pegelWERK easy EDITOR is a focused audio cutter for radio, podcast and post-production work — built around two standout features: broadcast-grade EBU R128 loudness normalisation, and a seamless round-trip pairing with its companion app pegelWERK instant PLAYER. Open any audio file from the Files app, trim to the section you want, normalise to EBU R128 (-23 LUFS) with inter-sample peak protection, and export a clean 24-bit WAV — all on iPhone or iPad, all on-device. EBU R128 NORMALISATION — BROADCAST-GRADE, IN YOUR POCKET Tap the R128 toggle, hit EXPORT, and easy EDITOR delivers a file that meets EBU R128 / ITU-R BS.1770-4 loudness targets — exactly -23 LUFS Integrated, with true-peak headroom verified against 4x oversampling. The processing chain measures the source, applies static gain to land on target, then runs the audio through a look-ahead true-peak limiter so no inter-sample peak exceeds -1 dBTP. A second refine pass corrects the residual offset the limiter introduces, so the final file lands exactly on target — not "close enough". This is the same loudness pipeline broadcast engineers run on dedicated hardware, on a phone you already own, without a subscription. WORKS WITH pegelWERK INSTANT PLAYER — ONE-TAP ROUND-TRIP easy EDITOR and pegelWERK instant PLAYER are designed as a pair. While a live show is loaded in instant PLAYER, tap CHOOSE there, pick the pad you want to clean up, and the audio lands here in easy EDITOR in one step. Trim the silence, set sample-accurate IN / OUT handles, normalise to -23 LUFS — then tap SEND BACK. instant PLAYER springs to the foreground and drops the edited audio straight back into the same pad, cue point and colour preserved. No exporting, no file-juggling, no broken takes. Cleaning up a cue takes seconds and the show file stays the single source of truth. KEY FEATURES • Open WAV, MP3, M4A, FLAC, AIFF, OGG from Files / iCloud / On My Device / AirDrop. • Visual trim with PLAY IN / PLAY OUT preview, zoom to in / out for sample-accurate cuts. • Tape-style continuous scrub at the IN / OUT handles for fine positioning by ear. • EBU R128 loudness normalisation with true-peak limiter (4× oversampling polyphase). Two-pass refinement lands you exactly on -23 LUFS without clipping above -1 dBTP. • Background-thread render so the UI stays responsive on long files. • Export WAV at 24-bit, native sample rate, with metadata preserved. • Save and reload entire editing sessions as portable .pwedit bundles (audio + selection + history). • Universal — iPhone (portrait + landscape) and iPad (all four orientations). • Dark interface tuned for studio use. No ads, no analytics, no account. PRIVACY easy EDITOR does not contact any server, does not collect personal data, and does not include any third-party SDKs. The audio you open stays on your device unless you explicitly export it. SUPPORT More pegelWERK apps and contact: pegelwerk.com
