AudioRecorder turns your iPhone or iPad into a clean, no-nonsense recorder for your USB audio interface - in the studio, at home, or on stage. Plug in your interface, choose your inputs, and capture uncompressed 24-bit WAV at your hardware's native sample rate. No conversion, no color - just your signal. Built for musicians and home studios who want a dependable capture tool without launching a full DAW. RECORD • Works with any class-compliant USB audio interface • Uncompressed 24-bit PCM WAV at the interface's native sample rate - never resampled • Mono, stereo, or mono-sum capture • Choose exactly which inputs feed Left and Right, so a multi-input interface lets you pick any two • Live level meters with a peak readout and clip indicator for dialing in gain • Preview the input before you commit to a take • A big, unmissable record button and elapsed timer STAY IN CONTROL • Live "time remaining" estimate from your free space, with a low-space warning • The screen stays awake while recording, so the meters never dim • Interrupted takes - a phone call, an unplugged cable - are saved as partial recordings, not lost LIBRARY • Play back with scrubbing • Rename, delete and organize your takes • Share via AirDrop or Files, or export straight to a USB drive SETUP HELP • A built-in connection guide shows exactly how to wire things up, with diagrams for both USB-C and Lightning devices WHAT YOU NEED • A class-compliant USB audio interface • If your iPhone or iPad has a USB-C port, then the Audio Interface will work without external power • On Lightning devices, an Apple Lightning to USB Camera Adapter is needed and the Audio interface needs a source of external power AudioRecorder does one thing and does it cleanly: get the signal from your interface onto your device, uncompressed and intact.
