SiliconIntervention Announces Availability of Silicon-Based Fractal-D Audio Amplifier Evaluation Board

SiliconIntervention announced the availability of an evaluation board, demonstrating the high efficiency operation of its Fractal-D audio amplifier aimed at wearable applications such as earbuds and smart glasses as well as mobile products that demand extended battery life. SiliconIntervention is the company exploring a new type of bridge configuration that improves the efficiency at lower power levels while maximizing efficiency over a wide range of power levels.

ROHM has developed a 32-bit D/A converter (DAC) IC and an evaluation board for flagship models in its MUS-IC series, optimized for high-resolution audio playback. Specifications detail top-class THD+N and signal to noise rations, working from 32kHz to 1536kHz PCM sampling frequencies or DSD native signals. The new DAC is touted by the Japanese manufacturer as able to deliver a more authentic listening experience by better expressing spatial reverberation, quietness, and dynamic range while preserving the natural “texture" of musical instruments.

HEAD acoustics announced Release 16.5 for its ArtemiS sound and vibration measurement and analysis software Suite. Highlights in the software update include Reference+, a new automated structural analysis module that uses a Neural Network with advanced algorithms, support for quick shaker measurements with the Recorder, and SQala Lite, a new entry-level solution for objective listening tests. There are also many user interface and usability improvements and features in the update.
