Sonic Anomaly just released Unlimited, a freeware mastering limiter in 32-bit and 64-bit VST plugin format for Windows-based digital audio workstations.
Unlimited is a high-quality maximizer/limiter effect that supports stereo and 5.1 surround audio material developed by Sonic Anomaly.
The plugin features RMS meters and an ITU-R BS.1770 compliant loudness meter for monitoring the signal loudness on the output. It automatically adjusts to the type of audio signal on the input, reducing the overall CPU hit if a stereo signal is detected.
The user interface (designed by Crimson Merry) looks fantastic and features an intuitive control scheme. The two main controls, “Threshold” and “Out” are positioned on the left side on the interface, next to the RMS and LUFS meters.
When working with a 5.1 surround signal, the “Threshold” control on the left is customizable using the three “Weight” controls on the right (Center, LFE, Surround). These three sliders control the threshold offset amount for the center, low-frequency effects (LFE), and surround channels.
The “Character” slider determines the aggressiveness of the limiting algorithm, emphasizing transients at lower values. Increasing the value will result in less distortion and less prominent transients. The “Response” slider can be used to apply a more compressor-like type of gain reduction to the signal, although the high peaks will still be hard limited.
The “Classic Mode” switch will change the plugin’s default behavior to a classic limiter instead of a maximizer.
Compared to Sonic Anomaly’s older releases, Unlimited uses a more flexible coding language which should ensure compatibility with a much larger number of digital audio workstations and audio editors. The same can be said about the recently updated Transpire transient shaper and Bass Professor MK2 plugins.
The plugin is available for direct free download from the developer’s website, no registration or activation required. It works as a 32-bit and 64-bit VST plugin in compatible digital audio workstations on Windows.
