Sing Together Online.
Actually Together.

The only remote music rehearsal platform that guarantees synchronization for ensembles—no matter where your singers and musicians are.

✓Works in your browser — no software to install
✓Perfect sync from anywhere — distance doesn't matter
✓Simple enough for everyone — even on phones with Wi-Fi

We All Learned During COVID…

…that it's impossible to sing together over Zoom. The result is cacophony — uncontrolled network latencies make real-time vocal synchronization fundamentally broken on standard video calls. Virtual choir projects require hours of post-production editing. Online ensemble platforms demand expensive hardware and ethernet connections.

Existing solutions force impossible choices:

✕Give up on singing together in real-time (virtual choir projects like Smule)
✕Fight latency with expensive gear and technical expertise (JackTrip, specialized hardware)
✕Manually configure delays that change with every session (JamKazam)

There's a better way.

The "Jujitsu" Approach to Latency

We don't fight latency. We sidestep it entirely.

Instead of trying to make the internet fast enough for real-time music — a physics problem no one can solve — we use backing tracks as a shared synchronization reference.

  • ›Upload your backing track
  • ›Set up the session
  • ›Share a simple link with performers

Everyone Sings Together

  • ›Sing or play along with the backing track
  • ›Adaptive synchronization
  • ›Download perfectly aligned recording

How it works technically: Each singer performs alongside the same backing track. Our system automatically aligns all performances with sub-20ms accuracy — regardless of network latency or geographic distance. The result: studio-quality synchronized ensemble recordings without expensive equipment or complex setup.

Common Questions

Zoom is optimized for back-and-forth speech and can tolerate latency. We're purpose-built for music, where synchronization must be precise to the millisecond. Our asynchronous approach guarantees perfectly synchronized output that Zoom simply can't deliver.

No — Lyrekos is designed for structured ensemble performance with backing tracks. If you need real-time jamming, tools like JackTrip or Jamulus are better suited, though they require more technical expertise and specialized equipment.

Just a web browser, a decent internet connection, and basic headphones with a microphone. The same gear you already use for Zoom calls works great. No special audio interfaces required.

Not at all! Singers can be anywhere in the world. Distance and geographic location don't matter — we've tested successfully across 10+ time zones.

Directors spend about 2 minutes uploading a backing track and creating a session. Singers need about 30 seconds for an audio check and they're ready to go.

Yes, backing tracks are essential to how our synchronization system works. You can use professional tracks, create your own recordings, or even use a simple piano accompaniment. The backing track can be removed from the final output if desired.

You're responsible for appropriate licensing of any music you use, just as you would be for in-person rehearsals. Churches with CCLI coverage and educators using TEACH Act-eligible content have existing frameworks that apply.

Yes! Lyrekos works on high-end smartphones and tablets through the mobile Chrome browser. No app download required — just open the link and go.

Standard home internet is typically sufficient. If you can stream Netflix or have a decent Zoom call, you'll be fine. Our asynchronous approach means network quality doesn't affect synchronization.

Yes — a perfectly synchronized recording of your ensemble is automatically generated and available for download after each session.
