Superb little DSP'
I've bought this DSP kit initially for fun. However, it was a life saver!
I had programmed it with a dynamics compressor, to be able to get rid of the LOUD action sounds and inaudible dialogues on Netflix (and movies in general). It does the job very well, you don't get a heart attack each time family is watching some movies...
In Sigma Studio there are a lot of interesting algorithms and other applications.

Game changer
Wow!
Bought this DSP board just for fun...and...it's really a game changer for any DIY project!

I'm using it swapping an Audiocontrol 6XS electronic crossover and driving one of my old DIY speakers (SBAcoustic SB17NRX-C35 + ScanSpeak D2010).
Results are astonishing, not only for the price...

It's really like to play a game setting up serious things like:
All levels +
24dB Linkwitz-Riley Filters +
Baffle Step loss compensation (curve choice via potentiometer) +
Notch Filters +
Time Delay...

Sigma Studio works perfectly and is quite intuitive (from my personal point of view).

Well, for this price it's an incredible product giving Hi-Fi sound quality and...unique DIY freedom!

I hope that in future we can buy also an evolution of this concept with more powerful DSP, direct SPDIF input (+output), different DACs, 2x6...etc.

Great purchase, thanks!

Powerful device
You can do a lot of audio processing with this small unit as shown in this video:

To reprogram the 256144-bytes EEPROM: connect the USBi programmer, move the jumper to USBi instead of self-boot and put the jumper on WE (write enable).

After you get "WRITE SUCCESSFUL": disconnect the USBi programmer, move the jumper back to self-boot, remove the WE/WP jumper (write protection) and connect a USB cable or a power source.
