amirm , your majesty, can I haz phase response graph pleeeease?
amirm , your majesty, can I haz phase response graph pleeeease?
I am not happy with the phase measurements I am getting out of AP software. For some odd reason, its normal phase measurement is only relative to the other channel. I have to use a special sweep mode that generates input to output phase difference but has artifacts of its own. When I get confidence in that, I will post.
????I have much simpler idea, make two tone sound file in Audacity that has two sinewaves, each is -6db and one is 16 KHz and other 4 KHz. Then post picture of original waveform and the Apple adapter output waveform, this is simple, fast, fool proof and very effective way to investigate the phase response.
Correct.
I bought one and one came free with another dongle. They both worked. This is the one I bought: https://smile.amazon.com/gp/product/B07B47V967/ref=oh_aui_search_asin_title?ie=UTF8&psc=1@amirm can you share which specific USB (male)——>USBc (female) adapter you used successfully?
Sure:Its almost perfect, just one thing, make the waveform graph windows same lenght. The first is 700u and second 180u, its hard to see if the windows arent same lenght.
Make them both 700u please.
It does show up as a recording device:just curious, does the Apple USBc device also appear in the RECORDING tab of Windows Sound? In other words, does the combo of the USB-c adapter + Apple USBc headphone device also expose an Input to the host PC? We know that via an iPad this item is also an ADC+MicPre of sorts.
Yes.Is this the AP in loop with itself?
Yes.
The apple USB C dongle is limited to 80mV in android stock but with the correct tinymix commands (root needed), will put out 1 volt. Third party android drivers (Neutron) do not work. My measurements (not done with the same quality gear) also show that this Dac dongle is one of the best available especially at 9 dollars.
What is that that tinymix thing. never heard of it. I didnt meant Neutron, I meant that pro usb player or whatever it is called. Also, why its limited to 80mV? Did Apple put that voltage limiter there on purpose to precent people from using it with Android?
I have used these and the ones that came with one of my dongles: https://smile.amazon.com/gp/product/B07B47V967/ref=oh_aui_search_asin_title?ie=UTF8&psc=1Which USB A to USB C adapter did you use for the test? Just bought the Baseus but it doesn't seem to work with Xiaomi USB C to headphone jack dongle. I am waiting for the Apple dongle to arrive, did you change anything in Windows to make it work?
