The whole band, in one pass
Multitrack a live room
Two overheads on the combo inputs, a bass DI and a guitar on three and four — four sources, four separate tracks, one take. A 2-in interface makes you record the band twice and pretend it was once.

Why we exist
Precision and feeling are not opposites. We build audio hardware for the people making music in India — measured to a standard, and tuned to an ear.
लय — laya, rhythm. राव — rāv, sound. Layarav is both — लय.राव — because neither one is music on its own.
The R4
Three reasons it out-specs its shelf.
The Raag Series begins with an interface that competes on hardware — the part you cannot download later.
Vistār · The expansion
Up to twelve inputs. One optical cable.
Add an eight-channel preamp over one optical cable and the four inputs you bought become up to twelve — at sample rates up to 96 kHz, with the lock state on the front-panel display. In a raga, the vistār is the slow unfolding — the section where a form grows into its full size — and this is the same idea in hardware.

MIDI · Five pins, still standard
Your keyboard did not stop existing.
Full-size five-pin MIDI IN and MIDI OUT on the rear panel. Sync a drum machine, drive a synth, play a controller that predates USB — without a dongle, an adapter, or a hub that drops out mid-bar.

Sur · The preamps
Four preamps. Not two with excuses.
Sur is the note before the raga — the thing everything else is tuned against. The R4 gives you four of them, and every channel takes a microphone, a line source or an instrument.
Read the deep-diveWho it's for
Four inputs change what you can record.
Four separate tracks, in a single pass — the difference between a demo and a record.
Two voices, one room
Podcast and interview
Two microphones with independent 48 V and independent gain, each on its own track for editing. SAFE keeps the guest who leans in from clipping the episode. The display tells you both levels are alive before you commit.
Hardware in the loop
The producer's rig
MIDI out to the synth, MIDI in from the controller, a stereo pair back through the line inputs and four balanced outs to monitors and a headphone amp. The R4 is the hub, not the bottleneck.
Live, and unattended
Streaming and performance
AUTO gain rides the level while your hands are on an instrument. Direct monitoring means you hear yourself in time, not a beat late. Dual USB-C means the laptop is not also the power supply.
Why Layarav
A new brand has to earn it in the open.
We have no awards wall yet. What we have is a warranty, a support line in your time zone, and every number published.
3 years
Warranty, stated up front
Three years of hardware cover on every unit, printed on the product page rather than buried in a PDF. Register your serial and it activates.
India
Made-for-India support
Support and service run from here, in your time zone. Questions get a reply within one business day, not a ticket number and silence.
Published
Transparent engineering
110 dB dynamic range. −128 dB EIN. +9 dBu maximum input level. Every figure is in the specification table where you can hold it against anyone else’s.
LR4-01-0047
Serial-tracked authenticity
Every R4 carries a registered serial in the format LR4-{batch}-{sequence}. If it is not in the register, it is not ours.
The Raag Series
This is chapter one.
A raag is a framework — a set of notes and rules that a musician builds a performance inside. It is not a song. It is what makes a song possible.
The Raag Series is the same idea in hardware: a shared standard for conversion, build and support that every Layarav instrument is held to. The R4 is the first. It will not be the last.
