Developers at Auverdion based in Verden, Germany have created the new open source DSP offering users eight inputs and eight outputs with USB Audio Class 2 and wireless control via Wifi and Bluetooth. The aptly named freeDSP-aurora DSP has this week been launched via Kickstarter.
The new hardware supports macOS, Linux or Windows 10 operating systems and a XMOS XE216-512-TQ128 MCU is used to expose an USB Audio Class 2 compliant interface. The ESP32 MCU controls the operation of the DSP and support for both WiFi and Bluetooth connectivity can support peripherals such as a rotary encoder, display, temperature sensor, PWM controlled fan and IR sensor.
“The freeDSP-aurora is a cost-effective real-time audio signal processing solution for audio enthusiasts, researchers, and the do-it-yourself community. It is a bare circuit board that can be incorporated into your own projects. It comes with no housing. Easy assembling and simple programmability are the main focus. It is based on Analog Devices’ ADAU1452 DSP chip.”
Pledges are available from €195 and will start shipping out to backers during May 2019. The FreeDSP-aurora offers a wide range of DSP processing options and interface controls with easy programmability. It can be used in various audio applications for example .
– Room compensation / system equalisation
– Digital crossovers in active loudspeaker concepts
– Multiband dynamics processing
– Delay compensation / phase shift
– Bass enhancement
– Subwoofer integration
– Stereo image widening
