IEM mix management
for live bands
Each musician controls their own headphone mix from their phone — just scan a QR code, no app install needed. Real-time faders, effects, click track, and multitrack recording in one native macOS app.
Engineer View — Full mixer with faders, meters, effects, and transport
Everything you need on stage
Built from the ground up for live performance, with real-time audio processing in Rust.
Real-Time Mixer
Per-channel volume, pan, mute, and solo with instant sync. Every musician gets their own independent mix.
Audio Effects
3-band parametric EQ, compressor, and reverb per channel. Factory presets included for quick setup.
Click Track
Sample-accurate metronome with 3 sound presets and downbeat accents. Each musician controls click volume independently.
Multitrack Recording
Record all inputs to WAV or MP3 with pre-roll count-in. Lock-free encoding with zero impact on audio quality.
Designed for the stage
The Musician view is built mobile-first. Big touch targets, instant feedback, zero learning curve.
Large 44px touch targets with instant visual feedback. No waiting for server round-trip.
Star the channels you use most. They stay pinned to the top, saved per bus in your browser.
One tap to silence your entire IEM mix. Quick way to take out your in-ears without disconnecting.
Adjust click track volume or mute it entirely — independently from every other musician.
See the current section (Intro, Verse, Chorus) at a glance in the colored mini-timeline.
Faders & Favorites
And more
Everything else you need for a professional live rig.
Up and running in minutes
No complex routing, no extra hardware. Just your Mac, your audio interface, and WiFi.
Set up your channels
Launch ESTË Live, select your audio interface, and name your input channels and output buses. Load backing tracks and configure tempo.
Share the QR code
Open the QR code dialog and let each musician scan it with their phone. Approve each device with one tap, and they get a mobile-optimized mixer view for their own IEM bus.
Everyone mixes their own
Each musician adjusts their personal mix in real time — volume, pan, mute, favorites. The engineer controls the main FOH mix and transport.
