Nye multifunktionelle lydprocessorer

ROHM lancerer en ny serie af multifunktionelle soundprocessorer til home og car audio systemer (in english). 

Semiconductor manufacturer ROHM has announced the development of eighteen different sound processors optimized for today’s increasingly sophisticated car- and home-audio systems.

The greater number of inputs and outputs required to accommodate multiple audio sources and speakers for higher fidelity playback, coupled with the need for fine-tuning of the characteristics to match the acoustic effects of the particular environment, have created a demand for high performance, multifunctional sound processors.

In order to meet these various needs, ROHM offers a complete line-up of eighteen different types of sound processor ICs in a variety of input source channels, speaker outputs, and acoustic correction functions. Features include low distortion and low noise – factors essential to high fidelity audio – along with advanced switching functionality that reduces unpleasant switching shock sounds by smoothing discontinuous waveforms generated during volume switching.

In addition, models are available that integrate acoustic correction functions, including parametric equalizers, loudness circuits, and subwoofer LPF/HPFs that allow optimized audio playback based on vehicle cabin characteristics. A common register map is also included in all models, allowing simple control from most existing microcontroller software, and upgrading performance is as easy as changing the sound processor.
