Tune between songs in 50ms. Monitor your stream's frequency balance in real time. Lock to a click without leaving the browser. No installs, no licenses, no subscription.
Streaming live music — covers, loops, instrumental sets — needs the same tools the touring rig has, minus the rack and the budget. SignalKey's live tools run on-device in any browser, so you can tab between Tuner, Metronome and Spectrum Analyzer without breaking the stream.
Every tool below is free, no signup, no watermark. Click any card to open it.
±0.1 cent accuracy, 50 ms response. Tune electric bass, acoustic guitar or orchestral instruments between songs without dropping the stream.
Compound time signatures (6/8, 9/8, 12/8) and triplet / dotted-eighth subdivisions. Lock the click in your IEM or headphones, off-stream.
Real-time frequency monitor of the stream output. Catch room resonances, instrument bleed or feedback before chat does.
Capture a tempo by ear when chat requests a song you don't know — match your loop pedal in seconds.
Move a backing track to your key when chat asks for a key swap — no need to load a different file.
How a music streamer keeps the rig tight across a 3-hour set.
Before going live, open Spectrum Analyzer with the room mic. Identify low-end build-up (60-120 Hz boom) and tame it on your interface EQ before viewers join.
Between songs, tab to Tuner. Verify open strings on bass and guitar in 5 seconds. ±0.1 cent precision means no drifting intonation halfway through a 4-hour stream.
Viewer requests a song you don't know. Tap Tempo while you listen to the original on a side device. BPM in seconds. Match your loop pedal, play it.
Keep Spectrum Analyzer open in a second tab. If the chat says 'audio is muddy' you can verify in real time — most likely a room resonance or a bleed issue.
“Tuner, metronome, spectrum — all in one browser tab. I dropped a $400 hardware tuner and a $200 mic monitor and the stream sounds tighter than it did before.”
— Music-streaming workflowNo — the Tuner needs mic input to detect the played pitch. iOS Safari, Chrome and Firefox all prompt for microphone access on first use.
