Aida DSP is an audio shield for Arduino

• Compact design size (Arduino shield form factor)
• Low noise design for audio applications
• 2 mono inputs 4 mono outputs
• 24 bits, 48/96/192kHz
• Dedicated crimpable connectors to host encoder, buttons and pots
• Expansion connector with available signals from DSP
• Available open source examples for Arduino boards
• Available open source low level libraries for Arduino Uno/Mega/Due/Zero

DSP firmware is developed in Sigma Studio, a intuitive graphical design tool. From Sigma Studio you can generate an .xml file which contains DSP firmware and then with our Java tool you can generate a C header file to be used in the Arduino IDE.

Now you're ready to code a sketch that communicates with the DSP in real time to control its algorithm using Aida DSP official Arduino API library.

Basically you can manage your UI (user interface: buttons, faders, etc.) with Arduino and then let the DSP do the whole hard work of processing audio with superb quality. For example you can use the DSP to generate a sine tone and change its frequency and amplitude with a pot wired to Arduino's analog input. Check out our examples on Github!
