Frostcast

Frostcast is an accessible Windows audio mixer, recorder, and Icecast streaming client. Combine the audio you need, monitor it locally, and send the same mix to one or more recording files or Icecast servers.

Frostcast is built for broadcasters who want a clear, reliable workflow without living in configuration files. It works well with screen readers and keyboards while remaining straightforward for sighted users.

Mix What You Need

Build a live mix from:

• Microphones and other Windows input devices.
• Speaker loopback, for capturing the sound playing through an output device.
• Selected applications, including more than one application in a single source.
• Local audio files and remote stream URLs for background audio.

Each source has its own volume, mute state, stream-only mute, monitoring route, and fade duration. Monitor selected sources through the output device of your choice before connecting an encoder.

Stream, Record, or Both

Send one mixed audio feed to multiple encoders at once. Frostcast can stream to Icecast and record locally at the same time, with support for AAC, FLAC, MP3, Ogg Vorbis, Ogg Opus, and WAV recording.

Create profiles for recurring setups, such as a radio station stream, a game and voice-chat recording, or a microphone-and-music broadcast. Each profile keeps its own sources, encoder settings, monitoring choices, and shortcuts so it is ready when you are.

Designed for Fast Operation

The mixer is the main screen. Connect and disconnect controls are easy to reach, and the session status reports encoder connection state, bitrate, monitoring, and elapsed time without turning into a noisy log.

Custom shortcuts can control connection state, selected encoders, source mute, monitoring, and source volume. They can work inside Frostcast or across Windows while Frostcast is open. Frostcast can also minimize to the system tray and keep mixing, monitoring, recording, or streaming in the background.

Accessible Without Compromise

Frostcast is designed for keyboard and screen-reader use from the start. It uses standard Windows controls, concise labels, normal keyboard behavior, accessible checklist state changes, predictable focus restoration, and readable progress reporting. It is not a separate interface for blind users: the same clear, visible workflow is intended to work for everyone.

Windows-First and Reliable

Frostcast is built specifically for Windows audio. It uses WASAPI capture for microphones and loopback, native Windows process-loopback capture for applications, and bundled FFmpeg for encoding. The mixer continues to run while encoders are disconnected, so monitoring and setup do not depend on being live.

When it is time to broadcast or record, open the profile you need, confirm the mix, and connect. Frostcast keeps the path from setup to a reliable live stream or recording clear and within reach.

Whether you are building a simple live stream or a more involved production, download Frostcast and make the mix your own.
