Shruti Laya
iOS Universel / Musique
Shruti-Laya is a Carnatic music practice companion. Three independent,
perfectly phase-locked voices — tanpura, mrudangam, and manjira — play
together against the tala grid you choose, for steady, musical
accompaniment any time.
TANPURA DRONE
• Choose your tonic (Sa) across a wide range and the supporting string —
pancham (Pa), madhyama (Ma), nishada (Ni), or upper Sa.
• Adjust pluck rate and volume.
MRUDANGAM
• Tala-driven stroke playback with adjustable tempo (40–150 BPM).
• Optional pattern variations for a more lifelike accompaniment.
MANJIRA
• Cymbal strokes on every beat, on claps, on sam, or off.
PICK YOUR TALA
• All seven Suladi Sapta Talas — Dhruva, Matya, Rupaka, Jhampa, Triputa,
Ata, Eka.
• Set jaati and gati/nadai — Tisra, Chatusra, Khanda, Misra, Sankeerna —
plus a kalai multiplier. (Adi tala = Triputa with Chatusra jaati.)
BUILT-IN TUNER (new)
• Tune your voice or instrument to your selected tonic.
• Live swara name and a sharp/flat cents bar, right in the display.
Practice-friendly: pause and resume from the lock screen and Control
Center, and the drone keeps playing when the screen sleeps. Works on
iPhone and iPad.
NOTE: The Tuner feature uses the microphone to detect the pitch of the user's
voice or instrument and show how it compares to the selected tonic. Tap
"Tuner" above the on-screen display to try it; the app requests microphone
permission on first use. No audio is recorded, stored, or transmitted.
Quoi de neuf dans la dernière version ?
- Double-speed strokes are now possible. StrokeSpec.matraOffset changed from Int to Double, so a stroke can land between two matras (e.g. 24.5). adiCadence's beats 7–8 now play at double density (8 strokes instead of 4) as a worked example.
- Cadence plays more often. The Mrudangam variation phrase length dropped from 8 avartanas to 2, so the cadence-into-sam now shows up every other avartana instead of every 8th. (Trade-off: the other two Adi variations — "Ornamented fingers" and "Ta dhin dhin na" — no longer get a turn, since the only non-base slot is now always claimed by the cadence.)
Rhythm count-in (new feature)
- Pressing Rhythm Play now always plays a 4-click count-in before the avartana starts — and always starts fresh at sam, never mid-cycle from wherever a quick pause/resume left off.
- The LCD (both the small always-on display and the full-screen Performance LCD) shows 4 dots during the count-in instead of a confusing "beat 1": one dot disappears per click, and a "GET READY" label appears in bright yellow.
- The count-in uses the non-clap tick sound, so it doesn't get confused with the actual clap on sam.
- Under the hood, several correctness passes: the dots now track the same audio clock the clicks are scheduled on (so they can never drift out of sync), and a stale-engine-anchor bug that occasionally made the avartana restart at a random beat after a stop/start is fixed.
