Your rig
A guitar amp + speaker cabinet (or a combo) making sound in the room.
Capture your real amp & cabinet as an impulse response — with just your phone. Load it into any DAW, plugin, or modeler.
User Guide · Capture your first IRCabPrint plays an exponential sine sweep through your rig, records what the speaker actually sounds like, and uses FFT deconvolution to recover a clean impulse response — a .wav snapshot of your cab's tone you can use anywhere.
Point the phone's mic at the speaker cone, about 10–30 cm (4–12 in) away — dead-center on the cone is bright and aggressive, toward the edge is warmer and darker. Prop it steady so it can't move during the sweep.
Open Capture. The defaults are good for most rigs, but you can set SWEEP LENGTH and IR LENGTH, and leave Low-cut (DC block) on to keep the low end tight. Turn the amp up to a normal playing volume — loud enough to clearly beat the room, not so loud it distorts the phone mic.
Press the big CAPTURE button. You'll hear a 2–5 second sweep and see SWEEPING % climb, then WORKING… while it deconvolves. Don't talk or make noise until it finishes — the room is being recorded too.
You'll land on the captured IR showing its Impulse Response waveform and Frequency Response curve. A smooth curve that looks like your cab's voice = a good capture. Tap to Rename it something you'll recognize (e.g. "4x12 V30 edge").
Leave it dry (the raw cab IR) or open the Mic Locker and Choose a mic character. Fine-tune with Cone ↔ Cap, On-axis ↔ Off-axis, and Close ↔ Far. Hit Audition to hear a guitar played through it, then Export 24-bit WAV → save to Files, AirDrop, or Share.
12 mic characters — ribbon, dynamic, tube, and FET — each with a real voicing you can layer over your captured cab. Pick by the sound you want, then shape it with the tweak sliders. Names describe the character, not any brand.
