The Ultimate Music App
Free & open source · public beta 0.1.2WavWiz turns your always-on Windows PC into a whole-home music server. Your library and internet radio play in perfect sync on every PC, TV and phone in the house. Phones join right from the browser. No app to install, nothing to pay.
Per-device delay
Bluetooth speakers, TVs and Wi-Fi PCs each add their own lag, and in a whole-home setup that lag turns into an echo between rooms. WavWiz gives every device its own live delay slider from 0 to 1000 ms, paired with a number box for exact values. Adjust it while the music plays and each room falls into line, so walking through the house sounds like one big room.
Features
Everything the Ultimate Music App should do—fill the house from the kitchen speaker to the phone in your pocket.
Your WavWiz server shows up on iPhone, iPad and Mac as the AirPlay speaker WavWiz – Whole House. Send audio from any app, like Spotify, Apple Music, YouTube or podcasts, and it plays in every room in sync, with title and artwork on Now Playing and the visualizers reacting to the music.
Turn it on in Admin settings and WavWiz appears in Spotify's device list. The server streams straight from Spotify to every room at once. Off by default, and it requires your own Spotify Premium account.
Every speaker plays the same sample at the same moment, so walking between rooms sounds like one big room.
Open the address, tap play. No app store, nothing to install. Guests can join in seconds.
Group rooms into zones and fine-tune the delay on each device to compensate for Bluetooth or TV audio lag.
Throw the music up on the TV. Use your theme's colors or pick your own.
Restyle the whole player to match your setup—Midnight Neon, Ember, Arctic, or Pepecoin—or dial in your own colors.
Search and play internet radio stations, synced across the house just like your own library.
Pop in a disc and rip it to lossless FLAC, straight into your library.
Fill in missing track details automatically so your library stays tidy and easy to browse.
Save your favorite room-and-playlist combos as scenes and start them on a schedule. Wake-up music, dinner time, you name it.
Everyone in the house can add songs from their own phone. One queue, no fighting over the aux cord.
Reach your library away from home over your own private Tailscale network, without opening ports to the internet.
How it works
Download WavWiz for Windows and point it at your music folder. That PC becomes the server for the whole house.
On each PC, TV and phone, open the WavWiz address in a web browser. Group them into zones however you like.
Pick an album, a playlist or a radio station. Every room starts on the same beat and stays there.

FAQ
Yes. WavWiz is free and open source under the MIT license. There's nothing to buy and no subscription. The source code is on GitHub.
The server runs on Windows only for now. Install it on a PC that stays on, ideally the one that holds your music library. Other devices just need a web browser on the same network.
No. Phones join from the browser. Open the WavWiz address, and you can listen, control playback and add to the shared queue. Nothing to install.
WavWiz is an unsigned beta, so Windows SmartScreen may warn that the app is unrecognized. If you downloaded it from the official GitHub releases page, click More info and then Run anyway. Only download WavWiz from the official repository.
Yes, privately. WavWiz supports remote access over Tailscale, so you can reach your library from your own devices without exposing your PC to the open internet.
Yes. AirPlay is built in. Your server shows up as the AirPlay speaker WavWiz – Whole House. Pick it from any app (Spotify, Apple Music, YouTube, podcasts and more) and the audio plays in every room in sync, with the title and artwork on Now Playing.
Yes, two ways. From an iPhone, iPad or Mac you can AirPlay from the Spotify app. WavWiz also offers Spotify Connect as an optional add-on: it's off by default, you turn it on in Admin settings, and then WavWiz appears in Spotify's device list and streams directly to every room. Spotify Connect requires your own Spotify Premium account.
You're on version 0.1.2. Features ship and get polished quickly. If something feels off, open a note on GitHub Issues—bug reports and ideas are welcome.
