ISW Wave
The room
requests back.
Live song requests for halls, hacks, and nights that need a queue — scan, search, approve, play.

Why it exists
Pass-the-phone playlists break. A live wave doesn't.
At uni events and hack nights, everyone wants a say in the music — but DMs, sticky notes, and open YouTube tabs turn into chaos. ISW Wave gives attendees a request lane and organizers a real control room.
How it works
Four beats. One loop.
Search → request → approve → queue → now playing. That's the product.
- 01
Scan
Projector shows Now Playing, the upcoming queue, and a QR that opens the event join page.
- 02
Request
Attendees search YouTube, pick a track, and submit — limits and moderation apply automatically.
- 03
Approve
The tech lead clears the pending list from the control room, with keyboard shortcuts and bulk tools.
- 04
Play
Approved songs enter the live queue. Admin audio drives the hall; display stays informational.
Capabilities
Built through real event nights
From a single-event MVP to multi-tenant organizers — features landed only after they survived the floor.
QR join in seconds
Guests open the event link or scan the hall QR — name + access code, no email signup.
YouTube search, venue-ready
Server-side search with duration filters, quota caching, and graceful limits when the free tier runs hot.
Control room & display
Approve, reject, reorder, and play from the admin laptop. The projector stays silent and always on-brand.
Crowd voting & auto-mod
Pending songs rise by votes. Block keywords, cap length, and flag or auto-reject before they hit the floor.
Themes that match the night
Accent color, logo, and minimal/full display modes so every organizer's event feels like theirs.
Multi-event organizers
One account, many isolated events — each with its own slug URL, queue, settings, and admins.
Three surfaces
