miniDSP High-Performance USB Mic Array Now Shipping

The Multi-Application UMA-8-SP is a Fully Compliant UAC2 Audio Interface with Driverless Support

for Mac/Linux and ASIO Drivers for Windows; Designed to Provide High-Quality Voice Capture in

Farfield Microphone Applications Such as AI Assistants, Conferencing, Robotics, Etc.


HONG KONG, August 7, 2018 – miniDSP(, a market leading designer and manufacturer of digital signal processing platforms and solutions for a wide range of applications, is proud to announce that the new UMA-8-SP high-performance USB microphone array is now shipping. With an MSRP of $125.00 USD, the UMA-8-SP is a fully compliant UAC2 audio interface with driverless support for Mac/Linux and ASIO drivers for Windows.

“Our UMA-8-SP microphone array plus stereo Class D amplifier with onboard direction detection, echo cancellation, and noise reduction, has a wide array of applications,” explained Tony Rouget, miniDSP CEO. “Seven high-performance MEMS microphones are configured in a circular arrangement to provide high-quality voice capture in farfield microphone applications such as AI assistants, conferencing, robotics, and more.”

Leveraging the onboard DSP processing from XMOS XVSM3000, the UMA-8-SP supports voice algorithms including beamforming, noise reduction, acoustic echo cancellation, and de-reverb. An onboard 2x15Wrms digital amplifier provides an all-in-one microphone array plus amplifier integration.

USB audio capabilities include recording in two possible modes depending on firmware, such as 8-channel mode (7 x MEMS installed + 1 x spare PDM port in the center) and stereo recording with DSP processing enabled, as well as stereo channel to digital audio amplifier for USB audio playback.

“From DIYers to OEM, this pocket-size platform is engineered for flexibility in firmware, software, and hardware,” Rouget continued. “miniDSP’s website provides numerous applications, advice, step-by-step instructions, and methods for utilizing the UMA-8-SP microphone array for Google SDK, Alexa, Siri, IBM Watson, Micorsoft Cortana, and Matlab, with more to come in the near future.”

HEARS side by side

Introducing "EARS", the Earphone Audio Response System. miniDSP EARS brings headphone measurement capability to "the masses" - it's just an extremely affordable measurement rig for headphones and IEMs that we've built using the same technology as our popular UMIK-1 calibrated measurement microphone. Alternatively one could use EARS as a binaural microphone with USB audio streaming.

Each pair of EARS has two microphone capsules mounted in a minimal "dummy head". Measurement output is via the driverless USB connection. The EARS are powered from the USB so there is no need for an external power supply. To measure headphones, just mount your headphones on the rig and run a measurement sweep using your headphone amp and favorite measurement program (e.g. Room EQ Wizard). The supplied calibration file corrects for the response of the microphone capsule and the ear. The miniDSP EARS is the perfect tool for creating EQ filters for the miniDSP HA-DSP headphone amplifier or for any other headphone system with EQ capability.

EARS is available immediately on the minidsp webshop for US$179.

CDSP 8x12

The C-DSP 8x12 is miniDSP’s next-generation processor for high-end mobile/car audio. The powerful 400 MHz SHARC floating-point processor provides pristine high-resolution audio at internal sample rates up to 192 kHz. With a wealth of inputs and outputs in a compact, rugged enclosure, the C-DSP 8x12 is suitable for installations from simple stereo, through surround systems with subwoofer integration, up to advanced multichannel active systems.

The driverless USB interface is used to configure miniDSP’s powerful but easy-to-use audio processing: parametric EQ on all inputs and outputs, compressors and adjustable time delay on all outputs, crossovers up to 48 dB/octave, and an advanced matrix mixer. Four complete processing configurations are stored in flash memory for instant recall with a wired or infrared remote.

Hardware features dedicated to the vehicle environment include an on-board isolated power supply, remote trigger input/output, a wired remote for dash or console mounting, and a microSD card slot for offline configuration and firmware updates.

Available now on miniDSP's webshop @ 499USD, check out the user manual and product datasheet for more details on this exciting new platform!




miniDSP is proud to announce the immediate availability of the DDRC-24, the world’s smallest Dirac Live® processor. Dirac Live®, the world’s premier room correction solution, corrects both the room and the loudspeaker with a unique proprietary mixed-phase algorithm doing both impulse and frequency response correction. This technology is used not only in home stereo systems but also in cinemas, recording studios, and luxury cars. With the release of the miniDSP DDRC-24, it is now available in an unbelievably compact hardware unit.

Powered by a 400 MHz Analog Devices SHARC processor, the miniDSP DDRC-24 accepts a stereo input signal via asynchronous USB Audio, digital optical, or analog. The four analog outputs can be matrixed to the two Dirac Live correction channels in any way. Combined with a full suite of miniDSP’s tried-and-tested DSP functionality (parametric EQ, crossover, biquad programming, delay and gain), the result is an extraordinarily flexible processor for applications ranging from straightforward stereo room correction through to active loudspeakers, subwoofer integration, sub-sat systems, and as a component of active multichannel and home theater systems.
