Dynamic gain reduction can achieved by increasing the INPUT GAIN sufficiently for the internal signal to surpass the 0 dBFS reference level.

The processing threshold is set to 0 dBFS by default. When the ENHANCE control is disabled in Normal Mode (at 0% with SAFE MODE disabled), the Pre-Process section can be used as a conventional levelling section in its own right. Its primary purpose is to control programme level over a wide range, in order to create optimum conditions for the following enhancement stage. The Pre-Process section provides a musical programme levelling function. In this mode the ENHANCE control varies the perceived loudness boost of the programme by modifying the processing law. at 0% setting), in which case the Pre-Process section may be used as a conventional programme levelling application if desired.Ī SAFE MODE is provided which uses the enhance processing to permanently control peak levels. A variable control allows the enhance process to be adjusted or removed completely (i.e. The normal ENHANCE control setting for this action to fully occur is 100% and above in Normal Mode, (or any enhance setting with SAFE MODE selected). These processes are used in conjunction to enable the sound of transient and dynamic information within your programme material to reach the output of the plug-in, despite very tight control of maximum peak sample values. In order to achieve this, the application employs gain scaling and compression in the Pre-Process section, and peak overshoot control in the enhancement section. The primary purpose of the plug-in is to control peak levels and increase the volume, density and presence of musical programme without an excessive loss of transient and dynamic information that normally results from conventional peak limiting applications. Reconstruction metering and compensation.

Programme enhancement and overshoot control.

The Limiter plug-in is comprised of four processes, cascaded in the following order: Unique processing in the form of the Enhance function provides the sample value limiting needed to reliably avoid overloads in digital workstation environments, and allows unprecedented volume and punch to be applied to programme beyond that available from conventional limiting functions.Ĭomprehensive metering is included, which displays not only conventional peak sample value, but additionally allows the user to monitor the true validity of the programme in order to avoid the generation of damaging reconstruction overloads in the target equipment, which are often invisible during production (sometimes termed ‘inter sample peaks’).Ī further function allows the user to dynamically correct for reconstruction overloads in real time, thereby achieving maximum possible modulation levels without the risks of producing ‘illegal’ signals often associated with compression and limiting.Ĭomprehensive dithering functionality is included, with selectable and variable depth noise shaping, which ensures first class mastering output quality in either 24 bit or 16 bit modes. By employing highly accurate logarithmic side-chain processing, along with innovative adaptive timing functionality using look-ahead signal acquisition, the Limiter offers exemplary performance, whether one is seeking general transparent level control, programme loudness maximisation or heavily applied artistic audio effects.

The Oxford Limiter plug-in has been developed from decades of professional audio experience to provide a very high degree of quality and capability in programme loudness control and limiting functions.
