Free, open-source radio automation software for Windows, macOS and Linux, written in Rust.
Playlists, hour markers, smart crossfades, Icecast / Shoutcast streaming and AzuraCast station management in one studio app.
Website · Download · Playlists · Work zones · AzuraCast
RadioMaster uses a classic broadcast-automation layout: playlist tabs in the centre, transport, VU meters and the Last / On Air / Next tiles on top, panels around it, and tools in their own windows.
Everything is on the latest release page.
- Download
RadioMaster-Setup-<version>.exeand run it. You can install just for yourself (no admin needed) or for all users; you get Start-menu and desktop shortcuts and an uninstaller. - Prefer no installer? Download
RadioMaster-<version>-windows-x64.zip, unzip it anywhere (a USB stick works) and runRadioMaster.exe.
Embedded web panels use the Microsoft Edge WebView2 runtime, which Windows 10/11 already include.
Download RadioMaster-<version>-macos.zip, unzip it and drag RadioMaster.app to Applications. The app
isn't signed by Apple, so the first time right-click it → Open → Open. Allow the microphone when asked
if you use the mic for talk-overs.
Download RadioMaster-<version>-linux-x64.tar.gz, then:
tar xzf RadioMaster-<version>-linux-x64.tar.gz
cd RadioMaster-<version>-linux-x64
./RadioMaster
It needs ALSA (libasound2) and an X11 or Wayland desktop, which desktop distributions already have.
You create the local administrator account, then add your music with File → Add library folder…. RadioMaster tells you when a new version is out (the button next to the logo); installed copies update themselves in one click.
For a station that runs on its own on a Linux or Windows server, download
RadioMaster-Server-<version>-linux-x64.tar.gz or RadioMaster-Server-<version>-windows-x64.zip
and follow Installing RadioMaster Server below.
Double-click run-windows.bat (or cargo run --release in this folder).
build-windows.bat produces target\release\RadioMaster.exe (with the RadioMaster icon).
build-installer.bat also makes dist\RadioMaster-Setup-<version>.exe (needs Inno Setup 6).
Linux: sudo apt install build-essential libasound2-dev pkg-config, then cargo run --release.
macOS: install Rust, then cargo run --release.
Settings, playlists, layout and history.csv live in %APPDATA%\RadioMaster (settings from an older
OpenBoss install are copied across on first start). If the program ever crashes, the reason is in crash.log there.
- As many playlist tabs as you like (the ▶ tab is on air). Double-click a tab to rename it; right-click for Put on air, Duplicate, Save/Load M3U, move, Clear, Close. Playing any row of another tab puts that tab on air.
- Columns: #, Track Title, Duration, Start time (projected air time, hour markers included), Last played, Type.
- Right-click rows: Play now, Track editor / Edit…, Move up/down, Copy/Move to another playlist, Upload to AzuraCast, Remove.

Playlist events: to stop a scheduled show ending in dead air, finish its playlist with an event row "Put a playlist tab on air → Main"; Main carries on where it left off. End Main with "Play the on-air playlist again from the top" to keep it looping.
Hour markers: wait (silence until the time if early), soft (finish the current track, then jump) or hard (cut in on time). The clock shows the countdown to the next marker.
View → Work zones, the 1 2 3 buttons, or Ctrl+1/2/3 set how many panels the main window has (1 = playlist + left panel, 2 = + right panel, 3 = + lower-right panel). Ctrl+4 / ➕🗖 opens an Additional window — a real window with its own tabbed panel. Open as many as you like and put them on other screens; they reopen where you left them. Each panel's ➕ adds AUX Playlist, Cart wall, Search, Scheduler, File Explorer, Notepad, Statistics, Song Requests, Playback Queue, Log, Library, Clock, Track Info or a web panel. Right-click a tab to move it to another panel or into a new Additional window.
Web panels: type an address and give the tab a name. ➕ → New web panel adds as many as you like. On a fresh install the first one opens https://radiomanager.dovafm.com.
Connection: server address + station (or Find stations on this server). Now playing and listener counts need no key. With an API key (AzuraCast → your account → API Keys) you also get: Overview (start/stop/restart AutoDJ and broadcast server, skip, disconnect live DJ, restart broadcasting) · Queue (remove) · Requests (pending list, delete, clear, add to the local playlist, request songs) · Playlists (enable/disable, reshuffle, queue) · Media (browse, upload here, new folder, queue next, delete) · Streamers/DJs (add, edit, delete, fill encoder) · Listeners · History · Schedule. The Song Requests panel tab shows the same request list.
- AzuraCast → Streamers/DJs: create an account (or do it in the manager) and note the DJ port.
- Tools → Streams → AzuraCast DJ preset, fill host, port, username, password → Connect.
Two-deck crossfading with smart fading and a waveform track editor (cues, fades, intro/outro), cart wall, mic with ducking, multiple outputs, 12-band EQ / compressor / leveling, ad scheduler, event scheduler, rotations, reports, metadata export, remote control HTTP API, station profiles, local operator accounts.
Rules say what plays (an advert / jingle folder, chosen files, or the Adverts list), how often (after every N
songs, every N minutes or hours, or at set times) and when the rule is in force (dates, days, hours). The Adverts
list holds your adverts with the dates and days each may run. Rules can also be used in the playlist generator
(as a pattern step or inserted every N minutes) and run by the Event scheduler or the RULE <name> command.
At a set time (on chosen days and dates): generate a new playlist from a template, append one, play a rule's adverts / jingles, put a playlist tab on air, load an M3U, play a file, start / stop encoders, set the volume, or run any station command.
