Those amazing minds at miniDSP never cease to surprise us. Now miniDSP has turned its attention to the headphone market and introduced "EARS", an Earphone Audio Response System calibrated test jig for headphone measurements. Basically, a plug&play USB audio streaming device, featuring dual low noise calibrated mics with interchangeable silicon ears. Add the new miniDSP HA-DSP DSP headphone amplifier, and users have an accurate way to tune headphones to perfection.

The new miniDSP UMA-8 is a high-performance yet low cost multichannel USB microphone array built around XMOS multicore technology, designed for voice-recognition application development. Seven high-performance MEMS microphones are configured in a circular arrangement to provide high-quality voice capture for a wide range of applications. Leveraging the onboard DSP processing, the UMA-8 supports voice algorithms including beamforming, noise reduction, acoustic echo cancellation and de-reverb.

miniDSP introduced the DDRC-24, a USB DAC+DSP Digital Room Correction processor powered by Dirac Live, featuring Toslink, analog inputs and up to 4 processed outputs for 2.0, 2.1, or 2-way active speaker configurations. With the smallest Dirac Live hardware processor miniDSP is making room correction even easier and more affordable, perfect for tuning hi-fi listening rooms, subwoofer integration, tuning mobile applications and adjusting monitors in recording studios.
