

  2. // first-run

    First run fetches the models.

    The first launch downloads the transcription models, then caches them. Models download on first transcription. Every later start is instant and fully offline.

    First run: internet required

    No Python, no pip chain: the installer (~26.2 MB) is the whole app. Your settings and sessions in %APPDATA%\LiveAudio survive updates and the Python-to-Rust migration.

  3. // detect

    LiveAudio auto-detects your GPU.

    A GPU is optional — the CPU works. On launch, LiveAudio checks for a usable NVIDIA CUDA GPU and falls back to CPU automatically. You can always override the choice.

    • CUDANVIDIA driver ≥ 525 and VRAM ≥ 4 GiB → CUDA is used.
    • CPUNo usable GPU → CPU is used automatically. No setup needed.
    • overrideYou can force CPU or CUDA yourself before starting.

    GPU optional; CPU works. CUDA needs driver ≥ 525, VRAM ≥ 4 GiB.

  4. // go

    Pick a profile, then START SYSTEM.

    Choose an FPS-aware profile, pick your audio device and CPU/CUDA + model, click Apply changes, then START SYSTEM. Speak — captions appear and stream to OBS over the local WebSocket.

    • Fastlow latency
    • Balancedrecommended
    • Qualityhigher accuracy, more VRAM
    • Stable Streamingreduces GPU load while gaming

    Editing a built-in profile creates a Custom one. Apply changes to activate.
