loudness CORRECT measures, corrects and verifies your audio to any broadcast or streaming loudness spec — fully offline, on iPad and iPhone. Pick a file, pick a preset, correct. The two-pass pipeline measures the source to ITU-R BS.1770-4, plans the gain move, writes a new file and re-verifies the result — so what leaves the app is provably on target, not just close. WHY IT'S DIFFERENT • Verified output: auto-verify and refine until the residual error is under 0.1 LU. No guessing, no manual re-check. • Transparent loudness range control: a continuous 3-band reshape (Linkwitz-Riley) works toward the programme level — it tightens loud passages and lifts quiet ones with no threshold and no pumping. • True-peak safe: 4× oversampled inter-sample peak limiter with 5 ms look-ahead keeps you under the ceiling on every platform. 14 DELIVERY PRESETS EBU R128, EBU R128 S1, ATSC A/85, ARIB TR-B32, AGCOM 219/09, FreeTV OP-59, DPP UK, Portaria 354, OTT -27 LUFS, Apple Podcasts, Spotify, Amazon Music, YouTube, and a fully editable Custom preset. MULTICHANNEL From mono and stereo through 5.1 and 7.1 up to 9.1.6 Atmos bed layouts — BS.1770-correct per layout, with LFE exclude and proper surround weighting. FORMATS Input: WAV, AIFF, FLAC, OGG, MP3, M4A Output: WAV, AIFF, FLAC • K-weighted ITU-R BS.1770-4 measurement (integrated, range, true peak) • Dark, focused UI — German and English • No account, no login, no network calls — your files never leave your device MADE FOR Mastering engineers, broadcast and post editors, podcast and audiobook producers, sound designers — everyone who has to hit a delivery loudness target quickly, cleanly and provably.
