Is my voice recorded or uploaded?

No. Audio is analysed in real time on your own device and immediately discarded. Nothing is recorded, stored, or sent to any server — close the tab and it is gone.

How does it find my Sa without being told?

It weighs every note you sing by how long you dwell on it, with extra weight for the notes you rest phrases on — singers naturally return to their tonic. Once one pitch clearly leads, that becomes your Sa, shown with its frequency in Hz.

For solo singing or humming in a reasonably quiet room, pitch tracking is accurate to a few cents and note identification typically exceeds 95% — browser noise processing is disabled, low-confidence frames are gated, and glides are kept out of the analysis. Accuracy drops with heavy background noise or Bluetooth headset mics.

Can it identify the scale of a song playing on speakers?

Song mode estimates the key from a pitch-class profile of the audio. Polyphonic music is a fundamentally harder read than a single voice, so it is framed as a strong guess rather than a verdict.

Why is the detected scale a different letter than the song’s original key?

Because the mirror names the scale in YOUR key. Nearly everyone transposes songs into their comfortable range — sing an E♭-major song from D and the scale family is identical, only the letter moves. Set the optional “Original key” in the panel and the mirror shows exactly how far you’ve transposed.

What if my singing isn’t pitch-perfect?

The mirror tunes itself to you, not the piano: it tracks your personal reference as it drifts and names notes relative to it, so consistently-flat or sharp singing still reads as the scale you meant. When one note runs persistently off, it tells you which one and by how much.

Svara Mirror

Sing or hum into your microphone and watch your melody draw itself as a live pitch trail while Svara Mirror finds your tonic on its own and names the raga or scale you are singing — in Carnatic or Western terms. When two candidates are close, it tells you which single note settles it. A Song mode estimates the key of music playing nearby. Everything runs on your device: nothing is recorded, stored, or uploaded.

How to use Svara Mirror

Tap "Enable microphone" and allow access — or tap "Watch a demo" to see the mirror run on a simulated voice first.
Start by holding your Sa: one steady note for a couple of seconds anchors the mirror to your voice.
Sing or hum slow phrases, holding notes at least half a second. Your melody draws itself as a glowing pitch trail, and the big readout names each note with a cents gauge.
Keep singing — the mirror finds your Sa (tonic) automatically and ranks the ragas or scales that match, sharpening as it hears more of you. Or pin your Sa with the Fixed toggle.
Toggle the built-in tanpura for a soft drone at your Sa — the classic way to hold your shruti while you sing.
When two candidates are close, follow the hint: it names the one note that settles the tie.
Switch to Song mode to estimate the key of music playing near the mic, or toggle Carnatic/Western to change the vocabulary.
