Wow awesome. I found SmartRF04EB on ebay. I did my mouser cart and found suitable components. All i need now is geber files from altium projet in post #24. Can someone knowing how to extract well gerbers can share them ? I'd like to send order to jlcpcb. I know, easy way would be to directly buy dayton's dsp-lf, but it's way less fun
.Thanks,
Damien
I don't know, please ask Artyom app developer about it.
2in/out will not be developed, the same as "slow start" and other minor and easy solvable tings. We have to keep the same HW for our customer's compatibility.
With the same hardware, would it be imaginable to implement/get a firware version with superbass block (upper harmonic to fake low frequency) maybe in place of the sub harmonic synth ?

Guys, I don't know how to explain to you better than I did.. If we'll change anything, what will do our customers like Earthquake which sold/produced about 10K subwoofers with iWoofer, or Dayton DSP?? Can you imagine if I go to make trouble for them because of you want to try suprerbass instead of SHS?
I suppose new firmware are loaded via app via blutooth to dsp.
You already have 2 version of the app.
It would be third version, more hifi/live/musician oriented with superbass (sub synth is more a effect for home cinema). I'm pretty sure there should be enough idea for a third version, 5-10 € each of course. And it should open iwoofer plateforme to product maker that seach to do as the soundblock 2 that uses this kind of effect.
Ok i'm joking/dreaming a bit, it's yet enough awesome to have this project and all details presented here. If you've finished with this project, I understand. Working on this with Dayton and Earthquake (and i've found others on the web ) surely make thing now less flexible.
Thanks a lot for sharing to diyaudio community !

iWoofer was designed as a cost-effective DSP with room corrector for subwoofers. "Superbass" is the feature intended for small speakers like tiny battery-powered Bluetooth speakers. Such speakers usually play from 100-200Hz i.e. entire iWoofer's weapons are 100.00% useless there. Hence, iWoofer needs "Superbass" the same as subwoofer may need FM radio, or a pencil sharpener function.
Few dB at lower corner cost a lot power/size/driver due to needed xmax to move air or box volume needed to increase efficiency. So psychoacoustic effect is welcome from 25 to 45 Hz where we usually have hard time choosing box/amp compromise. So generated 50 to 90 Hz h2 harmonics is here really welcome, and still in a bandpass that doesn't have issues with localisationand that can be output by a sub. It's classical as missing fondamental in 5 bass string played on high power cab that can't reproduct the 35hz of the low B but count on harmonics recognition. Of course it can be uses with small cheap system too in higher bandwith but that is not my point. Still, thank for taking time to answer.
Can you provide the contact information of Artyom developers? Thanks

Delayed start, I used a relay + delay circuit to achieve, there is no power-on shock under any circumstances.
2In 2OUT, I made two iwoofer implementations on a PCB.
At the same time, I found that the output of ADAU1761 is balanced, so we use balanced amplifier circuit and XLR interface.
Maybe you are already working on a solution for this...I just haven't seen it yet. For android devices, could you program iwoofer to use something like a Dayton Audio iMM-6?
Iit looks like a great app and I'm very interested in the room correction feature, but I don't have (nor am I interested in buying) an i-device.
Thanks!

Use This one. Purchase of goods presented a software tool, can convert the REW result to IWF preset file

Hi all,
I tried to make iwoofer using 4.02v pcb
what would be the problem.
i used a 2.7nH for L3 instead of 3nH. all other components are same as schematic.
Any help would be great !!
Thanks..

i was able to program the CC2540 using CCdebugger and Tiflash programmer and the firmware file from HW_package. but after that nothing happens. I cant see any bluetooth device on my mobile. led just blinks on poweron and then nothing.
what would be the problem.
