ISL 2st is NUGEN Audio's True Peak limiter for mono and stereo material: a transparent, look-ahead brick wall that sits at the end of the chain and makes sure nothing clips once your track has been converted to MP3 or AAC. It's the stereo edition of ISL, the limiter used in broadcast and post, packaged for music mastering.

NUGEN Audio ISL 2st True Peak limiter plugin interface

Why True Peak matters

A sample-peak limiter set to -0.1 dBFS can still produce overs. The waveform between the samples can swing higher than the samples themselves, and lossy codecs make it worse. ISL uses the standardised True Peak detection of ITU-R BS.1770, plus Apple's afclip measurement, so the ceiling you set is the ceiling you get after encoding, not just inside your DAW.

How it behaves

Rather than a traditional threshold, ISL has a TPlim control: set the True Peak limit and it adjusts the transfer curve for the least invasive limiting that will hold it. Auto-release watches the low end and adapts to stop bass-heavy material distorting, and the steering and ducking meters show exactly how hard it's working and where. The result is clean, honest peak control rather than a loudness maximiser with a character of its own.

Where it fits

Last plugin on the master bus, after your main limiter or as the only one on a dynamic master. It's just the ticket for streaming delivery, podcasts and anything that has to pass a technical spec. If you want colour and density, use something else first and let ISL guard the door.
