Real Time True-Peak limiter

ISL 2st is a transparent look-ahead limiter designed to allow you to get on with creative audio production while it takes care of True Peak compliance for you.

ISL 2st uses the standardised True Peak algorithms of ITU-R B.S. 1770 and related standards (including Apple ‘afclip’ True Peak detection), and is suitable for the control of audio for post production, music mastering and broadcast applications. True Peak limiting can also be used to ensure that downstream codecs (mp3, AAC etc.) do not introduce distortion into the signal.
