Limiter

The limiter restricts the input signal level by compressing its dynamic range above a specified threshold. The limiter is most commonly used to prevent clipping, protecting a system against component or speaker damage. While the limiter is closely related to the compressor, it applies a much higher compression ratio of ∞:1 above the threshold. The ratio is fixed and cannot be changed. Click in each field to change the value.

Threshold — The input signal level above which limiting begins (subject to attack time) and below which compression stops (subject to hold and release time).

Threshold level can be adjusted from – 80.0 to 0.0 dB in 0.1 dB increments.

Default is –10.0 dB.

Attack Time — Adjusts the time delay for limiting to engage after the input signal level reaches or exceeds the threshold level.

Attack time can be adjusted from 0.0 to

200.0ms in 0.1 ms increments. Default is 2.0 ms.

Hold Time — Adjusts how long limiting continues after the input signal drops below the threshold and before release time begins.

Hold time can be adjusted from 0.0 to

500.0ms in 0.1 ms increments. Default is 50.0 ms.

Release Time — Adjusts the time it takes to return the signal to normal (unprocessed) levels after the signal no longer exceeds the threshold level setting. Release time begins only after hold time is reached.

Release time can be adjusted from 10 to 1000.0 ms in 0.1 ms increments. Default is 50.0 ms.

Soft Knee — Select the Soft Knee checkbox to smooth and soften the transition from uncompressed to compressed output levels. There are no adjustments.
