Fiche technique
- Fabricant : Acustica Audio
- Modèle : Aquamarine3
- Catégorie : Compresseurs logiciels
- Fiche créée le : 02/08/2016
Updated version of the Mastering Compressor Plug-in modeled from the Murano Compressor and using the Core8 processing engine.
- The first compressor is a smooth and warm sounding Opto style compressor. Simple to use with just a threshold and gain make up, it is great at effortlessly controlling dynamic range and to and finesse the signal.
- The second compressor is a Discrete VCA style which is punchy and can really grab a signal.It can go from a subtle 1.2:1 ratio for gentle control and transient preserving compression, to a savage ‘Flood’ overlimit, to be used for creative compression effects. The Discrete VCA has controllable timings to suit many situations and with digital technology the attack time has been improved to reach almost zero with very low aliasing.
- The compressor section also features a high pass filter to control the compressors response to bass frequencies and a mix control which builds on the original unit’s functionality by providing onboard parallel compression without the complication of aux tracks.
- One of the exciting new features that is new to software is what we call “ShMod”. This is an adjustable shape control for the attack behavior of the Discrete compressor.
- Another innovative feature that also exponentially increases the versatility of this compressor is the Look-ahead. The input signal is split, and one side is delayed. The non-delayed signal is used to drive the compression of the delayed signal, which then appears at the output. This way a smooth-sounding slower attack rate can be used to catch transients.
Preamplifier section
The first processing stage is the preamp section, switchable with the PRE switch. Possible preamps are:
P-1: the same vintage preamp of PURPLE P-1, very clean.
Bronze: the most colored setting.
Silver: more colored than gold but quite clean.
Gold: with low distortion and flat low frequency response.
Opto section
The second stage is the Opto Compressor. This is an emulation of an optical attenuator. The controls for the Opto Compressor are Opto Threshold and Opto Gain.
Opto Threshold: controls level above which the compressor considers the signal too loud engaging compression, Aquamarine loads with a 0dB threshold.
Opto Gain: controls the amount of makeup gain, which is used to restore the compressed signal to the desired amplitude.
Opto: section is engaged by Opto Bypass In/Out switch.
Opto ahead: this control is Program-dependent, it means that rather than responding to a fixed value, the attack time is variable based on the input signal.
Look-ahead goes from 0 to 4 ms.
The input signal is split, and one side is delayed. The non-delayed signal is used to drive the compression of the delayed signal, which then appears at the output. This way a smooth-sounding slower attack rate can be used to catch transients.
Discrete section
The third stage is the Discrete Compressor, that emulates a VCA. The controls are similar to the optical section with some additional knobs: discrete ratio, discrete attack and discrete recover.
Discrete section: is engaged by Discrete Bypass In/Out switch.
Discrete ratio: has six positions and determine the ratio of the compressed signal. The first position corresponds to a ratio of 1.2:1, so one additional decibel above the threshold produced. Available values are 1.2:1, 2:1, 3:1, 4:1,6:1 and FLOOD with 20:1 ratio.
Discrete attack: varies how fast or slow the compressor engages once the compression threshold has been reached.
All attack values respond to fixed values.
Discrete recover: determines how long it takes the signal to return to the uncompressed level after the signal level falls below the set threshold. All recover settings respond to fixed values (single release) except for "DUAL" position (AUTO-RELEASE).
Discrete section: is engaged by Discrete Bypass In/Out switch.
Discrete SH-MODE: ShMod control is an adjustable shape control for the attack behavior of the Discrete compressor.
The Default position is 2, it's the "normal" Aquamarine3 attack (0ms of look-ahead). You can go down till 0 reaching up to 4ms of look-ahead. On the other side you can reach gradually position 4 to dramatically change the shape of the attack.
Side-chain switch
The side-chain filter engages a filter in the side-chain of both the opto and discrete sections, which cuts off frequencies below 90Hz that will not trigger the onset of compression.
Meters
Depending on the currently active program on METER TYPE switch, meters may vary their output information;
Opto Discrete led on: meters display the reduction levels of opto (left meter) and discrete (right meter) compressors;
Input-Output: meters display the input (left meter) and output (right meter) levels of the plug-in
Mix
The MIX knob weighs the original signal percentage in the final mix. With 0% the input signal is completely clean, while with 100% its completely processed.
Input Trim
This knob sets the input level from -24dB to +24dB, and is used to control the signal level inside the compression chain; the output level is than automatically compensated by the same amount of gain. At the first execution of the plug-in, input is set to ensure that you feed an appropriate level from the first stage of your signal path to the final one.
Output Knob
This knob sets the input level from -192dB to +6dB.
