Maximum sampling on USB audio class 1.0

[Stabilo]

Hello,

Is it possible to use USB full speed (12 Mbit/s) combined with audio class 1.0 to transfer 16bit audio data sampled at 384ksps ?

According to my calculation, I need to transfer 768 bytes/ms over USB:

384000 * 16 = 6144000 bits/s

= 6144 bits/ms

= 768 bytes/ms

So in theory, it fits in the 1024 bytes/ms restriction of the USB full speed.

But the usb audio class 1.0 stands that the maximum sample rate is 78 kHz...

Is it possible to achieve transferring 16bits data at 384ksps ?

Thanks

Yes one channel mono as you see or stereo on 192k max but ...

But ? 🙂

Is it tricky to implement ?

But for example drivers in PC dont support this on UAC1

Thank you for the information !
