Sir Elliot has released a free peak limiter plug-in for Windows, branded Peak Limiter.
Here's what Sir Elliot has to say about Peak Limiter:
This is a very simplistic yet useful Peak Limiter. As the name implies it’s sole purpose is to prevent overshoot, which is common with high dynamic music without the artefacts of a compressor.
Power Consumption is under 1% on a Pentium 4, 2.8 GHZ CPU in addition to managing 384 kHz sample rate files with no issues whatsoever.
