HARVEY® ensures standard-compliant loudness in broadcasting operation

With the implementation of the Continuous Loudness Controller (CLC) in its own audio DSP HARVEY®, DSPECIALISTS GmbH offers a powerful system for high-quality loudness control.

The CLC processor (Continuous Loudness Control) allows the continuous adjustment of audio material to a predefined target value and a definable loudness range value with the lowest possible artefacts in real time. In this way, unpleasant loudness jumps in the programme can be avoided, but speech intelligibility can also be improved.

DSPECIALISTS, already known in the broadcast market for its high-quality ISOSTEM stereo-to-5.1 upmixer, has implemented this loudness control method in its HARVEY® audio DSP, thus expanding the HARVEY product family.


Dr. Jochen Cronemeyer, DSPECIALISTS Managing Director, says: "We are convinced of the high quality of the CLC algorithm and are very pleased to offer the CLC software in a stand-alone unit, thus expanding the application possibilities of HARVEY. In the first step, the processing of stereo signals with HARVEY® has been made possible, followed at a later stage by the extension to the 5.1 format." HARVEY CLC is equipped with an AES 8x8 interface, various clock options, bypass relays as well as redundant power supplies. 

As a freely programmable audio DSP offering numerous control interfaces, HARVEY® has been developed over the past years for fixed installations. Due to the high audio quality and the extensive software library for audio signal processing, HARVEY® is also ideally suited for use in studios. Analogue inputs and outputs as well as AES and Dante are available as audio interfaces. HARVEY® also offers the customer numerous control options. In addition to TCP/IP, RS485 and RS232, GPIOs can also be freely programmed. This allows HARVEY® to call up the optimal setup for every conceivable scenario and to communicate with other devices in the studio. DSPECIALISTS will present HARVEY® at the upcoming Prolight + Sound (Hall 11.0 Stand A46) in April in Frankfurt/Main.
