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.
Raag Series · LA-R4
A 4-in / 4-out USB-C audio interface with pro I/O, ADAT expansion, and studio-grade conversion — built for creators.

Why we exist
Precision and feeling are not opposites. We build audio hardware in India, measured to a standard and tuned to an ear — for the people making music here.
लय — laya, rhythm.रव — rav, sound. Layarav is both, because neither one is music on its own.
The R4
The Raag Series begins with an interface that competes on hardware — the part you cannot download later.

Sur · The preamps
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.

Nāda · The conversion
Nāda is the primordial sound — the thing that exists before it is shaped. Our conversion stage is built to add nothing to it.

Vistār · The expansion
In a raga, the vistār is the slow unfolding — the section where a form grows into its full size. The R4 has an ADAT optical input, which means the four inputs you bought are not the four inputs you are stuck with.

Two voices, one room
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
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
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
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
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
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
110 dB dynamic range. −128 dB EIN. +16.2 dBu of headroom. Every figure is in the specification table where you can hold it against anyone else’s.
LR4-01-0047
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
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.
