jd.Edit is a waveform editor for iPhone — cut audio like on a desktop. On top of that, the app records through USB audio interfaces in true stereo and remembers your input choice instead of letting iOS silently switch back to a Bluetooth headset. And it writes MP3 with its own encoder — something iOS cannot do at all — calibrated against the reference encoder LAME. FREE — INCLUDED FOR EVERYONE • Opens WAV, AIFF, CAF, MP3, M4A/AAC, Apple Lossless, FLAC and Opus (mono and stereo) • Waveform with two-finger zoom all the way down to individual wave cycles • Select, listen, delete, trim to selection, silence — non-destructive, with unlimited undo; the original file is never touched • Linear fade-in and fade-out • Zero-crossing snap and a 2 ms micro-fade at every cut edge: no clicks • Recording with the built-in microphone as uncompressed WAV (44.1 kHz / 24-bit) • File shelf with folders, search, preview playback and mini player — visible in the iOS Files app • Export as WAV and AAC. At the same bitrate, AAC actually beats MP3 in quality — the free tier does not get the worse result, just not the older format The free tier is deliberately complete: if you trim a voice memo or cut a ringtone, you will never hit a wall. THE PRO UNLOCK — ONE-TIME PURCHASE, NO SUBSCRIPTION • MP3 export with the built-in encoder jd.Codec: constant bitrate, variable (V0–V9) or average bitrate, joint stereo, sample-accurate gapless • Freely shapeable fade curves with seven presets — drag, add and remove points, with dB and time readout • Normalize to peak level or loudness (RMS) with a selectable target and clipping protection • Recording through USB audio interfaces and in stereo — with a real-time spectrum analyzer and level meters • Wi-Fi transfer: upload and download files in a browser on your computer, with QR code and access code; hotspot mode gets around hotel and guest networks • Export in 24-bit and 32-bit float, with dither • Edit ID tags on MP3s: title, artist, album, cover and more — in the app and in the browser on your computer via Wi-Fi transfer And nobody buys blind: every Pro feature can be used five times for free — only then does the app ask for the purchase. ABOUT JD.CODEC iOS ships without an MP3 encoder — jd.Edit brings its own. jd.Codec is developed entirely in-house with zero third-party libraries, verified with 116 round-trip checks against Apple's own decoder and benchmarked against LAME. And lossless is always available: import → export without edits is bit-identical for WAV.
