A transparent look-ahead limiter that ensures True Peak compliance for music mastering, post production and broadcast.

ISL 2 uses the standardised True Peak algorithms of ITU-R BS.1770, including Apple afclip detection, preventing the inter-sample peaks that would otherwise cause distortion when audio is later converted to MP3 or AAC. Its TPlim control automatically adjusts the transfer curve for minimally invasive brick-wall protection, while auto-release monitors low-frequency content and adapts dynamically. Steering and ducking meters guide you to the right settings, whether you are preserving directional integrity or atmospheric ambience. With support up to 7.1.4, ISL 2 suits mastering for streaming services as well as broadcast and film production.
