Sure, I use a hifiberry beocreate DSP board (just because I had it lying around) which has an analog devices ADAU1451 DSP and decent power supplies onboard.
I connect the Cosmos with I2S to the DSP board (I abuse the RPI pins for this)
The DSP can have the Cosmos as clock master or can use...
Awesome piece of software, thanks!
A great addition would of course be an ability to make a level vs imd measurement like Amir does in his reviews (something REW sadly cant do )
that would be very nice to have! I use my cosmos adc connected to a adau1452 dsp board and than connected over spdif to my rme soundcard, I would do the same with cosmoc dac.
( your electronics are awesome, but rme's drivers are just without any doubt the best out there, and have been since the...
most pro microphones have sensitivity in the range 3-50mV/pa
so that means 94dBSPL gives 3-50mV rms output
the quitest mics ( ie akg c414 https://www.akg.com/Microphones/Condenser Microphones/C414+XLII.html ) have a single range of ca. 6dBSPL to ca. 140dBSPL so 134dB dyn range.
at a sensitivity...
that is great news!
I assume the adc will be clock master in that situation?
And will it be nessecary to cut traces/ modify traces on the pcb for this use, or can it be used in parallel with the usb output?
Much thanks for all your efforts, you are really doing something special!
Hmm, interesting..
We could also try spherical cap extrapolation from the aktools to extrapolate the measured points to the exact needed grids maybe?
I am working on a script with databases from berlin and aachen in which we can place a genelec 8020 or QSCK8 that was measured as sofa dataset...
Yes I am (we are) aware, but I want to have the flexibillty of a cylindrical grid; this allows you to make a much easier array with the possibillity of measuring large cabs (I want to be able to measure cabinets of 1.2x1.2x1.2m. See post 296
source separation with offset destection working pretty well:
Cardioid with 2 disturbing sources outside measurment cylinder: max 0.5dB deviation @ 250 Hz with 9th order
Next step I will use aktools room to simulate a " real" reflective small room around the setup
biggest challenge now is...
I think that beamforming might not be the best option for acoustic center finding in this case, because we know what the input stimulis and min/max time of flight is.
I think that the multilaterarion option I am testing with is promising, I only need to get unwrapped phase for the frequencies of...
