ISL 2st is a True Peak limiter dedicated to respecting true peak levels at the end of the chain. It ensures loudness compliance without compromising dynamics or spatialization, avoiding distortions caused by inter-sample reconstructions and lossy encodings (AAC, MP3). Ideal on the master bus for music, audio for picture, podcasts, and broadcasting, it guarantees reliable translation on online services and on-air.
The core of ISL 2st relies on standardized True Peak algorithms (ITU-R BS.1770-4) with a brick-wall mode driven by the TPlim control and musical look-ahead. The ceiling remains inviolable while preserving clarity, including on bass-rich stereo signals.
Steering and ducking indicators guide your settings to maintain directional integrity or ambiance. Apple "afclip" monitoring detects inter-sample peaks that may appear after conversion, anticipating any distortion.
The auto-release analyzes the content (notably low frequencies) and automatically adapts the release to maintain maximum transparency, even in demanding situations. You mix and master with confidence for platforms like Apple Music, Spotify, or Tidal.
Designed for post and broadcast, ISL 2st facilitates meeting broadcasters' True Peak criteria while offering broadcast-class quality. The Loudness Toolkit suite from the developer, of which ISL is a central element, is recognized in the professional ecosystem, ensuring reliable signal flow.
