World class, broadcast quality limiting is an essential requirement for any audio production, and the latest standards also demand true-peak compliance. ISL 2st delivers both, giving you superb sound with complete confidence about meeting the new standards for online delivery. ISL 2st is an intelligent look-ahead brick-wall limiter that provides highly transparent True Peak limiting for all stereo & mono content. ISL 2st is designed to allow you to get on with creative audio production while it takes care of true-peak compliance for you. It delivers content fully compatible with loudness normalization standards used by iTunes Radio, Spotify and many others. The risk of distortion from down-stream codec conversion (mp3, AAC etc.) is eliminated with ISL 2 on the master bus. No need to second guess your sample-peak limiter time and again, or deliberately increase headroom to avoid a downstream problem. Just dial in your true-peak limit and let ISL take care of the rest. Pristine Quality True-Peak Limiting ISL 2st includes Apple ‘Mastered for iTunes’ true-peak detection, and many other algorithms suitable for the control of audio for Music & Post Production applications. Powerful Processing and Visualisations With unique Steering and Ducking meters, ISL2st guides you to the perfect settings. Whether you are preserving directional integrity or atmospheric ambience, ISL2st gives you the information and control you need to achieve your objective with ease. New processing enhancements assess the incoming audio for frequency content and automatically take care of those minor adjustments required when LF content drives the limiter, delivering increased transparency whilst maintaining our renowned reputation of intuitive operation.
