Record

The Record area turns the iPhone into a recorder: uncompressed WAV at 44.1 kHz / 24-bit — source material without compromise.

✓Free choice of input: built-in microphone, headset, Bluetooth — and USB audio interfaces in true stereo
✓Your input choice is remembered; iOS may not silently switch back to a headset
✓Monitor with real-time spectrum (50 Hz–16 kHz), L/R level meters and clip indicator
✓Recordings land in the file shelf immediately, ready to edit

Edit

The core of the app: one waveform, precise cuts — like a desktop sample editor, designed for the touchscreen.

✓Two-finger zoom all the way down to individual wave cycles, fluid thanks to a peak pyramid
✓Selection mode via double tap: draw a range, listen, delete, trim, silence
✓No clicks: zero-crossing snap and a 2 ms micro-fade at every cut edge
✓Freely shapeable fade curves with seven presets — drag, add, remove points
✓Normalize to peak or loudness (RMS) with upfront measurement and clipping protection
✓Non-destructive with unlimited undo — the original file is never touched

Export with its own MP3 encoder

WAV, AIFF, CAF, Apple Lossless, AAC — and MP3 via jd.Codec, the in-house encoder calibrated against LAME that iOS itself doesn't ship: CBR, VBR (V0–V9), ABR, joint stereo, sample-accurate gapless. Bit depth and dither of your choice, size estimate before writing, “Compress” right from the file list.