MP3 is built in. AAC, Opus, Ogg Vorbis and FLAC are made by ffmpeg — put
ffmpeg next to RadioMaster, in the settings folder's ffmpeg folder, or on the PATH, or choose it in Streams.
Custom encoder runs any program you give it: it receives 16-bit 44.1 kHz stereo PCM on stdin and writes the
stream to stdout ({bitrate} is replaced with the bitrate).
- Duplicates: byte-for-byte identical copies, and (optionally) the same song in different files (same artist and title, lengths within 3 seconds). The best copy is kept (lossless, then highest bitrate); playlist rows, cue points and play counts of the removed copies move to it.
- Missing & broken: library tracks and playlist rows whose file has gone are looked for in the library folders (and any folder you add) by file name, then by artist and title, and can be pointed at the file found. Files that can't be played (empty, damaged, not audio) are listed too.
- Genres and Artists: spellings of the same value ("Hip-Hop" / "hip hop", "R&B" / "RnB", "Beatles, The" / "The Beatles", "ft." / "feat.") are suggested for merging, and any spellings can be merged by hand. Untagged files named "Artist - Title" can have their artist filled in.
- Nothing changes until you have looked at the list and pressed Do it. Removed files go to the
Removed tracksfolder in the data folder unless you choose delete for good, and every change is written tocleanup-log.csv.
Pick Everything, Songs, Adverts, Jingles or Speech, voice & other, a period (Today, This week, Last month…
or any dates), and optionally only items containing a word. Click an item to see every time it played.
📄 PDF… saves a report with totals, plays per day and every item; ⬇ Export also has CSV (opens in Excel),
every single play, and proof of play PDFs — for the selected advert or jingle, or each item on its own page,
with every air time and lines to sign. Plays are read from history.csv in the settings folder.
The 🎤 Mic button (Ctrl+M) puts your input on air. Right-click it (or Settings → Audio) to choose what the music does meanwhile: lowered to the level of the slider next to the mic volume, muted, or paused until the mic goes off.
Small programs in any language that run when something happens on air, and can send commands back. See PLUGINS.md and Tools → Plugins.
Settings → General → Language. To translate RadioMaster, see lang/README.md.
File → Users: administrators can add operators and choose what each one may do — playback, jingles, editing playlists, streaming and settings — and exactly which tools they can open (track editor, generator, adverts, Audio FX, AzuraCast, reports, history, notepad, plugins, scheduler, voice tracks, library, file explorer, song requests, web panels). They can also reset passwords and disable or delete accounts.
RadioMaster Server runs the station without a window on Linux or Windows Server: playlists, scheduler, adverts, streaming and, if you want, its own sound cards. Presenters run it from the desktop app with File → Connect to Server. RadioMaster offers to save your local session as a station profile first and brings it back when you disconnect; while connected, a green button with the station's name sits next to the logo, and File → Server settings… changes the server's name, sound output, password, HTTPS and web portal. Connect to Remote Server… on the login screen signs straight in to a server, without a local account. The optional web portal runs the station from a browser on a port you choose.
Linux (Debian/Ubuntu shown; any x64 distribution with glibc 2.35 or later works):
sudo apt install libasound2 # ALSA, usually there already
tar xzf RadioMaster-Server-<version>-linux-x64.tar.gz
cd RadioMaster-Server-<version>-linux-x64
sudo cp RadioMaster-Server /usr/local/bin/
# run it as its own account, as a service
sudo useradd --system --create-home --home-dir /var/lib/radiomaster radiomaster
sudo usermod -aG audio radiomaster # only if it should play through a sound card
sudo -u radiomaster RadioMaster-Server --data /var/lib/radiomaster --setup
sudo cp radiomaster-server.service /etc/systemd/system/
sudo systemctl enable --now radiomaster-server
journalctl -u radiomaster-server -f # the station log
Windows Server: unzip RadioMaster-Server-<version>-windows-x64.zip (e.g. to
C:\RadioMaster-Server), open a command prompt there and run RadioMaster-Server.exe --setup. Then run
RadioMaster-Server.exe, or start it at boot with Task Scheduler (At startup, Run whether user is logged on
or not) or a service wrapper such as NSSM. Allow the port (9259) through Windows Firewall.
--setup asks for the station name, the username and password the desktop apps sign in with (at least 12
characters), the port, whether to use HTTPS and whether to turn on the web portal (and its port). To script it,
use --user, --name, --port, --https, --portal, --portal-port and the RADIOMASTER_PASSWORD
environment variable.
Sound: the server plays through its default sound card, or the ones ticked in File → Server settings…
in the app. Switch "Play through the server's sound cards" off (or start it with --no-audio) for a server
that only streams. With no sound card at all it runs on a silent clock, and streaming works as normal.
Connect: in the desktop app, File → Connect to Server…, type the server's address (e.g.
192.168.1.20:9259), the username and the password. Over the internet, turn on HTTPS: give the server
your certificate with --cert and --key (e.g. from Let's Encrypt), or let it make its own, whose fingerprint
the app asks you to trust once.
Web portal: start the server with --setup --portal (port 9260 unless you set --portal-port), then open
http://<server>:9260 (or https://) in a browser and sign in with the server's username and password.
More detail (options, moving an existing station to a server, security): docs/SERVER.md.
Each release also has RadioMaster-<version>-macos.zip (RadioMaster.app; unsigned, so right-click → Open the
first time) and RadioMaster-<version>-linux-x64.tar.gz. Embedded web panels are Windows-only for now; elsewhere
they open in your browser.
