pegelWERK loudness CORRECT

pegelWERK loudness CORRECT is an offline loudness corrector for professional audio workflows, conforming to EBU R128 and ITU-R BS.1770-4.

Drop a file, pick a preset, correct. The two-pass pipeline measures the source, plans the correction, writes a new file and re-verifies the output.

Features:
• 16 delivery presets (EBU R128, EBU R128 S1, ATSC A/85, ARIB TR-B32, AGCOM 219/09, FreeTV OP-59, DPP UK, Portaria 354, Netflix, Apple Podcasts, Spotify, Amazon Music, YouTube, Leq(m) Cinema, Leq(a) Cinema, Custom)
• K-weighted ITU-R BS.1770-4 loudness measurement
• 4× oversampled true-peak limiter (ISP, 5 ms look-ahead)
• 3-band LRA reshape (Linkwitz-Riley bands, continuous gain function toward programme level — compresses loud and expands quiet passages, no threshold and no pumping)
• Auto verify + refine (residual error under 0.1 LU)
• Multi-channel 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 surround weighting)
• Input: WAV / AIFF / FLAC / OGG / MP3 / M4A
• Output: WAV / AIFF / FLAC

For mastering engineers, broadcast editors, podcast producers, sound designers and everyone who has to hit delivery loudness specs quickly and cleanly.
