Sailwind Radio

Play your own music in Sailwind through a physical radio and speakers with 3D audio.

Install

Mod managers

Install Sailwind Radio on Thunderstore through r2modman or Thunderstore Mod Manager, then launch Sailwind through your manager. Dependencies are installed automatically.

Manual installation

1. Install BepInEx 5 in your Sailwind game folder, following its installation instructions.
2. Download and extract the Sailwind Radio ZIP. Copy its BepInEx/plugins/SailwindRadio folder into BepInEx/plugins in your Sailwind folder.
3. Launch Sailwind normally.

Controls

• Use the radio's physical Power, Previous, Pause, Next, Shuffle and Collections buttons to control playback.
• For volume knobs, click on the knob and scroll to adjust it, then click again to release it.
• On the radio, master volume controls all connected outputs, while local volume controls only the radio's built-in speaker.
• Pick up, carry, store and place the radio using Sailwind's normal item controls. Music keeps playing while the radio is carried or in inventory.
• Place a hook somewhere clever and set the radio in a tight corner, or hammer it down if you keep grabbing it off your shelf trying to skip tracks. The Aestrin radio has no handle, so it won't hang from hooks.
• Turning on a second radio turns the one currently playing off. Each keeps its own folder selection, volume, and song position saved.
• Turn a radio off and back on to reload its selected music folders after adding songs.
• With ShowSongOnHover turned on, look at a radio to see the song it is playing.

Configuration

After the first launch, close the game and edit BepInEx/config/local.sailwind.radio.cfg in your active game or mod manager profile. With Configuration Manager installed, the audio and display settings can also be changed in game.

Example folder setup: MusicFolders = D:\Music | E:\Sailing Music. Each folder is one collection, including music within its subfolders. The radio reads file metadata to display title, artist and album tags, and uses the filename when a title tag is missing.

Supported formats:

• MP3, OGG (Vorbis), WAV and FLAC files.
• M4A and AAC files on Windows. These file types are currently turned off automatically on Steam Deck and Linux (Proton).

Sample rates up to 192 kHz are supported, and surround files are mixed down to stereo.

Shop Locations

There are added shop stalls in Gold Rock City, Dragon Cliffs, Fort Aestrin and Chronos. Gold Rock City sells the Al'Ankh set, Dragon Cliffs sells the Emerald set, Fort Aestrin sells the Aestrin set and Chronos sells the original walnut set. GRC's stall is between the shipyard and port office, DC's is near the boxed food seller, FA's is near the Inn and Chronos's is under the empty tent in the main market square.

Speakers

Device	Sound	Audible range
Radio	Small, built-in speaker	12 m
Small Speaker	Compact speaker with its own power and volume	15 m
Speaker	Clearer cabinet with its own power and volume	20 m
Turbo Wolfer	Bass-only cabinet with power and bass level	20 m

Speakers connect automatically to an active radio within 50 metres when both are on the same vessel or both are ashore. The Small Speaker can mount on surfaces like a hook does. Each output gets quieter with distance, and cabins/some interiors muffle sound across their boundaries.

Each regional set has the same four device roles and audio behavior. The regional radios use their own mechanical title and artist displays: character drums in Al'Ankh, split flaps in Aestrin and a writing scroll in Emerald.

Set	Radio	Small Speaker	Speaker	Woofer

Al'Ankh	43044	43045	43046	43047
Aestrin	43048	43049	43050	43051
Emerald	43052	43053	43054	43055
