FinalPlugAAXDSPbrings our professional peak limiter to yourHDXDSPsystem. FinalPlug is a lookahead peak limiter/volume maximizer featuring very low latency, transparent operation, and extensive bit depth truncation and dither options, making it ideally suited for a final mix. Tame the peaks a bit, or really squeeze all the volume you can out of it.

The FinalPlug interface could hardly be simpler. Select a desired output ceiling level, say -0.1 dB, and then adjust the threshold level. As you decrease the threshold you increase the volume.

The peak limiter section works by looking ahead 1.5 milliseconds. When a input peak is detected that will exceed the desired output ceiling, the gain is quickly ducked to let the peak pass, then the gain is restored relatively slowly according to the release time control. During rapidly changing program material with frequent peaks, a faster release time will achieve better results. During slowly changing material, slower release times prevent excessive modulation distortion. FinalPlug’s auto release feature analyzes the input signal to determine peakiness, and selects the optimum release time for the program material.

The truncate/dither section is usually used for CD mastering, where truncation to 16 bits can create audible quantization distortion. By adding special dither noise, the quantization distortion can be eliminated, and the dither noise can be spectrally shaped to move it to frequency ranges where it is less audible. FinalPlug contains a comprehensive noise shaping section which reproduces a variety of commonly used noise shapes.

In order to maximize yourDSPinstance counts, FinalPlugAAXDSPcomes with two configurations. The full configuration provides all features, while the Limit configuration provides just the limiter section. At 48 kHz, you can run 4 stereo instances of the full configuration, and 17 stereo instances of the Limit only configuration.
