A 4-track field recorder in your pocket.

RECINDX turns an iPhone into a proper field recorder: four tracks, audio interface support, and a workflow that matches how location sound actually happens — REC the takes, INDX the keepers, MIX the balance, SEND the result.

RECINDX on iPhone: four track slots with meters and the REC – INDX – MIX – SEND workflow

RECINDX on iPhone — REC · INDX · MIX · SEND.

Built for location sound

Four real tracks

Record up to four tracks at once — ambience on one pair, spot mics on the rest. LINK pairs two channels into a stereo track.

Audio interface support

Plug in a USB interface and RECINDX picks up its channels directly — from a single mic preamp to a multichannel rig.

Index the keepers

Mark the good takes as they happen. When the session ends, the keepers are already sorted from the rest — no scrubbing through an hour of audio at the desk.

Mix on the device

Balance the tracks right on the phone — levels and pans — before anything leaves the field.

Send it anywhere

Export the mix or the individual tracks and send them onward — AirDrop, Files, or straight into your edit.

Part of the INDX family

Recordings made with RECINDX drop neatly into a SOUNDINDX library on the Mac — record in the field, index, then shape and deliver in the studio.

FREE BETA — HELP SHAPE IT

RECINDX is in active development and free to use through TestFlight while in beta. The feedback of working recordists decides what gets built next — tell us what confused you, what broke, and what you missed.
