Why am I seeing different output rate conversion ratios for the 4 ASRCs I am using when I have them set to the same source and output rate? In the ASRC tab I see the following output rate conversion ratios after reading all registers:

ASRC0: 3763

ASRC1: EB3

ASRC2: EB3

ASRC3: EB3

I have a USB Streamer connected to ADAU1452 Eval board through serial port#3 (SDATA_IN3). Set ASRC 0-3 to capture input data from channel pairs 40-47 respectively.

My application is working but just curious why one ASRC is converting at a different ratio than the others?

Thanks

Mike,

That is odd, but 3763d = 0xEB3. It's GUI bug mixing hex and decimal display.

Which version of the software are you using? I'll report it to the developers. Thanks for the feedback.
