16 in 16 out DSP, Arduino

Hi hi

I'm starting a new project with the following specs

1 - 16 analog audio inputs 
2 - 16 analog audio outputs 
4 - Matrix mixing capability 
5 - Uses SigmaStudio 
6 - Minimum sample rate = 96 KHz

Which DSP chip would you recommend?

Is ADAU144x my best/only option?


It seems like I should start with an EVAL board... is there a board with 16 channel input and output?


EVAL-ADAU1142 looks like it has 16ch out,  but only 8ch in... can I add 8 channels easily?

EVAL-ADAU1442 Evaluation Board | Analog Devices 

I ultimately would want to control the chip from a microcontroller. From my what I've seen on the forum, it seems I would flash an initial program via SigmaStudio, have the chip boot in standalone mode, then send i2c commands from the microcontroller. Is this right?

I'm imagining writing the microcontroller program in Arduino. Does an Arduino library exist?

Has anyone used this AIDA library with ADAU144x? GitHub - AidaDSP/AidaDSP: AidaDSP project official repo 

Thanks

  • Hi, maybe not so many people know that exists a version of Aida DSP library for ADAU144x DSPs.
    You can find it here.

    Since I didn't have an Aida DSP board with ADAU144x, a user of the library sent me his custom board on which I had tested the methods. The unstable part at the moment regarding ADAU144x family is the Java tool which I provide for automating the generation of a c header file from Sigma Studio's .xml own generated file. You can find the binary here.

    Help in the debug of the Java tool is always welcomed since it's difficult for a single user to cover all the cases.
