A calmer control room

Everything you need.
Nothing you don’t.

Simple enough for a first broadcast, capable enough for a busy karaoke night or internet radio station.

01 / MIX

Two sources.
One clean broadcast.

Blend a microphone or mixer with audio from Chrome, Spotify, KaraFun, or another Windows program. Each source gets its own volume control.

02 / SOUND

Shape the voice, gently.

Add microphone-only reverb, control input volume, and choose a processing preset without changing the backing track.

03 / PEOPLE

Know who is listening.

See live listeners while you broadcast and remember the personal high for every saved station.

LIVE LISTENERS 42 Personal high · 68
04 / DESTINATIONS

Icecast and SHOUTcast, side by side.

Save stations, mark six favorites, switch destinations quickly, or broadcast to several servers at once.

Your shortest route to air

From quiet room
to live radio.

The workflow reads from left to right and keeps every important decision visible.

  1. 01

    Choose your sound

    Select a microphone or mixer. Add one program as a second source when you need music or karaoke playback.

  2. 02

    Listen before going live

    Watch the stereo meters, record a five-second sound test, and compare the original and processed versions.

  3. 03

    Pick a station and broadcast

    Test the connection, enter the artist and title, then press one unmistakable Start Broadcast button.

Start here — no studio experience needed

Choose the setup
that sounds like you.

Follow one short path, check three green lights, and you are ready for your first broadcast. The technical words can wait.

PATH 01 · RADIO

Microphone or mixer

For talk radio, a live DJ, interviews, or a complete mix coming from a mixer.

  1. 1

    Choose Recording device. Select your microphone, USB interface, or mixer.

  2. 2

    Watch the L and R meters. Speak normally and keep most peaks out of the red.

  3. 3

    Test your sound. Record five seconds and listen before anyone else does.

  4. 4

    Add and test your station. Use the details supplied by your radio host.

PATH 02 · KARAOKE

Voice plus backing track

For karaoke with a live microphone and music from KaraFun, a browser, or another audio app.

  1. 1

    Choose Recording device. Select the microphone used by the singer or host.

  2. 2

    Choose Program audio. Start playback, refresh the list, and select KaraFun or your music app.

  3. 3

    Balance both volume sliders. Make the voice clear without drowning out the backing track.

  4. 4

    Test the complete mix. The sound test hears the same combined signal your listeners will hear.

Questions before
you go on air?

Does SimpleCast support Icecast and SHOUTcast?

Yes. It supports Icecast 2, SHOUTcast 1, and SHOUTcast 2 using its compatible source protocol. You can save several stations and broadcast to multiple included destinations.

Can it mix my microphone with karaoke audio?

Yes. Select a recording device and add a running Windows program such as KaraFun, Chrome, or Spotify. SimpleCast mixes both sources with independent volume controls.

Why does Windows warn about the installer?

The beta is not digitally signed, so Windows can show an unknown-publisher warning. Every release includes checksums and build provenance so the download can be verified.

Will SimpleCast tell me when an update is ready?

Yes. Use the Update button in SimpleCast to check GitHub for a newer published version and download its verified installer.
