Features

Everything you need to go live with audio — nothing you don't.

🎙️ Audio-first streaming

Live microphone audio encoded to AAC and streamed to Twitch over RTMP. Mute and unmute any time — in-app or from the notification.

🖼️ Static-image video

Pick any image from your device and it becomes your stream's video. Auto-scaled to 1280×720 or 720×1280, black bars, no distortion.

🏷️ Branded default banner

No image? No problem. A built-in Stream Audio Cast banner is generated for you — go live immediately in horizontal or vertical mode.

🔐 Keystore-encrypted key

Your Twitch stream key is encrypted with Android Keystore (AES-256/GCM) and never logged, tracked or uploaded anywhere else.

🔁 Stay on air

Foreground service keeps streaming in the background. Automatic reconnect with bounded backoff if the network drops.

♻️ Live banner swap

Change your banner mid-stream at the next frame — no disconnect, no audio interruption, no reconnect.

How It Works

1

Add your stream key

Paste your Twitch stream key — it's stored encrypted on your device only.

2

Pick a banner (optional)

Choose any image, or skip it and stream the branded default banner.

3

Go live

Tap Start Stream. Your mic goes out live; the image becomes the video track.
