Im in the middle of a small boombox project and i found these dsp modules from Wondom based on the dsp chips form analog devices. Does anyone have any experience with them or know of a cheaper alternative to these dsps?
Looks like an interesting project, especially the daughter board on top of the Sure ADAU1701 board. Any link to the project?
I don't have a thread about the project on here, I did post it on a dutch DIY audio forum though.
The board ontop of the DSP board is a cheap PCM5102 DAC. The Hypex UcD32MP I used needs an input buffer with gain. The PCM5102 DAC had a bit more output gain than the onboard DAC so I cheated by using that and not implementing an input buffer with gain.
I just ordered the dsp board and programmer. I have same intentions as OP, a boombox project. It has TPA3118 amp with 6S li-ion battery, BT-receiver and Dayton Audio ND91-4 in a ~2,5 liter box with two 4" passive radiators.
I have two Sure/Wondom adau1701 boards with their programmer. I'm running SigmaStudio on a mac with Parallels and can load custom programs onto the boards, which I combine for an 8 channel setup by splitting the analog inputs. I'm wondering if the Sure "ICP3" programming board can also program ADAU1452 boards not from Sure.
Here's a link to another thread about the Sure DSP:
New? Sure Electronics ADAU1701 Module
FlaminBeatz, cheers for the heads up on the PCM1502, just ordered six of them to set up a couple of dsp boards using the PCM1502 as differential outs, assuming I can parallel the i2s lines.

If one want to use the wondom ICP3 wireless over wifi from the computer i can share a solution i tried today.
by using this firmware Hardware | VirtualHere on a GL-MT300N-V2 / Mango - GL.iNet i made a wireless usb port that works with Sigma Studio.
I have made a proof of concept test plugging in and out the programer a couple times and uploaded a design to the eeprom. Seems stable.
The cute little router have about the same footprint as the wondom boards to, so a compact battery powered solution can be made if one want to sit in the comfort of the sofa and update the Adau1701 boards.
