Sonalksis has released CQ1 Multi-Band Compander and DQ1 Dynamic Equaliser for Windows (VST/DX) and Mac OS X (VST/AU).

CQ1 Multi-Band Compander

CQ1 is a multi-band frequency-selective dynamics processor, allowing independent compression or expansion of four freely adjustable filter bands. Unlike typical multi-band compressors that are designed primarily to master composite program material, the CQ1 uses the principle of 'dynamic equalisation' and is therefore suitable for a much broader range of applications.

The 'frequency selective' processing employed by the CQ1 is far more sophisticated than standard 'frequency conscious' multi-band compression. The CQ1 greatly extends the possibilities of dynamics processors with the ability to refine specific frequency compression or expansion with unparalleled accuracy. Although it uses the same dynamic-EQ principle as the DQ1, the CQ1 is designed primarily to provide gentle or aggressive shaping of the signal dynamics in explicit frequency bands, rather than the subtle frequency sculpting of the DQ1.

In addition to general program compression/expansion, the CQ1 will find uses in applications that may otherwise present difficulties for less flexible processors, including Multi-source separation, High/Low frequency enhancement, Transient enhancement and De-essing or Pop/Squeak reduction.

Features:

• 4 independent bands of sophisticated yet intuitive frequency-selective compression or expansion.
• Selectable above or below threshold (upwards or downwards) operation.
• Sonalksis 'State-space' physical model ensures 'true analogue' response.
• Definable side-chain filtering ensures any frequency can act as a trigger.
• Zero latency: absolutely no internal delay whatsoever.
• 64bit floating point internal precision throughout.
• Ultra efficient processing, with specific optimisations for native processors.
• Up to 192 kHz support.

DQ1 Dynamic Equaliser

The DQ1 dynamic-equaliser is a versatile processing tool that can be used for precision sculpting, creative moulding, ambient enhancement or restoration.

Dynamic equalisation allows frequency sculpting beyond the limits of standard 'static' equalisers, by linking the user-defined frequency response to the audio signal level; thus frequency imbalances can be corrected psychacoustically, altering an equalisation curve dynamically on the basis of programme loudness. This makes the DQ1 extremely flexible and suitable for a variety of sound design roles, working as a perfect compliment alongside the Sonalksis SV-517 multi-style (static) EQ.

The DQ1 is a frequency sculpting processor first and foremost, appropriate more for dynamic-filtering purposes than frequency-selective dynamics, and although these two applications are to some extent interchangeable, the DQ1 will be more at home as a tool to provide gentle but precise sculpting of the audio spectrum.

Features:

• 4 independent bands of sophisticated yet intuitive dynamic filter control.
• High quality minimum phase 'true analogue' filters using Sonalksis 'State-space' physical model.
• Zero latency: absolutely no internal delay whatsoever.
• Each band is switchable between dynamic or standard 'static' mode.
• 64bit floating point internal precision throughout.
• Ultra efficient processing, with specific optimisations for native processors.
• Up to 192 kHz support.

CQ1 and DQ1 each cost 279.99 USD / 229.99 EUR / 159.99 GBP, or can be purchased together for 449.99 USDS / 359.99 EUR / 249.99 GBP. Demo versions are available.
