LANShare v1.2

LANShare v1.2.0 — Soundboard Update

Play sound effects for everyone in the room with your own library of sounds.

---

Highlights

• Soundboard: play short sound effects for everyone in the room
• Build your own sound library from .mp3, .wav or .ogg files
• See who played the sound: their name lights up in the users list
• Per-user sound effects volume, independent from the stream volume
• Anti-spam cooldown so nobody can flood the room

---

Soundboard

• New 🎉 button at the bottom center of the video, available to the Host (with the room open) and to connected Clients
• The button stays discreet until you hover over it, then grows and lights up
• Click it to open the sound effects panel, with 3 sounds per row and scrolling for bigger libraries
• Click a sound to play it for everyone in the room: you hear it instantly, and so does everybody else
• Up to 4 sounds can play at the same time
• In fullscreen, the 🎉 button hides together with the volume button when the mouse is idle

Your Sound Library

• Click Add sound to open the new add dialog, or drag a file straight onto the panel
• Supports MP3, WAV and OGG files, up to 5 seconds and 2 MB
• Preview the sound before saving it
• The file name is used as the default name, and you can change it. Tip: paste an emoji into the name (e.g. Quack 🦆)
• Sounds are saved on your computer, in %APPDATA%\LANShare\sfx, and stay there between sessions
• Right-click a sound to Play only for me, Rename or Remove it
• Clear error messages for files that are too long, too big or in an unsupported format

Who Played It?

• When someone plays a sound, their entry in the users list gets a blue border and a 🎉 while the sound plays
• Works for everyone in the room: Host, Clients, and the person who played it
• Play only for me doesn't light up anything, since nobody else hears it

Sound Effects Volume

• New volume icon in the corner of the panel opens a horizontal slider above it
• Hover to show it, or click to pin it open
• Adjust with the mouse wheel, too
• Each person controls how loud the sound effects are for them. It doesn't affect anyone else
• Separate from the stream volume, saved between sessions (starts at 70%)
• Sound effects play on the output device chosen in Settings

Anti-spam

• After playing a sound, there's a 1.5 second cooldown before you can play another one
• The panel shows a small bar counting down the cooldown
• The Host enforces the rule for everyone, so a modified client can't flood the room

Under the Hood

• Sound effects are compressed with Opus (48 kHz, stereo) before going over the network. A 5-second sound takes about 60 KB
• The Host validates every sound it receives (size, length and name) before passing it on
• Sound effects played by LANShare are not captured into the stream audio, so nobody hears them twice

Fixes

• Host users list: with many users in the room, the list no longer overflows onto the buttons below it. It now uses the available space and scrolls

LANShare v1.1

LANShare v1.1.0 — Audio Update

Everything playing on the Host's computer reaches every viewer in the room, in sync with the image.

---

Audio Streaming

• Captures everything playing on the Host's computer

• Audio starts and stops together with the screen stream
• If the audio fails, the image keeps going and a warning is shown

Audio & Video Sync

• Audio and video are timestamped at capture, on the same clock
• The Client uses the audio as the master clock and paces the video to it

• New A/V offset indicator in the Client's info bar

Audio Output

• Choose where the stream's sound plays in Settings → Audio & Notifications
• Windows default follows the system if you change the default device
• Switching the output takes effect instantly, even while watching
• If the chosen device is disconnected (e.g. headphones), sound falls back to the Windows default and returns automatically when it's plugged back in

Volume Control

• New volume button in the corner of the video (Clients only)
• Vertical slider with live percentage, plus a mute toggle
• Adjust with the mouse wheel over the button
• Volume and mute are saved and restored on the next launch (starts at 50%)
• In fullscreen, the button and cursor hide when the mouse is idle, like a video player

Fixes

• Fullscreen now exits automatically when the Client disconnects or is removed from the room
